Description of Embodiments [00121 Hereinaftel; a plurality of ernbodi~~~eonft st he present disclosure will be described with reference to the appended drawings. The description \vill proceed in 10 the following order. 4-1. First embodiment> 4-2. Modified exatnple of first embodiment> Q. Second embodiment> <3. Third embodiment> 15 <4. Content common to embodiments> <5. Application examples> <6. Modified examples> Embodiments which will be described below are exemplary examples of the present disclosure, and the content of the present disclosure is not limited to the 20 following embodiments. [0013] First of all, at1 exatnple of a configuration of an electronic device according 25 to the first embodiment will be described. For example, the electronic device is a device that deals with a power generation state as sensing inforniation. For example, an electronic device according to the e~ilbodi~lleinst a snlall device that can be worn on at1 organism such as a person or an animal. Of course, an electronic device according to the enlbodiment tilay be a stationary device or one installed in 30 various kinds of devices. [00 141 FIG. 1 illustrates an cxa~nplco f a schematic configuration of tile electronic device according to the first embodiment. An electronic device 1 includes, for example, one or more of modules. As illustrated in FIG. 1, the electronic device 1 includes, for example, four modules (a inodule 10a, a tnodule 2023, a module 30a, and 5 a module 40a). The modules include at least a power generating unit that generates electric power according to a surroundi~ig environment, a state transition unit that causes a state to transition according to the electric power supplied fiom the power generating unit, and an output unit that ou~tputsp redetermined information according to the transition of the state of the state transition unit. 10 [0015] The power generating unit generates electric power based on energy existing in a su~~ouuidinegn virot~ment. The power generating unit, for example, generates electric power based on vibrations or motion of the user of the electronic device. For example, an electrostatic type, an electromagnetic type, an inverse 16 tnagnetostrictive type, or a piezoelectric type may be used as a power generation method, and there is no preference for a power generation method. The power generating unit may generate electric power based on light (for example, an indoor electric bulb or sunlight. The power generating unit may be a thermoelectric conversion element (for example, an element that generates electric power using a 20 Seebeck effect or a Tllomson effect, a thernloelectric power generation element, or an element that performs thernnornagnetic power generation) that generates electric power using a temperature difference. The power generating unit may be an enzyme battery cell (also referred to as a "bio-battery cell") that generates electric power using sugar. The power generating unit may generate electric power using 26 capacity coupling or electron~agnetic coupling by any one or a combination of inductance, capacitance, and reactauce (LCR) components, a capacitor, an antenna, a rectenna, and the like, for example, using a radio wave. The power generating unit may perform near electrotnagnetic field power generation, that is, may generate electric power based on energy obtained by getting the electronic device close to a 30 predetermined device. A known schc~nesu ch as a magnetic field resonauce scheme, an electrolnagnetic induction schcmc, electrolytic coupling, or an electric field resonance scheme may be applied as a near electric filed power generation sche~ne. In addition to the exenlplified clcnlents, any other known power generation elenlent nlay be applied as the power generating unit. [0016] 5 The modules of the electronic device 1 nnay include one or more power storage elements. The power storage element is used, for example, according to the purpose of storing the electric power generated by the power generating unit. As the power storage element, in addition to various kinds of secondary battery cells such as a lithium-ion secondary battery cell, an electric double layer capacitol; a 10 lithium-ion capacitor, a polyacene-based organic semiconductor (a polyacenic semiconductor (PAS)) capacitol; a Nanogate capacitor ("Nanogate" is a registered trademark of Nanogate Aktiengesellschaft), a ceramic capacitor, a film capacitor, an alun~inu~enle ctrolytic capacitor, a tantalum capacitor, or the like may be used. A combi~lationo f po\ver storage elements may be used according to the purpose. 15 [0017] The state transition unit causes its state to transition according to the electric power supplied from the power generating unit. The electric power supplied from the power generating unit may be supplied to the state transition unit directly or through the power storage element. The electric power generated by the power 20 generating unit may be appropriately increased or decreased and then supplied to the state transition unit. [0018] The state transition unit is configured with, for example, an integrated circuit (IC) including one or more elements. Examples of the state transition unit 25 include a switching element such as a transistor, a diode, a reset IC, a regulator IC, a logic IC, and various kinds of ope~.ation circuits. A circuit configuration in an IC may be appropriately changed as long as the function of the state transition unit call be imnplemented. In the following description, a reset IC is assumed to be used as the state trausition unit. 30 [0019] For example, the state transition unit transitions between twvo states of ON and OFF according to the electric power supplied fion~th e power generating unit. For example, the state transition 1111it tra~lsitio~flrso nn an OFF statc to an ON state when tllc powcr generation atnoutnt output fro~om the power generating unit is a predetermined a~nlount or tnore. For exannple, the power generatio11 amount is 6 specified by any one of a voltage, an electric current, electric power and electric energy or a combination thereof. Further, \vhen the electric powver of the power generating unit is supplied to the state transition unit through the power storage element, the state transition unit tra~lsitio~nfrso m the OFF state to the ON state when the power generation amount charged in the power storage element is the 10 predetermined amount or inore. [0020] The state transition unit may transition atnorlg three or more states: The state transition unit preferably stores a state after transition by holding the state, but the state tra~nsitio~unl it may neither hold nor store the state due to a reset or the like. 15 [0021] The output unit outputs the predetermined information depending on the state the state transition unit transitions to. For exanlple, the output unit includes a comnlunication ~lnodule and an antenna for perfornling comn~mnication with an external device different fionn the electrot~icd evice 1, and perforr~lsc onu~lunication 20 based on a predetermined comtnunication standard to output the predeternlined information to the external device. The state transition unit and the communication module may be connected to a control unit, and the co~mn~ut~icatimonod ule may operate according to control by the control unit. The comtnunication module may be configured to include the control unit. 25 [0022] The comnn~unication performed by the communication module may be wireless or wired colllmunication. The wireless com~~~~nicatmioayn be communication using an electromagnetic wave (including infrared rays) or conl~lnunicatio~uls ing an electric field. As a specific scl~enle,a co~~~m~u~nication 30 using a band of several ln~~adredosf megahertz (MI-Iz) to several gigahertz (GHz) such as "Wi-Fi (a registered trademark)," "Zigbee (a registered trademark)," "Bluetooth (a registered trademark),'' "Bluetooth low energy," "ANT (a registered trademark)," "ANT+ (a registered tradenlark)," or "Enocean (a registered trademark)" may be used. Near field co~lnnunication( NFC) may bc used. [0023] 5 For exanlple, when the state transition unit transitions to the ON state, the output unit operates, and connnunication is perfomled. The predetermined infor~nationo utput by the output unit is, for example, an identifier (ID) allocated to each module. 111 addition to the identifier, the predeternlined information may be information of one bit (0 or 1 as a logical meaning) corresponding to the state of the 10 state transition unit. For example, when tlie modules include different power generating units, the allocation of the identifier to each nlodule has an equivalent meaning to the allocation of an identifier to each power generating unit. [0024] The identifier allocated to the module may be an identifier that is allocated 15 in advance or may be an identifier that is allocated each time. For example, \vhen the electronic device 1 establishes a connllunication connection with another device, the identifier may be allocated to each module so that the allocated identifier is used. [0025] In this example, the communication modules of tlie respective niodules are 20 configured to perform con~munication independently. Thus, it is unnecessary to control, for example, a timing at which each comniunication module performs cotnn~unication. [0026] 5 FIG. 3 illustrates an cxat~lpleo f a system using the electronic device. As described above, tlie electronic device 1 perfornls conl~llunicationx vitlith an external device using the con~munication nodules of the respective modules. An external device is, for example, a database device DBI, a database device DB2, or a personal computer PC connected to the electronic device 1 via a network NT. The external 10 device may be a device used in a company or a device used by an individual. The external device may be a device connected to the electronic device 1 via a cable. [0045] The electronic device 1 [nay perform comnlunication with the external device via a relay device. A smartphone SH that is owned by the user and located 15 at a relatively close position to th~electronicd evice may be used as the relay device. The relay device may be a tablet comptiter or a laptop personal computer in addition to a smartphone or may be one electronic device I when there is a plurality of electronic devices 1. The relay device is also the external device. A specific example (an applicatiotl example) of the system using the electronic device ~villb e 20 described later. [0046] An example of tlie flow of a process of the modules in the electronic device I will be described with reference to a flowchart of FIG. 4. The followi~ig 25 description will proceed with an example of the flow of a process of the module 1Oa. The flows of processes of the other modules are substantially the same as that of the module 10a, but there nlay be a difference according to the co~lfiguratioo~f ~t he module. For example, the processes of the respective ~llodulesa re independently performed. 