BACKGROUND OF THE INVENTION

[0002] The air exhaled by an individual carries valuable biological information that reflects metabolic processes and overall physiological balance. Careful evaluation of respiratory patterns and chemical markers present in breath provides meaningful insights into wellness status, disease progression, and recovery trends. The approach supports early identification of abnormalities and enables proactive health management without invasive procedures. Moreover, the approach is especially significant in routine medical check-ups, athletic performance tracking, chronic condition management, and remote care settings, where timely understanding of internal health changes enhances preventive care and informed clinical decisions.

[0003] The traditional approaches rely on laboratory-based testing, periodic clinical evaluations, and invasive sample collection to assess internal health conditions. However, the methods require scheduled visits, trained personnel, and extended processing time, which limits immediate feedback. Results are typically obtained after delays, reducing the ability to respond promptly to emerging concerns. Variations in interpretation and environmental factors also affects accuracy and consistency. Additionally, repeated procedures cause discomfort and inconvenience, restricting frequent assessment and making continuous, real-time health tracking challenging in everyday or remote settings.

[0004] BR112018070768A8 discloses a portable breath analysis device for analyzing a subject's breathing to identify levels of gases such as oxygen and carbon dioxide. The device is used, for example, in monitoring the health of subjects. Methods of analyzing a subject's respiration using the device are also provided herein.

The device finds use in, for example, monitoring the health of subjects. Also provided herein are methods of analysing breath of a subject using the device.

[0006] Conventionally, many devices disclosed in the prior art provide a means for evaluating respiratory biomarkers that relies on laboratory analysis, periodic clinical testing, and delayed result interpretation. However, the devices limit immediate feedback and continuous tracking. Moreover, real-time health insight is minimal, making comprehensive and timely assessment of physiological changes challenging and inconvenient for individuals.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to be capable of continuous evaluation of an individual’s health through breath analysis, assessing metabolic and respiratory indicators instantly, and providing personalized wellness insights. Additionally, the device also needs to enable early detection of anomalies, support proactive health management, and promote sustained well-being, comfort, and performance in both daily routines and clinical settings.

DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention relates to a breath analysis and health monitoring device developed for detecting potential health disorders, assessing metabolic and respiratory conditions, and enabling continuous real-time health evaluation with personalized wellness insights.

[0014] Referring to Figure 1, an isometric view of a breath analysis and health monitoring device is illustrated, comprising of a headgear 101 structure, a plurality of gripping pads 102 disposed along an inner edge of the headgear 101, a support rod 103 coupled to a rear portion of the headgear 101, a C shaped clamp 104 attached to a lower end of the support rod 103 via a motorized pivot joint 105, the clamp 104 including a drawer arrangement 106, an input means installed on the headgear 101 structure and comprises a touchscreen display panel 107 mounted on an articulated arm 108 connected with the headgear 101 and at least one microphone 109, an articulated linkage 110 with a clipper 111 at a distal end configured to hold a disposable mouthpiece 112, at least one artificial intelligence based camera 113 integrated onto the headgear 101 via an L-shaped link 114, a UV C LED array 115 embedded in the headgear 101, a haptic actuator 116 integrated in the headgear 101.

[0015] The device disclosed herein comprises of a headgear 101 structure configured to be securely worn on a user’s head. The headgear 101 includes a plurality of gripping pads 102 disposed along an inner edge to provide frictional engagement and stability during use. The headgear 101 further comprises a support rod 103 coupled to a rear portion thereof through a motorized ball-and-socket joint enabling controlled multi-directional adjustment relative to the user’s head position. A C-shaped clamp 104 is attached to a lower end of the support rod 103 via a motorized pivot joint 105, the clamp 104 incorporating a drawer arrangement 106 configured to automatically adapt to varying neck sizes, thereby providing adjustable neck support and maintaining alignment and positional stability of the headgear 101 during operation.

