Description:TECHNICAL FIELD
[0001] The present disclosure relates to the field of wearable fitness devices. In particular, the present disclosure provides a wearable device for automatic stress monitoring of a user.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed disclosure, or that any publication specifically or implicitly referenced is prior art.
[0003] Stress is a person’s physiological, emotional and psychological response to events of trauma, fear and hypertension. Undiagnosed stress can lead to severe health complications related to heart and psychological well-being. Hence regular stress monitoring is essential. Health monitoring at diagnostic clinics is difficult to be performed with guaranteed regularity due to multiple reasons like time management, prior commitments, work related matters, unavailability of diagnostic machines and/or technicians, inability of the patient to go out and the likes. Therefore it would be beneficial to develop a wearable system or device that can perform health monitoring sustainably and at an affordable cost.
[0004] Existing literature includes description of a wearable apparatus for measuring stress. Another disclosure deals with a measuring unit and method for measuring stress index of a user based on sensing of biological attributes. A wearable and flexible wristband with one or more biosensors and information transmission facility has also been disclosed. A smart watch having fitness monitoring features have been introduced to capture one or more physiological parameters of a user and wirelessly communicate with external devices for storage of said parameters. However, electrodermal activity (EDA) sensing from sweat has not been discussed in any of the disclosures.
[0005] Hence there is need in the art to develop a wearable device that can measure skin conductivity using an EDA sensor in addition to measurement of bioimpedance, skin temperature, heart rate and oxygen saturation level. The proposed device is portable, low cost, accommodates one or more sensors for monitoring of physiological attributes and is configured to determine one or more stress indicators. The device has remote operability, storage, input receptive, displaying and recalling features that are necessary to generate a health map of the user over a predetermined time span in addition to instant viewing.

The interface(s) (206) may also provide a communication pathway for one or more components of the controller (108). Examples of such components include, but are not limited to, memory (204) and the database (222).

In examples described herein, such combinations of hardware and programming may be implemented in several different ways.

In the present examples, the machine-readable storage medium may store instructions that, when executed by the processing resource, implement the processing engine(s) (208). In such examples, the controller (108) may comprise the machine-readable storage medium storing the instructions and the processing resource to execute the instructions, or the machine-readable storage medium may be separate but accessible to the controller (108) and the processing resource. In other examples, the processing engine(s) (208) may be implemented by electronic circuitry.
[0054] In an embodiment, the processing engine (208) may include a physiological parameter determination unit (210) that may be configured to receive a first set of input signals from the one or more sensors (102). The one or more processors (202) may be enabled to extract a first set of data packets pertaining to physiological parameters of the user from the received first set of input signals. The first set of input signals may be any or a combination of voltage signal, current signal, resistive signal, capacitive signal, inductive signal and the likes. By way of example, the physiological parameters represented by the first set of data packets may include any or a combination of skin temperature, blood pressure, bioimpedance, electrodermal activity, hydration level of body, oxygen saturation in blood vessels and the likes.

[0057] In an embodiment, the processing engine (208) may include a comparison (214) that may be configured to receive the first set of data packets and compare, the first set of data packets with a second set of data packets. The one or more processors (202) may correspondingly generate a third set of data packets.

Steps (402), (404), (406) and (408) may respectively indicate logical ‘AND’ combinations of inputs, ABD, ABC, ACD and BCD. At step (410), a logical ‘OR’ combination of outputs generated from the steps (402), (404), (406) and (408) may be taken to generate the stress indicator, ‘Y’. By way of example, each of the inputs ‘A’, ‘B’, ‘C’ and ‘D’ may be either a logical ‘0’ or a logical ‘1’ depending on whether the inputs are within the predetermined threshold levels or not.
[0070] As used herein, and unless the context dictates otherwise, the term "coupled to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used euphemistically to mean “communicatively coupled with” over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0071] The terms, descriptions and figures used herein are set forth by way of illustration only. Many variations are possible within the spirit and scope of the subject matter, which is intended to be defined by the following claims and their equivalents in which all terms are meant in their broadest reasonable sense unless otherwise indicated.