30 [0047] In step STlO, the po\t7er generating unit 100 (it1 this example, the solar power generating unit 11) geuerates electric power. For esa~uplc, when the user \\caring the electronic device 1 goes outside under fine \\leather, the power generating unit 100 is irradiated wit11 sunlight, and thus the power generating unit 100 generates electric power. Of course, when the outdoor weather is rainy or 5 cloudy, the power generating unit 100 does not generate electric power or generates slight electric powel: Then, the process proceeds to step ST1 1. [0048] In step ST11, the electric power generated by the power generating unit 100 is supplied to the capacitor 105 serving as one of the power storage ele~nentsth rough 10 the regulator IC 101 or the like. Then, the capacitor 105 is charged, and the voltage of the capacitor 105 is increased. Then, the process proceeds to step ST12. [0049] In step ST12, it is determined whether the voltage of the capacitor 105 is the reference voltage or higher. When the voltage of the capacitor 105 is smaller than 15 the reference voltage, the process returns to step ST12. When the voltage of the capacitor 105 is the reference voltage or highel; the process proceeds to step ST13. [0050] In step ST13, as the voltage of the capacitor 105 becomes the reference voltage or higher, the reset IC 106 transitions from the OFF state to the ON state. 20 Further, as the voltage of the capacitor 105 becomes the refereuce voltage or higher, the state of the reset IC 106 transitions, and the determillation process of step ST12 is not performed by a certain functional block. As the reset IC 106 transitions to the ON state, the output voltage of the capacitor 105 is supplied to the MPU 107. Then, the process proceeds to step ST14. 25 [0051] In step ST14, the MPU 107 operates using the electric power supplied from the capacitor 105 as a po\lrer source. For esatnple, the MPU 107 reads a program stored in the ROM lO8a, and performs a process according to a code described in the program. Then, the process proceeds to step ST15. 30 [0052] In step ST15, the MPU 107 supplies the electric power to the co~~m~unicatmioond ule 109 and controls the co~ml~unicatiomno dule 109. In other words, the MPU 107 instructs the conun~~nicationtn odule 109 to start coi~ununicationa nd to transmit, for example, the identifier of the module 10a to an external device. Then, the process proceeds to step ST.16. 5 [0053] In step ST16, the com~nnnication niodule 109 perforlns co~ntuunication according to the control by the MPU 107. The cotnmunication module 109 transmits, for example, the identifier allocated to the module 10a to the external device according to a predetermined communication scheme. The external device 10 that has received the identifier of the module 10a can recognize that, for example, the solar power generating unit 11 including the modale 10a has generated an energy amount for operating all or a part of the system. [0054] Although not illustrated, as the MPU 107 operates, the voltage of the 15 capacitor 105 is decreased, and thus the reset IC 106 transitions from the ON state to the OFF state. As the power supply to the MPU 107 is interrupted, the operations of the MPU 107 and the communication module 109 are suspended. For example, when the power generation of the solar power generating unit 11 is continued, the above process is repeated. 20 [0055] The above process is performed as the power generating unit generates a predetermined amount or more of electric power. In other words, for example, when a minimum electric power for operating the MPU and the communication module is generated or charged, syste~n (module)-specific information may be 25 generated and output. The user of the electronic device need not perform a special operation. In the electronic device, the power generation state of the power generating unit is used as sensing information. In other words, the power generating unit fi~nctionsa s a sensor and a power source. Thus, it is unnecessary to install a unique configuration (for example, a sensor such as an acceleration sensor, a 30 gyro sensol; a temperature sensol; or a geo~nagnetics ensor) for obtaining the sensing infor~nation. [0056] Since the sensor aid an AD converting unit for processing the sensing itiforniation need not be installed, it is unnecessary to nlount a large battery cell for supplying electric powel; and thus the size of the electronic device can be reduced. 5 Since the size of tlie electronic device can be reduced, for example, tlie user does not feel discomfort even when the user wwrears the electrotiic device. Further, since the size of the electronic device can be reduced, the electronic device can be easily incorporated into another device. In the electronic device according to the embodiment, it is possible to prevent its operatioti from being suspended by a dead 10 battery that may occur in small electronic devices. [0057] 4-2.M odified example of first embodiment> The process of the electronic device 1 according to the first embodinlent can be modified, for example, as illustrated in a flowchart of FIG. 5. The followitlg 15 description will proceed with different points from the above pr&cess. [OOSS] Tlie process of step ST10 to step ST13 has been described above and thus will be described briefly. As the voltage equal to or higher than the reference voltage is charged in the capacitor 105, the reset IC 106 transitions from the OFF 20 state to the ON state. Then, the process proceeds from step ST13 to step ST20. [0059] As the reset IC 106 transitions to the ON state, the MPU 107 starts its operation. Tlie MPU 107 stores information indicating that the reset IC 106 has transitioned to the ON state in tlie RAM 108b. The MPU 107 stores, for example, 25 the identifier of the module lOa in the RAM 108b. Then, the MPU 107 reads the identifier of the module 1Oa stored it1 the RAM 108b, and instructs the coniniunication module 109 to transmit the identifier to an external device. The process of step ST15 and step ST16 has been described already, atid thus a duplicate description thereof will be omitted. 30 [0060] Further, infortnation different frotii the identifier of the nlodule 10a may be stored in the storage unit 108. For exatnple, a counter majr be installed in the storage unit 108, and tlie nurnber of transitions of tlie reset IC 106 fiotn the OFF state to the ON state may be stored. Then, the t~utiibero f transitions of the tiiodnle 10a to the ON state may be transmitted to the external device together with the identifier of 5 the module 10a. [0061] Further, when the MPU 107 stores the identifier of the module 10a or the like in the RAM 108b, process of step ST22, step ST23, and step ST24 in a flowchart of FIG. 6 majr be performed. 10 [0062] In step ST22, tlie MPU 107 determines whether there is a storage capacity of tlie RAM 108b when a recording process is performed. When there is a storage capacity of the RAM 108b in step ST22, the process proceeds to step ST23. In step ST23, the MPU 107 perforn~sth e recording process on the RAM 108b. When there 15 is not a storage capacity of the RAM 108b in step ST22, the process proceeds to step ST24. [0063] In step ST24, since there is no storage capacity of the RAM 108b, the recording process is perfonned on an external memory. As will be described later 20 in detail, an extension module having various functions may be added to the electronic device. When the extension module has a storage function, the identifier of the tnodule 10a or the like may be stored in the extension module. The MPU 107 may determine whether the extension niodule has the storage function and perfor111 the recording process on the extension niodule when the extension module has the 25 storage function. Further, when there is no storage capacity of the RAM 108b, an overwriting process map be performed. [0064] <2. Second embodiment> Next, a second e~nboditnent will be described. In the description of the 30 second enibodiment, a duplicate description of the same conlponents as in the first enlbodin~entw ill appropriately be omitted. An electronic device according to tlie second embodiment may be configured to output time information indicating a time at which the state of the state transition unit transitions. [0065] 5 The electronic device according to the second embodinlent (referred to approl~riately as an "electronic device 2") includes one or more of modules, similarly to the electronic device 1 according to the first embodiment, The electronic device 2 includes, for example, a module lob, a module 20b, a module 30b, and a module 40b. Each of the n~odules includes, for example, a power generating unit, a power 10 storage clen~enta, state transition unit, and a com~nunicationm odule. [0066] An example of a specific configuration of the module .in the electronic device 2 will be described in connection with an example of the module lob. For example, configurations of the other modules in the electronic device 2 arc the same 15 as the configuration of the n~odule lob, but there may be a difference in a configuration between the modules. [0067] FIG. 7 illustrates an example of a specific configuration of the module lob. Similarly to the module 10a in the electronic device 1, the module lob has a 20 configuration including, for example, a power generating unit 100, a regulator IC 101, a charger 102, a secondary battery cell 103, a capacitor 104, a capacitor 105, a reset 1C 106, an MPU 107, a storage unit 108, and a comniunication tnodde 109. The storage unit 108 has a configuration including, for example, a ROM 108a and a RAM 1OSb. 25 [0068] The module IOb includes a real time clock (RTC) 150. The RTC 150 is connected to the MPU 107, and supplies time infonnation to the MPU 107. For example, a year, a month, and a date may be appropriately set to the time information. Tllc MPU 107 may be configured to include the RTC therein. 