[0016] The headgear 101 structure operates by being positioned over the user’s head such that its internal contour aligns with the cranial profile. Upon placement, the structure distributes load evenly across contact regions while maintaining positional stability through balanced weight distribution. During use, the headgear 101 maintains a fixed orientation relative to the user’s head while allowing controlled adjustments via connected mechanical elements. The headgear 101 accommodates head movement without displacement by maintaining consistent contact pressure. The plurality of gripping pads 102 mentioned herein function by establishing frictional engagement between the headgear 101 and the user’s head surface.

[0017] Upon contact, the pads 102 compress slightly to conform to surface contours, thereby increasing contact area and resistance to slippage. During head movement, the pads 102 maintain consistent pressure distribution, preventing displacement of the headgear 101. The material composition of the pads 102 allows minor deformation to absorb motion-induced forces while restoring shape to retain grip efficiency. The pads 102 operate collectively to stabilize the headgear 101 under dynamic conditions by counteracting lateral, vertical, and rotational forces, ensuring secure positioning without causing discomfort or localized pressure concentration.

[0018] The support rod 103 operates as a structural linkage extending from the rear portion of the headgear 101 to a lower support assembly. During operation, the rod 103 transmits positional adjustments generated by connected joints while maintaining structural rigidity to support applied loads. The rod 103 maintains alignment between the headgear 101 and the neck support by providing a stable extension path. The rod 103 accommodates directional changes imparted by the motorized joint without bending or deformation. The rod 103 further functions as a load-bearing element that distributes mechanical forces evenly along its length, ensuring controlled movement, positional stability, and consistent support during adjustment and operational use.

[0019] The motorized ball-and-socket joint operates by enabling controlled rotational movement in multiple axes through a spherical coupler. Upon activation, the motor applies torque to reposition the ball element within the socket, allowing angular adjustments of the attached support rod 103 relative to the headgear 101. The joint maintains stable positioning once the desired orientation is achieved by resisting unintended movement. During operation, the joint facilitates smooth and precise directional changes while maintaining load support.

[0020] The motorized actuation of the joint allows automated or controlled repositioning to accommodate user head movements, thereby ensuring continuous alignment and adaptability without compromising stability. The C-shaped clamp 104 operates by partially encircling the user’s neck region to provide positional support and alignment stabilization. Upon engagement, the clamp 104 maintains a defined spacing that supports the neck without exerting excessive pressure. During operation, it holds the lower portion of the support assembly in a stable position relative to the user’s body.

[0021] The curved configuration of the clamp 104 allows the clamp 104 to maintain consistent contact along the neck contour while accommodating minor movements. The clamp 104 functions to counteract displacement forces acting on the headgear 101 by anchoring the support structure, thereby maintaining proper alignment and preventing unintended positional shifts. The motorized pivot joint 105 operates by enabling controlled angular movement between the support rod 103 and the attached clamp 104. When activated, the motor applies rotational force about a defined pivot axis, allowing the clamp 104 to reposition relative to the rod 103.

[0022] This movement of the pivot joint 105 permits adjustment of the clamp 104 orientation to maintain alignment with the user’s neck position. The pivot joint 105 maintains a stable fixed position once adjustment is completed by resisting reverse movement. During operation, it allows smooth, precise angular transitions while supporting applied loads, thereby ensuring stable attachment and maintaining the desired positional relationship between connected components. The drawer arrangement 106 mentioned above operates by enabling adjustable extension and retraction within the clamp 104 structure to accommodate varying neck sizes.

[0023] Upon engagement, the arrangement 106 slides along predefined tracks to increase or decrease the internal spacing of the clamp 104. During operation, the arrangement 106 maintains the adjusted position by resisting unintended movement once the desired size adaptation is achieved. The sliding operation of the arrangement 106 allows gradual dimensional adjustment while ensuring uniform contact distribution. The arrangement 106 functions to maintain proper alignment of the clamp 104 relative to the neck by adapting to size variations, thereby providing consistent support and preventing displacement during movement or prolonged use.

[0024] An input means is operatively coupled to an embedded microcontroller and is accessible to the user for enabling structured interaction with the device during operation. The input means is configured to receive user-provided data including demographic parameters such as age and gender, and subjective health status information, and to communicate corresponding signals to the microcontroller for processing. The input means further enables presentation of real-time procedural guidance and diagnostic outputs to the user. The input means comprises a touchscreen display panel 107 mounted on an articulated arm 108 connected to the headgear 101 and at least one microphone 109.

[0025] The touchscreen facilitates manual data entry, command execution, and mode selection, and the microphone 109 enables voice-based control for hands-free operation. The input means operates by continuously interfacing with the embedded microcontroller through a bidirectional signal pathway. Upon user interaction, entered demographic and health information is converted into digital input signals and transmitted to the microcontroller for immediate processing. The microcontroller validates, stores, and correlates the received data and generates corresponding control instructions. Simultaneously, the input means retrieves processed outputs from the microcontroller and presents them to the user as real-time guidance or diagnostic results.

[0026] The input means also monitors command inputs such as activation, deactivation, and mode selection, ensuring synchronized communication between user actions and device functions during operational cycles. The touchscreen display panel 107 herein functions by detecting user contact through capacitive sensing elements embedded within the display surface. Upon detection of touch input, corresponding positional coordinates are converted into electrical signals and transmitted to the microcontroller for interpretation. The microcontroller processes these signals to identify specific commands such as data entry, operational control, or mode selection.

[0027] The display panel 107 simultaneously receives processed output signals from the microcontroller to render visual information, including prompts, guidance instructions, and diagnostic results. The touchscreen display maintains continuous interactive communication with the control circuitry, thereby enabling real-time bidirectional exchange of operational data between the user and the device. The articulated arm 108 operates through interconnected pivot joints 105 configured to provide controlled angular movement of the mounted touchscreen display panel 107 relative to the headgear 101.

[0028] During operation, the arm 108 permits manual adjustment by the user, wherein applied mechanical force causes rotational displacement at the joints 105 while maintaining positional stability through frictional or locking elements. By enabling repositioning along multiple axes, the articulated arm 108 maintains optimal viewing and accessibility alignment for the user, thereby ensuring consistent operability of the display panel 107 during dynamic usage conditions. The microphone 109 operates by converting acoustic voice signals into corresponding electrical signals using an internal transducer element.

[0029] When the user provides a voice command, sound waves cause vibration of the transducer diaphragm, generating analog electrical signals proportional to the detected sound patterns. These signals are transmitted to the microcontroller, where they are digitized and processed through voice recognition protocols to identify corresponding operational commands. The microcontroller then executes appropriate control actions based on recognized inputs. The microphone 109 continuously monitors ambient acoustic input while filtering background noise, thereby enabling reliable hands-free interaction and real-time command execution during device operation.

[0030] An exhale unit is mounted on the headgear 101 to capture, direct, and evaluate exhaled air from the user in a controlled manner. The exhale unit includes an articulated linkage 110 terminating in a clipper 111 adapted to securely retain a disposable mouthpiece 112 in alignment with the user’s mouth. At least one fan is positioned within an internal flow path to actively draw exhaled breath through the exhale unit. A multi-gas sensor array is arranged along the flow path and comprises a plurality of gas sensors tuned to detect different volatile organic compounds and gas species, including acetone, ammonia, nitrogen oxides, sulfur-containing compounds, and alcohols.

[0031] The microcontroller processes detected gas concentrations, correlates predefined biomarker patterns with potential physiological conditions, and outputs corresponding indications to the input means for user awareness and monitoring. During operation, the exhale unit receives breath expelled through the mouthpiece 112 and channels it into an enclosed flow path. The fan generates a controlled negative pressure that continuously pulls exhaled air through the internal passage at a regulated rate. As the airflow moves along the path, gas constituents are exposed sequentially to sensing elements positioned within the exhale unit.