30 [0069] Although not illustrated, a power source device for driving the RTC 150 is installed in the electronic device 2. For exalnplc, a secondary battery cell such as a lithium-ion battery cell or a primary battery cell may be used as the power source device. Since power consumption of tlie RTC 150 is small, a coin type small battery cell may be used. The electric power charged in the secondary battery cell 5 103 may be suppliedto the RTC 150. As the reset IC 106 transitions from the OFF state to the ON state, the MPU 107 supplies the time information supplied frollltlie RTC 150 to the connnutiication nodule 109 together with the identifier of the module lob. The cotinnunication tnodule 109 outputs tlie identifier of the module lob and the time information to an external device through comnlunication. 10 [0070] An example of the flow of a process of the modules in the electronic device 2 will be described with reference to a flowchart of FIG. 8. Tlie following description will proceed with an example of the flow of a process of the module lob. 15 The flows of processes of the other modules are substantially the same as that of the module lob, but there may be a difference according to the configuratiott of the module. For example, the processes of the respective modules are independently performed. [0071] 20 In step ST30, the power generating unit 100 (in this example, the solar power generating unit 11) generates electric power. For example, when the user wvearing the electronic device 2 goes outside under fine weather, the power generating unit 100 is irradiated with sunlight, and thus the power generating unit 100 generates electric power. Of course, when the outdoor weather is rainy or 25 cloudy, the power generating unit 100 does not generate electric power or generates slight electric power. Then, the process proceeds to step ST3 1. [0072] In step ST3 1, the electric power generated by the power generating unit 100 is supplied to tlie capacitor 105 serving as one of the power storage eletnents throng11 30 the regulator IC 101 or the like. Then, tlie capacitor 105 is charged, and the voltage of the capacitor 105 is increased. Tllen, the process proceeds to step ST32. [00731 In step ST32, it is determined wvhether the voltage of the capacitor 105 is the reference voltage or higher. When the voltage of the capacitor 105 is srnaller than the reference voltage, the process returns to step ST32. When the voltage of the 5 capacitor 105 is the reference voltage or higher, the process proceeds to step ST33. [0074] In step ST33, as the voltage of the capacitor 105 becornes the reference voltage or highel; the reset IC 106 transitions from the OFF state to the ON state. Furtheel; as the voltage of the capacitor 105 becomes the reference voltage or higher, 10 the state of the reset IC 106 transitions, and the deternlination process of step ST32 is not perfo~med by a certain functional block. As the reset IC 106 transitions to the ON state, the output voltage of the capacitor 105 is supplied to the MPU 107. Then, the process proceeds to step ST34. [0075] 15 In step ST34, the AlIPU 107 operates using the electric power supplied from the capacitor 105 as a power source. The MPU 107, for example, reads a program stored in the ROM 108a, and performs a process according to a code described in the program. Then, the process proceeds to step ST35. [0076] 20 In step ST35, the MPU 107 supplies the electric power to the co~nmunication module 109 and controls the conmlunication module 109. The MPU 107 supplies, for examnple, the identifier of the module lob stored in the ROM 108a and the time information supplied from the RTC 150 to the comrnunicatio~l module 109, and gives an instruction to output the infor~nation. Then, the process 25 proceeds to step ST36. [0077] In step ST36, the con~munication module 109 performs co~mnunication according to the control by the MPU 107. The communication module 109 transmits the identifier allocated to the module lob and the time infor~nationto the 30 external device according to a predetermined co~n~nunicatioscnh eme. For example, the external device cau recognize the power generation of the solar power generating unit I I arranged in the nlodule 10b and a power generation timing of the solar power generating unit 11. Furtheel; when the external device receives the identifier of the nodule 10b and the time infor~nationa gain, the external device can recognize time intervals at which the state transition unit transitions to the ON state, that is, power 6 generation intervals of the solar power generating unit 11 without using the titne information at an external device side or without generating the time infonnation. [0078] The MPU 107 may store the time infortnation indicating a time at which the reset IC 106 transitioned to the ON state in the RAM 108b. Tlms, for exanlple, 10 even when communication is performed in a state in which infortnation is accutnulated instead of performing con~tnunicatione ach time, a notification of the time information related to the state transition can be given to the external device side. [0079] 15 Although nit illustrated, as the MPU 107 operates, the voltage of the capacitor 105 is decreased, and thus the reset IC 106 transitions from the ON state to the OFF state. As the power supply to the MPU 107 is interrupted, the operations of the MPU 107 and the comnunication module 109 are suspended. For example, when the power generation of the solar power generating unit 11 is continued, the 20 above process is repeated. [0080] <3. Third embodinlent> Next, a third embodiment will be described. Itt the descriptio~lo f the third embodiment, a duplicate description of the same cotnponents as in the first 25 etnbodiment will appropriately be omitted. [OOX 11 The electronic device according to the third emboditnetlt (referred to appropriately as an "electronic device 3") includes one or more of n~oduless, imilarly 30 to the electrotlic device 1 according to the first embodiment. The electronic device 3 includes, for example, a inodule IOc, a nlodule 20c, a mnodule 30c, and a module 40c. Each of the modules includes, for exanxple, a poxves generating unit, a power storage element, a state transition unit, and a cornm~~nicatiomno dule. [0082] An example of a specific configuration of the module in the electronic 5 device 3 will be described in connection with an example of the module 10c. For example, configurations of the other n~odulesi n the electronic device 3 are the same as the configuration of the module 10c, but there may be a difference in a configuration between the modules. [0083] 10 FIG. 9 illustrates an example of a specific configuration of the lilodule 1Oc. Similarly to the module 10a in the electronic device 1, the module 10c has a co~lfigurationin cluding, for example, a power generating unit 100, a regulator IC 101, a charger 102, a seconda~yb attery cell 103, a capacitor 104, a capacitor 105, a reset IC 106, an MPU 107, a storage unit 108, and a commonication module 109. The 15 storage unit 108 has a configuration including, for example, a ROM 108a and a RAM 108b. [0084] The nlodule 10c further includes a clock generating unit 160. The clock generating unit 160 generates a clock, for example, with a predetermined cycle. 20 When the clock generated by the clock generating unit 160 becomes a predetermined set value, the clock generating unit 160 performs control such that the output voltage of the capacitor 105 is supplied to the reset IC 106. For example, a switch is installed between the capacitor 105 and the reset IC 106, and when the clock becomes the predetermined set value, the clock generating unit 160 svlitches the 25 switch fiom the OFF state to the ON state. The clock generating unit may be installed in a device different fiotn the electronic device 3, and control may be perfolmed by the clock generating unit outside the electronic device 3. [0085] The electric power is supplied fiom the capacitor 105 to the clock 30 generating unit 160. The clock genesating unit 160 operates using the electric power supplied fiom the capacitor 105. A power source device for operating the clock generating unit 160 may be installed. For example, a secondary battery cell such as a lithium-ion battery cell or a primary battery cell may be used as the power source device. Since the power consuniption of the clock generating unit 160 is small, a coin type small battery cell may be used. The electric power charged in the 5 secondary battery cell 103 may be supplied to the clock generating unit 160. [0086] An example of the flow of a process of the niodules in the electronic device 3 will be described with reference to a flolvchart of FIG. 10. The following 10 description will proceed with an example of the flow of a process of the module 1Oc. The flows of processes of the other modules are substantially the same as that of the module 10c, but there may be a difference according to the configuration of the module. For example, the processes of the respective nodules are independently perfornied. 