[0032] The microcontroller receives real-time sensor signals, performs signal conditioning, compares detected gas patterns against stored threshold profiles, and determines whether predefined biomarker conditions are satisfied. Upon confirmation, the microcontroller transmits processed results to the input means to display status indications and corresponding alerts. The articulated linkage 110 mentioned herein operates by allowing controlled positional adjustment of the mouthpiece 112 relative to the user’s face through pivoting or jointed segments. When deployed, the linkage 110 is maneuvered toward the user’s mouth, and the clipper 111 secures the disposable mouthpiece 112 in a fixed orientation.

[0033] The linkage 110 maintains spatial alignment during exhalation by resisting unintended displacement while permitting intentional repositioning through manual force. The fan operates by rotating its blades upon activation from the microcontroller, thereby generating a pressure differential within the flow path. This pressure gradient causes exhaled air to be drawn from the mouthpiece 112 inlet toward the downstream sensing region at a controlled velocity. The microcontroller regulates fan speed to maintain consistent airflow regardless of variations in exhalation force. Continuous airflow ensures uniform exposure of breath constituents to the sensing elements.

[0034] The multi-gas sensor array operates by exposing multiple sensing elements to the passing airflow within the internal flow path. Each sensing element produces an electrical response proportional to the concentration of specific gas constituents present in the exhaled breath. These electrical outputs are transmitted simultaneously to the microcontroller, which performs analog-to-digital conversion and signal normalization. The microcontroller evaluates combined sensor responses against predefined correlation matrices to identify characteristic biomarker patterns.

[0035] When specific threshold combinations are satisfied, the array output is interpreted as indicative of predefined physiological conditions, and corresponding data signals are generated for display or alerting purposes. Each gas sensor operates by selectively interacting with targeted volatile compounds present in the exhaled airflow passing through the sensing chamber. Upon exposure, the sensing material undergoes a measurable change in an electrical parameter, including resistance, voltage, or current output. This change is continuously monitored and transmitted as a sensor signal to the microcontroller.

[0036] The microcontroller samples outputs from all sensors concurrently, performs comparative analysis, and isolates distinct response signatures corresponding to individual gas species. The combined sensor outputs are then integrated to generate a composite gas profile representing the overall composition of the exhaled breath stream. At least one airflow sensor operatively disposed within the exhale unit to continuously monitor exhalation flow characteristics during a user’s breathing cycle so as to ensure consistent and reliable sampling conditions.

[0037] The airflow sensor is positioned to detect parameters including flow rate, flow direction, and temporal consistency of exhaled air passing through the exhale pathway. The sensor is communicatively coupled with the microcontroller to enable real-time verification of whether exhalation meets predetermined sampling thresholds, thereby facilitating accurate measurement, preventing invalid sample acquisition, and ensuring that collected respiratory data corresponds exclusively to controlled exhalation events. During operation, the airflow sensor detects movement of exhaled air as the user breathes into the exhale unit.

[0038] The airflow sensor generates electrical signals proportional to airflow velocity and direction as air passes through its sensing element. These signals are continuously transmitted to the microcontroller, where they are processed to determine whether the detected airflow satisfies predefined flow rate and duration criteria. If airflow remains stable within the required thresholds, the device permits sampling to proceed. Conversely, irregular, insufficient, or reverse airflow conditions cause the microcontroller to suspend sampling until proper exhalation flow is re-established and consistently maintained.

[0039] At least one temperature sensor and at least one humidity sensor are operatively associated with the exhale unit or headgear 101 and are configured to continuously monitor localized environmental parameters proximate to the user’s exhaled breath pathway. The temperature sensor is arranged to detect thermal variations corresponding to exhaled airflow conditions, while the humidity sensor is positioned to measure moisture concentration levels within the immediate breathing zone. Both sensors are electronically coupled to the microcontroller to enable real-time acquisition of environmental data relevant to breath characterization, compensation for ambient fluctuations, and enhancement of analytical accuracy.