15 [0087] In step ST40, the power generating unit 100 (in this example, the solar power generating unit 11) generates electric pourer. For example, when the user wearir~g the electronic device 3 goes outside under fine weather, the power generating unit 100 is irradiated with sunlight, and thus the power generating unit 20 100 generates electric power. Of course, when tlie outdoor weather is rainy or cloudy, the power generating unit 100 does not generate electric power or generates slight electric power. Then, the process proceeds to step ST41. [OOSS] hl step ST41, the electric power generated by the power generating unit 100 25 is supplied to the capacitor 105 serving as one of the power storage elements through the regulator IC 101 or the like. Then, the capacitor 105 is charged, and the voltage of the capacitor 105 is increased. Then, the process proceeds to step ST42. [0089] In step ST42, the electric power of the capacitor 105 is supplied to the clock 30 generating nnit 160. Tlle clock generating unit 160 operates using the supplied electric power. Then, the process proceeds to step ST43. [0090] In step ST43, the clock generating unit 160 determines whether the clock generated by the clock generating unit 160 has become a set value. When the clock has not beconle the set value, the process returns to step ST43. When the clock has 5 become the set value, the clock generating unit 160 performs control such that the voltage of the capacitor 105 is supplied to the reset IC 106. Then, the process proceeds to step ST44. [0091] In step ST44, it is determined whether the voltage of the capacitor 105 is the 10 reference voltage or higher. When the voltage of the capacitor 105 is neither the reference voltage nor higher, the process returns to step ST43. Then, it is determined again whether the clock generated by the clock generating unit 160 becomes the set value. When the voltage of the capacitor 105 is the reference voltage or higher, the process proceeds to step ST46. - 15 [0092] In step ST46, the MPU 107 operates using the electric power supplied from the capacitor 105 as a power source. The MPU 107 supplies the electric power to the co~nmunicationm odule 109, and controls the cotntnunication module 109. The MPU 107 supplies, for example, the identifier of the module lob stored in the ROM 20 108a to the communication module 109 and gives an instruction to output the infornlation. Then, the process proceeds to step ST47. [0093] In step ST47, the co~nmunication nodule 109 performs comilunication according to the control by the MPU 107. The cotnmunication module 109 25 transmits the identifier allocated to the nodule 10h to an external device according to a predetermined connnnnication scheme. [0094] Sinlilarly to the modified example of tlie first embodiment, the h4PU 107 may perform the recording process on the RAM 108b. Sinlilarly to the second 30 embodiment, the time infornlation indicating a time at wlvhich the reset IC 106 transitioned to the ON state may be output fro111 the RAM 108b to the external device. [0095] Although not illustratcd, as the MPU 107 operates, the voltage of the capacitor 105 is dccreased, and thus the reset IC 106 transitions fron~th e ON state to the OFF state. As the power supply to the MPU 107 is interrupted, the operations 5 of the MPU 107 and the comn~unication n~odule 109 are suspended. For example, when the power generation of the solar power generating unit 11 is co~itinued, the above process is repeated. [0096] <4. Content common to embodiments> 10 The configuration and operation of the electro~~idce vice of the present disclosure have been described using the electronic device 1, the electronic device 2, and the electronic device 3 as examples. Next, content that can be applied to the electronic devices in common will be described using the electronic device 1 as an example. 15 [0097] Since the electronic device 1 can be reduced in size, the electronic device 1 can be incorporated into another device or at1 accessory as an accessory, easily worn on an organism such as a person, an anitnal, or aa outdoor tree, and ca~ried. Examnples of the accessory include a bracelet, a pendant, a ring, an easring, a hair 20 band, and armot The electronic device 1 may be attached to glasses, a hat, shoes, a bag, or the like usually used by the user. Of course, the electronic device 1 is not limited to one that is worn on an organism and carried. The electronic device 1 map be placed on a desk or nlay be placed on a thing (for example, a vehicle) other than an organism. 25 [0098] FIG. 11 illustrates an example of a housing in which the module (for example, the module 10a) in the electronic device 1 is accommodated. A housing 201 has, for example, a cross section of an elliptical shape. The size of the housing 201 can be appropriately set. As an exan~plet,h e size of the housi~~2g01 is set to a 30 size of about a fingertip. Tile housing 201 is n~adeo f a light transmissi\re member such as glass or plastic so that the power generating unit accotnn~odated in the housing 201 is irradiated with sunlight or indoor light, [0099] FIG. 12 an example of a simplified internal configuration of the housing 201. The respective conlponents of the module 1Oa are accommodated in the housing 201. 5 For exatllple, a substrate 210 is accommodated in the housing 201, and the respective components of tlie module 10a are mounted on either or both of the surfaces of the substrate 210. The periphery of the module 10a may be molded by resin or the like. For example, the solar power generating nut 11, the power storage element 12, the state transition unit 13, and the communication module 14 inclnding the MPU 107 10 are mo~utted on the substrate 210. In FIG. 12, for the sake of convenience of description, the housing 201 can be divided in two, but the housing 201 tilay be integrally molded not to be divided. [OlOO] As illustrated in FIG. 13, the respective components of the module 20a are 15 accommodated in a housing 202 having the same shape of tlie Iiousing 201. The respective components of the module 30a are acconnmodated in a housing 203 having the same shape of the housing 201. The respective components of the module 40a are accommodated in a housing 204 having the same shape of the housing 201. In other words, in this example, the electronic device 1 includes the 20 housings 201,202,203, and 204 in \vhich the respective components of the modules are accon~modated. [OlOl] For example, by connecting the housings 201, 202, 203, and 204 in a circle using a lace or a chain and putting them around the neck of the user, the electronic 25 device 1 can he used like a necklace. Further, by connecting the housings 201,202, 203, and 204 using a circular band, the electronic device 1 can be used like a wristband. By further reducing the liousings 201, 202, 203, and 204 in size and attaching the downsized housings to a ring-like nietallic member, the electronic device 1 can be used like a ring. Of course, these use forn~sa re exatilples and are 30 not limiting. [O 1021 Further, an arrangement position of tlie power generating unit in the housing may be set according to characteristics of the power generating nnit. For example, wheu the power generating uuit is the solar power generating unit, it is desirable to arrange the solar power generatittg unit at a surface side of the inside of the housing 5 so that lights falls on tlie solar power generating unit. For example, when the power generating unit is the vibration power generating unit, it is desirable to arrange the vibration power getierating unit near tlie center of the inside of the housing in order to reduce influence of noise. For example, when tlie power ge~~eratin~gm iti s configured wit11 a piezoelectric element, it is desirable to arrange the piezoelectric 10 element at the surface side of the inside of the housing. [0 1031 The function of the electronic device 1 can be extended, for example, using an exteusion module. As illustrated in FIG. 14, an extension module includes a 15 housing 205 having &e same shape as the housing 201, for example. A configuration for implementing the extension niodule is accommodated in the housing 205. [O 1041 For example, by arranging a memory and a driver for performing a 20 recording and reproducing process on the memory in the housing 205, it is possible to cause the extension module to function as a storage device. For example, by arratlging an electronic paper or the like in the housing 205, it is possible to cause the extension modnle to fi~nctioua s a display. For example, by installiug a switch or a button on the surface of the housing 205 and electrically connecting tlie housing 205 25 with the respective modules, it is possible to cause the extension modnle to furlctio~i as a device that supplies some triggers to the respective modules. [0105] For example, by arranging a clock generating device in the housing 205 and electrically connecting the l~oousing2 05 with the respective modules, it is possible to 30 cause tlie extension module to function as a device that provides a clock to the respective niodules. For example, by installing an MPU in the housiug 205 and electrically connecting the llousing 205 with the respective mod~~leist ,i s possible to cause the extension 11lodule to function as a control device that controls the respective n~odules. [0 1 061 5 For exanlple, by arranging a battery cell in the housing 205, it is possible to cause the extension nlodule to fi~nctiona s a battery cell that supplies electric power to the respective modules. For example, by arranging a configuration imnplementing a clocking fi~nctiona nd a display function in the housing 205, it is possible to cause the extension module to filnction as a clocking device. For example, by arranging a 10 speaker in the housing 205, it is possible to cause the extension nlodule to fi~nctiona s a speaker device. The extension module majr be configured as a universal serial bus (USB) memory. For example, by forming a terminal of a predeter~l~inesdh ape in the housing 205, it is possible to cause the extension module to function as a terminal for connecting the electronic device 1 with another device. 15 [0107] For example, the inside of the housing 205 may be hollow or may be filled with resin or the like. It is possible to cause the extension module to function as an adjustr~lenmt ember for adjusting the size of the electronic device 1 to be suitable for the size of a neck or a hand, for example, when a plurality of n~odulesa re connected, 20 and the electronic device 1 is used as an accessory. As described above, the electronic device 1 may be configured to include the extension module in addition to the modules. Further, a plurality of extension ~llodules may be used in the electronic device 1. [0108] 25 By arranging a comnlunication n~odulea nd a power source for driving the co~llmunication illodale in the housing 205, it is possible to cause the extension module to function as a main connnunication module. The term "main" in the main cotnmunication module is an expression for co~lvenienceo f description to distinguish it from the communication module in the module 10a or the like, and it does not have 30 a special meaning. [0 1091 As illustrated in FIG. 15, for example, the respective modules (the nodule 10a, the module 20a, the tnodule 30a and the nodule 40a) and the maill co~mnunicationtn odule (referred to appropriately as a "main co~n~nu~iicatmioord~ul e 50") perform wired or wireless communication with one another. For example, 5 NFC of several tens of centimeters is performed. Each of the modules transmits the allocated identifier or the like to the main communication module 50 as the state transition unit transitions to the ON state. The main communication module 50 transmits information of the identifier received froom the modules to an external device such as the smartphone SH. 10 [OllO] As described above, the co~nmu~~icatwiointh the external device may be performed through the main communication module. Here, an example of a co~umunications ystem const~uctedb y the electronic device and the external device will be described. In the above description, in order to facilitate a description, an 15 illustration of the power storage element, the state transitiotiunit, and the like will appropriately be omitted. [Olll] FIG. 16 is an example of a commu~lication syste~il constructed by the electronic device 1 and an external device AU. The example illustrated in FIG. 16 20 is an exa~nplec orresponding to the above embodiment, and the main comtnunication module is not used. In other words, the example illustrated in FIG. 16 is an example in which the con~municatiom~~od ule of each module independently perfornls co~ilmunicationw ith the external device AU. [0112] 25 FIG. 17 illustrates another example of the conimunication systetn constructed by the electronic device 1 and the external device AU. The example illustrated in FIG. 17 is an example corresponding to the cotntnunication system described with reference to FIG. 15. Each module transmits the identifier of the module or the like to the 1nai11c o~lin~~nicat~ioinlo d~5l0e t1110ugIi NFC. 'rhe main 30 communication inodule 50 transmits inforinatiot~r eceived fro111 the modules to the external device AU. Since it is desirable that the co~nrnu~licatmioo~d~u le of each module pcrfornl, for example, NFC, the size of the conl~nu~iicationnl odule or the atitelula can be reduced. Further, since energy consumption for a series of cotnmunication operations is suppressed, a communication frequency can be increased. This corresponds to an itnprovement in sensitivity in sensor and 5 tenlporal resolution, for exanlple. Since the main conln~unicationm odule 50 needs a certain size but does not need a power generating unit or tlie like, it is possible to prevent the main cotn~nunicatiom~o~d ule 50 from being increased in size. [0113] Further, the power generating units in the electronic device 1 tnay be 10 grouped, and a conimunication module may be installed for each group. For example, the solar power generating unit 11 of the module 10a and the temperature difference power generating unit 21 of the module 20a are grouped as illustrated in FIG. 18. A com~nuuicationm odule (a conununication module 60) corresponding to the group is installed. In other words, tlie n ~ o d ~1~0lae an d the module 20a share tlie 15 co~nmunication module 60. The present embodilllent is not limited to the cotnmunication module, and one state transition unit corresponding to the group Inay be installed. [0114] In the example illustrated in FIG. 18, for example, it is necessary to check 20 whether the communication nodule 60 is being used by perforn~ingc ommunication between tlie MPU of the module 10a and the MPU of tlie module 20a. For example, the MPU of the tnodule 1Oa inquires to the MPU of the module 20a whether the cotn~nunicationm odule 60 is being used. Here, wvhen the state transition unit of the module 20a is in the OFF state, and the MPU is not in an activated state, there is no 25 response to the inquiry. Thus, the MPU of the module 10a controls the comtnunication module 60 such that the identifier allocated to the module 10a or the like can be transmitted to the external device AU. [0115] Further, as illustrated in FIG. 19, a co~mnunicationm odule (for example, the 30 communication tnodule 60 in FIG. 18) shared by a plurality of modules may perfornl cotnn~unicationw ith the main co~n~nunicationnio dulc 50. For exanlple, NFC may be perfonned between tlie cotn~nunication module 60 and the niain commu~~ication module 50. [OI 161 Fu~the~as; illustrated in FIG. 20, the conununication module of each module 5 may be configwed to function as a main comnlunication system according to circumstances. For example, the co~nmunicationm odule of the module having the power generating unit having the largest power generation amount is allocated as the main connnunication module. For exaniple, the power generation amount is specified by any one of a voltage, an electric culuent, electric power and electric 10 energy or a co~nbination thereof. Comnunication is performed betweeti the communication module decided as the main cotnniunication module and atiotlier communication module. The niain conxnunication nlodule transmits inforniation received from another communication module to the external device. [0117] 15 I11 the configuration of the co~nmunications ystem illustrated in FIG. 20, it is necessaly to monitor the power generation atnount of each power generating unit. To this end, for example, it is desirable to monitor the power generation amount of the power generating unit atid itistall an extension module (a control. device) that controls whether any one cotn~nunication module functions as tlie main 20 communication module according to the tnonitoring result. However, it is unnecessary to install the main coniniunicatio~i module as the extension module. The example of tile conxnunication system is not limited to the exemplified exatnple atid can be appropriately changed. [0118] 25 4. Application examples> Next, application exatnples of tlie electronic device will be described. Of course, content of the present disclosure is not liniited to application examples which will be described below. [0119] 30 As illustrated in FIG. 21, the electronic device 1 (the electronic device 2 or the electronic device 3) outputs predetermined inforriiation to a second electronic 33/63 device tluough cotnmunication or the like. For esa~nple, the predcter~nined infornlation is the identifier allocated to each module or the time infor~nation. The second electronic device includes a receiving unit that receives the predetermined information transtnitted from the electronic device 1 as an example of an acquiring 5 unit. The second electronic device generates various information based on the predetermined infor~nationtr ansmitted from the electronic device 1. [O 1201 Examples of the second electronic device include a game machine G, a health management device H, and an analysis device. For exan~ple,t he analysis 10 device is a position infornlation identification device P. The electronic device 1 may perform communication wit11 the second electronic device via a relay device (a third electronic device) such as a smartphone. For example, the second electronic device already has information about a configuration of a power generating unit arranged in a module corresponding to the identifier. For this reason, for example, 15 when the identifier of the module 10a is transmitted from the electronic device 1, the second electronic device can recognize that the solar power generating unit 11 of the module 1Oa has generated a predetermined amount or more of electric power. [0121] 20 First, an application example of a game systetii in which the second electronic device functions as the game nlachine G will be described with reference to FIGS. 22A to 22D. The gatlie machine G includes a control device such as a central processing unit (CPU) for implementing a function described below, a storage device that stores the number of receptions of the identifier of the module during a 25 certain period of time, and the like. In this example, the game device may be a device having a game function such as a smartphone serving as an exatnple of the relay device. In FIG. 22A to FIG. 22D, a bar graph schetnatically indicates a pattern of the number of receptions of the identifier of the n~odule. [O 1221 30 In an example illustrated in FIG. 22A, the nutnber of receptions of the identifier of the module 10a including the solar power generating unit 11 is largest, and the number of receptio~ls of the identifier of the nodule 30a including the vibration power generating unit 31 is next largest. Thc ~lu~nboefr receptions of the identifier of the module 20a including the temperature difference power generating unit 21 is a predetern~ined number of times, and the nu~nber of receptions of the 5 identifier of the module 40a including the radio wave power generating unit 41 is smallest. [0 1231 In an example illustrated in FIG. 22B, the number of receptions of the identifier of the module 10a including the solar power generating unit 11 and the 10 number of receptions of the identifier of the module 30a including the vibration power generating unit 31 are large. The number of receptions of the identifier of the rnodule 20a including the temperature difference power generating unit 21 is large as well. The number of receptions of the identifier of the module 40a including the radio wave power generating unit 41 is also the predetermined number 15 of times or more. [0 1241 In an example illustrated in FIG. 22C, the number of receptions of the identifier of the module 10a including the solar power generating unit 11 and the number of receptions of the identifier of the module 30a including the vibration 20 power generating unit 31 are small. The nuulber of receptions of the identifier of the module 20a including the temperature difference power generating unit 21 and the nunlber of receptions of the identifier of the module 40a including the radio wave power generating unit 41 are the predetermined number of times or more. [0125] 25 In an example illustrated in FIG. 22D, the number of receptions of the identifier of the module IOa including the solar power generating unit 11 and the number of receptions of the identifier of the nodule 30a including the vibration pomrer generating unit 3 1 are the predetermined number of times or more. On the other hand, the number of receptions of the identifier of the module 20a including the 30 tenlperature difference power generating unit 21 and the number of receptions of the identifier of the module 40a including the radio \vaxle ponrer generating unit 41 are larger than the aumber of receptions of the identifier of the nlodtlle 10a. [0 1261 The game maclii~~Ge analyzes behavioral characteristics of the user of the electronic device 1 using this information. For example, in the case of the pattern 5 of FIG. 22A, since the ~iumber of receptions of the identifier of the module 10a is large, the solar power generating unit 11 frequently generates electric powel: In other words, the user of the electronic device 1 is inferred to have an outdoor activity. On tlie other hand, since the number of receptions of the identifier of the lllodule 40a is small, the radio wave power generating unit 41 generates little electric power. In 10 other words, the user of the electronic device 1 is inferred to have an activity in a region (for example, a mountain) which a radio wave hardly reaches. [0127] Meanluhile, sirice the number of receptions of the identifier of the module 20a and the number of receptions of the identifier of the module 30a are at a norn~al 15 level, the temperature difference power generating unit 21 and the vibration power generating unit 3 1 generate a normal level of electric po\ver. In other words, the user is inferred to have an activity such as walking. Thus, in tlie case of the pattern of FIG. 22A, a behavioral characteristic of "frequently enjoying outdoor activities" is determined. 20 [0128] In the case of the pattern of FIG. 22B, since the nunlber of receptions of tlie identifier of the module 10a is large, the solar power generating unit 11 frequently generates electric power. I11 other words, the user of the electronic device 1 is inferred to have an outdoor activity. Further, since the nutnbcr of receptions of the 25 identifier of the nmddule 20a and the number of receptions of the identifier of the module 30a are also large, the temperature difference power generating unit 21 and the vibration power generating unit 31 frequently generate electric power. In other words, the user of the electronic device 1 is inferred to have a vigorous activitj~. Thus, in the case of the pattern of FIG. 22B, a behavioral characteristic of "frequently 30 taking part in spoi-ts" is determined. [0 1291 In the case of the pattern of FIG. 22C, since the number of receptions of the identifier of the module 10a and the number of rcceptions of tlie identifier of the niodule 30a are small, the solar power generating unit 11 and the vibration power generating unit 31 generate little electric power. In other words, the user of tlie 5 electronic device 1 is inferred to stay indoors and not to have a vigorous activity. Thus, in the case of the pattern of FIG. 22C, a behavioral characteristic of "often staying indoors" is determined. [0130] In the case of the patten1 of FIG. 22D, since the number of receptions of the 10 identifier of the module 20a is slightly large, the temperature difference power generating unit 21 generates electric power. It1 other words, the user of the electro~~dicev ice 1 is inferred to Ilave a slightly vigorons activity. Furthel; since the number of receptions of the identifier of the module 40a is large, the radio wave power ge~leratingu nit 41 frequently generates electric power. In other words, the 15 user of the electronic device 1 is inferred to stay in a place (for exatnple, an urban area) which a radio wave reaches well. Thus, in the case of the pattern of FIG. 22D, a behavioral characteristic of "freqoently having fun on the town" is deternlined. [0131] The game machine G generates information related to a game, such as 20 characters used in a game, based on the determined behavioral characteristic. For example, \vlen the behavioral characteristic of "frequently enjoying outdoor activities" is determined, for example, a "character living in a mountain" brining an outdoor activity to mind is generated by reflecting the behavioral characteristic. For example, when the behavioral characteristic of "frequently taking part in sports" is 25 detennined, for exanlple, a "character of a tough \varriorU is generated by reflecting the behavioral cl~aracteristic. [0132] For esanlple, when the behavioral characteristic of "often staying indoors" is determined, for example, a "cllaracter of an intelligent magician" brining an image 30 of enjoy studying or acquisition of kno\vledge to mind is generated by reflecting the behavioral characteristic. For example, when the bellavioral characteristic of "frequently having fi~no n the towvn" is determined, for cxample, a "character of a nlischievous elf' brining a character liking to play to tnind is generated by reflecting the behavioral characteristic. [0133] 5 The game machine G is set so that the generated character can be used in the gatne. Tlie game machine G may transniit data of the generated character to a snla~tplloneo f the user or the like. As described above, it is possible to generate the infomnlation related to the game using the infornlation transtilitted from the electronic device 1. Further, the information may be used for an avatar of an application or 10 the like other than a game. [0134] Next, an example in which the electronic device 1 is applied to a health management system will be described with reference to FIGS. 23A to 23D. The 15 electronic device 1 transmits the information such as the identifier of the module to the health management device H. The health management device 1-1 includes, for example, a control device such as a CPU for implementing a fut~ction described below. The health management device H generates information related to health, for example, advice contributing to health management using the predetermined 20 information transmitted from the electronic device 1. [0135] FIG. 23A illustrates an exatnple of a change in the number of receptions of the identifier of the nlodule 10a during one day. Tlie number of receptions is set to, for example, five levels, and the respective levels are indicated by different hatchings. 25 A time zone indicated by a high level hatching indicates that the number of receptions of tlie identifier of the module 10a is large. As illustrated in FIG. 23A, the number of receptions changes to a relatively high level from about 8:00 am to the evening. The health management device H atialyzes that the solar power generating utiit 11 frequently generates electric power since the user of tlie electrotiic device 1 30 frequently goes out based on tlie change in the number of receptions. The health lnanagenlent device H generates advice for health matlagenlent according to the analysis result. For exanlplc, the health ~nanagement device H gellerates the advice of "be careful about ultraviolet rays." [0136] FIG. 23B illustrates an example of a change in the iiu~nbero f receptiolls of 5 the identifier of the module 20a during one day. A time zone indicated by a high level hatching indicates that the number of receptions of tlie identifier of the niodule 20a is large. As illustrated in FIG. 23B, in the morning and the evening, the number of receptions changes to a relatively high level. The health nianageme~lt device H analyzes that the temperature difference power generating unit 21 generates electric 10 power since the user of the electronic device 1 comes and goes between the outdoors and indoors in which there is a big tetiiperatnre difference to commute or study during the summer or the winter based on tlie change in the nnlllber of receptions. The health nlanagement device H generates advice for health management according to the analysis result. For example, tlie health management device H generates the 15 advice of "be careful about body tenlperature adjustment." [0137] FIG. 23C illustrates an example of a change in the nntnber of receptions of the identifier of the module 30a during one day. A time zone indicated by a high level hatching indicates that the number of receptions of the identifier of the module 20 30a is large. As illustrated in FIG. 23C, excluding a period from the night to the moniing, the number of receptions changes at a relatively high level. The health nianagetnent device 1-1 analyzes that the vibration power generating unit 31 frequcr~tlyg enerates electric power since the user of the electroi~icd evice 1 takes pal? in vigorous activities based on the change in the ~lunlbero f receptions. The health 25 management device H generates advice for health manageme~it according to the analysis result. For example, the health ri~anagementd evice H generates the advice of "let's take a rest." [0138] FIG. 23D illustrates an exainple of a change in the ~lu~nboefr receptions of 30 the identifier of the module 40a during one day. A time zone indicated by a high level hatching indicates that the iiutilber of receptions of the identifier of the nlodule 40a is large. As illustrated in FIG. 23D, the g number of receptions changes at a relatively lug11 level during daylight. Thc health tnarlagemeut device 1-1 analyzes that the radio wave power gellcratii~g unit 41 frequently gcnerates electric power using a radio wave generated from a personal computer since the user of the 5 electronic device I works on the personal computer during daylight based on the change in the number of receptioas. The health matlagelllent device H generates advice for health management according to the analysis result. For exatnple, the health management device H generates the advice of "let's relax eyes." [0139] 10 For example, the health management device H transmits the generated advice to an address of an e-mail which is registered in advauce. The user cat1 get the advice for health managemet~t. The advice generated by the health management device H may be transmitted to the user by mail or the like. [0 1401 15 Next, an example in which the electronic device 1 is applied to the authentication system will be described. For example, the authentication system includes the electronic device I, an authentication information determination system Y, and a key Z that is at least one of a physical key and a logical key. The 20 authentication information determination system Y it~cludesa control device such as a CPU for implementing a fi~nctiorld escribed below. The electro~~idce vice 1 generates at least one of ide~~tificatioinllf ormation identifying an individual on which the electronic device 1 is mounted or installed and identification information identifying a group serving as a set of individuals on which the electronic device 1 is 25 rnouuted or installed. [0141] The authentication infom~atiorld etermit~ations ystem Y includes a database. The database stores a feature of information identifying an itldividual transmitted fron~th e electronic device 1 for each individual, each group, or each condition. For 30 example, as described above it1 the example of the health management system, according to an' enviroru~~ein~ ~\vth ich a target (referred to appropriately as a "tnouating/i~~stallationta rget") on \vhicli the electronic device 1 is mounted or installed is placed, the electronic device 1 indirectly generates infor~nationi ndicating a feature of the ~mou~iting/installatiotna rget. In other words, even though it is sufficie~lot r insufficient in defining information specifying the ~uounting/installatiotl 5 target or a specific condition to be satisfied, information generated fiom various kinds of energy which the electronic device 1 obtains from the surrounding environtnent of the tnounting/installatiorl target as effective information, is used as authentication infornlation A. [0 1421 10 Further, by intentiotially applying input energy to the electronic device 1 through the tno~mting/installationt arget using a certain pattern, it is possible to cause the electronic device 1 to generate information specific to the mounting/installation target. In other words, for example, it is possible to intentionally generate feature information by repeating an action of blocking sunlight from reaching the electronic 15 device 1 that generates information when receiving sunlight during a certain period of time at a certain timing with a hand. This feature quantity can be used as information that can be detected by only the mounting/installation target that has generated it or information defining a certain condition to be satisfied. Thus, even though it is sufficient or insuficient in defining information specifying the 20 mo~~nting/installatitoa~rgl et or a specific condition, information which the electro~c device 1 generates as effective information is used as authentication information B. [0 1431 The authentication irlfornlation A, the authentication information B, or a combination of the authentication infornlation A and B may be stored in the database 26 as authentication infonnation. Fui?l~er, as the infoilnation specifiing the mounting/installation target or the information defining a specific condition to be satisfied, a cornbination of infortuatiou that is not generated by the electronic device 1 and infornlation that is generated by the electronic device 1 may be used. In other words, there is a featnre quantity specific to the nlounting/installation target, for 30 example, a physical feature quantity (a fingerprint, a voiceprint, an iris, a vein, DNA, a contour of a face or a body, or the like) in the case of a human being, ID infortnation such as a character string, itlforlnation related to an interest or a preference, and the like, and a combination of authentication infortnation C obtained therefrom and either or both of the authetlticatio~iln fortnation A and B obtained from the electronic device 1 cat1 be used as authentication inforn~ationD . 5 [0144] For example, one or tnore of the aothelltication information A, B, C, and D is registered in the database tvitli ~vhichth e authentication information deterlnination system Y is- equipped, and by comparing the registered authentication information with the information generated by the electronic device 1 or additional infor~nation 10 generated fiom the inforniation generated by the electronic device 1, tlie physical or logical key z opens or closes. [O 1451 A form of the key Z is not consequential, for example, the key Z may be a door that is pl~~~sicalollcyk ed, a contact point that is locked by an electric signal or 15 the like, a variable used for access control from a certain program to another Fogram, or the like. As a more specific example, when an attribute value, an occupation, or tlie like is allocated to the mounting/installation target through information from the electronic device I mo~intedo r installed on the n~our~tin~installattiaorng et as it1 the application example of the game system, a zone on a game program which only a 20 certain specific attribute or occupation is allowed to enter may be set, and entrance may be limited in a real space other than a game program. [0146] Further, for example, a bracelet-like accessory form made by partially using tlie electronic device 1 may be used to change according to a specific condition, for 25 example, such that a vibration/motion power generation device installed in the electronic device 1 generates electric power in a specific power generation pattern, for example, by rotating the accessory, and a fortn in which power generation based oti sunlight is performed once or tnore per second or a color is changed. It may be used for controllitlg the ~llo~uititig/installatiot~alr get, for exatnple, an event intended 30 only for the mounting/instailation target satisfying a specific co~iditioti may be performed. As in the application exanlplc of the health manage~nent systenl, a health condition of the mounting/installation target nlay be detected according to information from the electronic device 1 mounted or installed on the 5 mounting/installation target. Then, grouping tilay be perfornled according to the health condition of the niounting/i~istallationta rget, and, for example, an access zone of a l~ospital ward may be classified according to the group, or an accessible nledicine case may be controlled according to the group. [0148] 10 Next, an exaniple in which the electronic device 1 is applied to the position inforniation identification system wil be described. The position infonnation identification system includes, for exatnple, the electronic device 1 and a position inforniation identification device P. The position information identification device 15 P includes a control device such as a CPU for iniplementitig a fitnction described below. [0 1491 The position information identification device P includes a database. The database stores a feature of information transmitted from the electronic device 1 for 20 each region. For exanlple, a region A is assunled to be a region in which the weather is nlostly fine, a teniperature difference is small, and reception of a radio mrawre is not fine. In this region, since the solar power generating unit 11 frequently generates electric power, the number of receptions of the identifier of the module 10a tends to be large. On the other hand, since the temperature difference power 25 generating unit 21 arid the radio ws7ave power generating unit 41 generate little electric powel; the number of receptions of the identifiers of the module 20a and the module 40a tends to be stiiall. [0150] Further, for example, a region B is assunled to be a region in which the 30 weather is mostly rainy, a temperature difference is large, and a road is chaotic. In this region, since the solar power generating unit I I generates little electric power, the ntunber of receptions of the identifier of the module 1Oa tends to be snlall. 011 the other hand, since the tetnpcrature difference power geiierating unit 21 and the vibration power generating unit 31 are likely to generate a relatively large amount of electric power, the number of receptions of the identifiers of the tnodule 20a and the 5 module 30a tends to be large. [0151] The position inforlnation identification device P searches for a region having a tendency which is identical or similar to the tendency of the number of receptions of the identifier of the module transmitted from the electronic device 1 10 from information accumulated in tlie database. Then, a region in which the electronic device 1 is located is determined based on the search result. [0152] Information usable in a plurality of websites may be generated according to 15 predetermined information transmitted from the electronic device 1. Furthel; information related to a power generation capacity of the power generating unit may be generated. For example, demonstration data indicating an amount of electric power that can be generated by the solar power generating unit, the radio wave power generating unit, or a newly developed power generating unit may be generated. 20 For example, the demonstration data may be provided to a company that has developed the power generating unit or an electric utility conlpan). [0153] Further, secondary information obtained by estimating a power generation capacity (an electric energy, average electric powel; an average voltage, or tlie like) 25 of the power generating unit of the module may be generated using the number of receptions of the identifier of the module or a reception time interval. Furthermore, tertiary inforliiation such as an at~~ouonft sunlight when the poltier generating init of the nlodule is the solar power generating unit, a temperature or a ~netabolicc alorie when the power generating unit of the module is the temperature difference power 30 generating unit, acceleration or mom en tun^ when the power generating unit of the tnodule is the vibration power generating unit, or radio wave strength when the power generating unit of the module is the radio waxre power generating unit may be generated using the secondary infom~ation. [0 1 541 Instead of the number of receptions of the identifier of the module, the 5 identifier of the module and the time infor~llation transnlittcd from the electronic device 1 may be used. The game machine G or the like can deternline that the power generating unit of the module frequently generates electric power when the interval of the time information is short. [0155] 10 <6. Modified examples> The embodiments of the present disclosure have specifically been described, but the present disclosure is not limited to the above embodiments, and various kinds of modifications can be made based on the technical spirit of the present disclosure. [0 1.561 15 In the above embodiments, the state transition unit of the electronic device is configured to cause the state to transition based on the electric energy, but the etnbodinnent is not limited thereto. The state transition unit causes the state to transition based on different energy (a first energy) from electric energy. In this case, the first energy is converted into electric energy sewing as an example of a 20 second energy, the state of the state transition unit transitions, and then electric energy is supplied to an output unit (for example, the co~nnlunicationm odule). The output unit outputs the predetermined information to an external device using the supplied electric energy. A specific example of the predeter~nined information has been described above in the first enlbodiment, and thus a duplicate description will 25 be omitted. [0 1571 FIG. 24 illustrates an exanlple of a configuration of a nlodule (referred to appropriately as a "tnodule 10d") of the electronic device according to a modified example. In FIG. 24, the flow of the first energy is indicated by a dotted line, and 30 the flow of the second energy or a signal or a co~llnlandb ased on the second energy is indicated by a solid line to be distinguished. The same conlponents as those in the module 10a are denoted by the same reference numerals, and a duplicate description will appropriately be omitted. [0158] The 111odule 10d includes a thermal storage unit 250 that accu~llulates 5 thermal energy serving as an example of the first energy, a power generating unit 251 serving as an example of a com~erting[ unit, and a bimetal 252 senling as an example of a state transition unit. The module 10d further inclodes an MPU 107, a storage unit 108, and a connnunication modole 109. [0159] 10 The thermal storage unit 250 accu~~lulatethse thermal energy, and sopplies the thermal energy to the power generating unit 251 and the bimetal 252 at an appropriate timing. The power generating unit 251 is a device that converts the thermal energy supplied fronl the thermal storage unit 250 into electric energy, and a know~7n device may be applied. The bimetal 252 is a switch that is configured with a 15 bimetal obtained by joining metals having different thermal expansions and a contact point, and supplies or interrupts electricity as the bimetal expands due to a temperature change to operate the contact point. For example, the bimetal 252 transitions between two states of ON and OFF, arid when the bimetal 252 is in the ON state, the bimetal 252 is electrically connected to the MPU 107. 20 [0160] An example of an operation of the module 10d will briefly be described. Though a thermal storage operation of the thermal storage unit 250, the thermal storage unit 250 accumt~latest he thernlal energy. The thermal energy is supplied from the thermal storage unit 250 to the power generating unit 251 and the bimetal 25 252. The power generating unit 251 generates electric power by converting the supplied thermal energy into electric euergy. The temperature of the bimetal 252 increases according to the supplied thermal energy, and a state in which the temperature thereof becomes a predetermined temperature or more is the ON state. As the bimetal 252 enters the ON state, the bimetal 252 is electrically co~~nectetdo 30 the MPU 107. [0161] 'fie bi~netal 252 may be used for ON/OFF s\vitcl~ingo f a tl~eenalc ontact point instead of ONIOFF switching of an electric contact point. In other words, wl~enth c bimetal 252 enters the ON state with the increase in the telnperature of the tl~ermal storage unit 250, the bimetal 252 is thermally connected to the power 5 generating unit 251, and the ther~nal energy is conducted from thc tl~eennal storage unit 250 through the bimetal 252. The power generating unit 251 may be configured to generate electric power according to the inflow ther~nale nergy at this time. [0 1621 10 As the bimetal 252 is electrically connected to the MPU 107 or as the power generating unit 251 is directly connected to tlie MPU 107, the electric power generated by the power generating unlit 251 is supplied to the MPU 107. The MPU 107 supplies tlie electric power to the storage unit 108 and the commut~icatio~i module 109, and perfortns control such that the communication module 109 15 performs a predetermined operason. The communication module 109 operates according to the control by the MPU 107, and the conununication module 109 transmits, for example, the identifier of the module 10d to an external device. A power storage element such as a capacitor may be installed between the MPU 107 and either the bimetal 252 or the power generating unit 251, and the electric power 20 generated by the power generating unit 251 may be stored in the power storage element. [0 1631 Another example will he described. FIG. 25 illustrates an example of a configuration of a module (referred to appropriately as a "modale 10e") of the 25 electronic device according to a modified example. In FIG. 25, the flow of the first energy is indicated by a dotted line, and the flow of the second energy or a signal or a cotnrnatid based on the second energy is indicated by a solid line to be distinguished. The same co~nponentsa s those in the inodule 10a are denoted by the same reference nu~ileralsa, nd a duplicate description will appropriately be omitted. 30 [0164] Tlie module 10e includes a spiral spring 300 and a power generating unit 301 serving as an example of a converting unit. The nlodule 10e furtl~erin cludes an MPU 107, a storage unit 108, and a communication nlodule 109. The spiral spring 300 functions as a power storage unit that accumulates kinetic energy applied from the outside and functions as a state transition unit that transitions between a state in 5 which the accun~ulated kinetic energy is accunlulated and a state in wvllich the accumulated kinetic energy is released. The state in which the kinetic energy is accunlulated refers to, for example, a state in which the spiral spring 300 is sufficiently wound up, and the state in which the kinetic energy is released refers to, for example, a state in wl~ich the wvoutd spiral spring 300 perfornls a rewinding 10 operation. Further, for example, vibration of the user wearing the electronic device 1 is supplied to the spiral spring 300 as the kinetic energy. [0 1651 Tl~epo wer generating unit 301 is, for example, a mechanism that includes a magnet and a coil and performs electromagnetic induction power generation. As 15 one of the magnet and the coil of the power generating unit 301 rotates according to the kinetic energy supplied from the spiral spring 300, electric power is generated. The electric power generated by the power generating unit 301 is supplied to the MPU 107. [0166] 20 An example of an operation of the module 10e will briefly be described. Througl~th e vibration of the user or the like, the spiral spring 300 is wound up, and the kinetic energy is accumulated in the spiral spring 300. Then, after the spiral spring 300 is sufficiently wound, the spiral spring 300 enters the release state, and thus the kinetic energy is supplied to the power generating unit 301. Due to the 25 kinetic energy supplied by the spiral spring 300, for example, the magnet of the power generating unit 301 rotates, and the power generating unit 301 generates electric power. The electric power generated by the power generating unit 301 is supplied to the MPU 107. [0 1671 30 The MPU 107 supplies the electric power to the storage unit 108 and the communication lnodule 109, and performs control such that the co~nnn~nication module 109 perfortns a predetentnined operation. The commn~~nicatiotnn odule I09 operates according to the control by the MPU 107, and the co~~~municatiilo~no dule 109 transmits, for example, the identifier of the module 10e to an ester~iald evice. Further, a power storage element such as a capacitor may be installed between the 5 power generating unit 301 and the MPU 107, and the electric power generated by the power generating unit 301 may be stored in the power storage element. [OI 681 In addition to the above examples, a light storage material that accumulates optical energy may be used as an element that stores energy in a non-electric form. 10 In this case, an ,energy co~lverting device that converts optical energy into electric energy is used. [O 1 691 In the above embodiments, when the state transition unit transitions to the ON state, the identifier of the module or the like is transmitted to the external device, 15 but only the recording process may be perfornled by the MPU when the state transition unit transitions to the ON state. For exanlple, the number of times in which the state transition unit transitions to the ON state is stored in the storage unit of the electrot~icd evice. For example, the information stored in the storage unit of the electronic device is output to a persor~al computer when the electronic device is 20 connected to the personal computer. [0 1701 The present disclosure may be implemented by a method, a program, a system, or the like without being limited to a device. For example, the program may be provided to the user via a network or a portable memory such as an optical 25 disk or a setniconductor menlory. [0171] In this case, a form of the progiam is not consequential as lo11g as a function of the program is inlplemented, for exa~nple,t he program may be an object code, a program executed by an interpreter, script data supplied to an OS, or the like. As a 30 method of supplying a progratn using wired or wireless co~mnunication,a method of storing a computer progratn for i~nplementingc ontent of the present disclosure or a data file (a program data file) serving as a computer program for inlplen~enting contellt of the present discloswe on a clicnt cotuputer such as a con~pressed file with an auton~atic installation fi~nction in a server on a computer network and do~vnloadingth e program data file to a co~ulectedc lient conlputer may be used. In 5 this case, the program data file may be divided into a plurality of segment files, and the seg~nenfti les nlay be arranged in different servers. [0 1721 The configurations and the processes of the e~~~bodirl~aennd ttsh emodified examples nlay be appropriately combined within the scope in which no technical 10 contradiction occurs. The order of the processes in the flow of the process may be appropriately co~nbinedw ithin the scope in which no technical contradiction occurs. [0 1731 The present disclosure can be applied to a cloud system in which the abovedescribed processes are distributed and performed by a plurality of devices. The 15 present disclosure can be implemented as a device in which at least some of the above-described processes are performed in a system in which the above-described processes according to the embodiments and the modified example are performed.