[0040] The temperature sensor herein operates by continuously sensing thermal energy present in the immediate vicinity of the exhalation pathway and converting detected heat variations into corresponding electrical signals. Upon exposure to exhaled airflow, the sensing element undergoes a measurable change in an electrical parameter such as resistance, voltage, or current proportional to the detected temperature. This electrical variation is transmitted to an associated signal conditioning circuit where it is amplified, digitized, and forwarded to the microcontroller. The microcontroller correlates the received signal with calibrated reference values to determine real-time localized temperature conditions and ensures continuous monitoring during active breathing cycles.

[0041] The humidity sensor functions by detecting moisture concentration present in the surrounding air adjacent to the exhale unit and translating the sensed humidity level into a proportional electrical output. The sensing element absorbs or interacts with water vapor in the airflow, causing a measurable change in electrical characteristics such as capacitance, resistance, or frequency response. This change is immediately conveyed to an interfaced signal processing circuit where the signal is conditioned and converted into digital form. The processed data is then supplied to the microcontroller that continuously evaluates real-time humidity levels within the breathing zone during exhalation events.

[0042] A set of physiological sensors integrated within the headgear 101 and operatively coupled to the microcontroller for continuous monitoring of user physiological states. The physiological sensor set includes at least one electrocardiogram (ECG) sensor configured to detect cardiac electrical activity and derive heart rate and heart rate variability parameters, and at least one galvanic skin response (GSR) sensor configured to measure variations in skin conductance associated with autonomic nervous system activity and emotional arousal. The microcontroller processes real-time sensor inputs to identify elevated stress conditions and, upon detection thereof, actuates at least one haptic actuator 116 to generate vibration or visual guidance cues to facilitate relaxation or breathing exercises.

[0043] The set of physiological sensors operates by continuously acquiring bioelectrical and electro dermal signals from contact points positioned within the headgear 101. Each sensor converts physiological variations into corresponding electrical signals, which are transmitted to the microcontroller through conductive pathways. The microcontroller performs signal conditioning, filtering, and real-time data analysis to identify patterns indicative of autonomic nervous system activity. Sensor outputs are correlated to determine composite physiological states, including stress or relaxation levels. Upon detection of threshold deviations, the processed data triggers predefined device responses, including activation of feedback operations, thereby enabling closed-loop monitoring and responsive user guidance during device operation.

[0044] The ECG sensor herein functions by detecting minute electrical potentials generated by cardiac depolarization and repolarization cycles through conductive electrodes positioned in contact with the user’s skin. These electrodes capture voltage fluctuations and transmit analog signals to an amplification and filtering circuit to remove noise and motion artifacts. The conditioned signals are digitized and relayed to the microcontroller, which identifies waveform components such as QRS complexes and R-R intervals. Using these measurements, the microcontroller calculates heart rate and heart rate variability in real time, enabling continuous assessment of cardiovascular activity and providing actionable physiological indicators for device response.

[0045] The GSR sensor mentioned above operates by applying a low, imperceptible electrical current across two skin-contact electrodes and measuring variations in electrical conductance resulting from sweat gland activity. Changes in moisture levels on the skin surface alter resistance values, which are continuously detected by the sensor circuitry. These variations are converted into electrical signals and transmitted to the microcontroller for processing. The microcontroller analyzes conductance fluctuations over time to identify patterns associated with sympathetic nervous system activation. When conductance levels exceed predetermined thresholds, the processed data is used to determine emotional arousal or stress conditions for subsequent device action.

[0046] The haptic actuator 116 mentioned above operates by receiving control signals from the microcontroller upon detection of elevated stress indicators derived from physiological sensor data. The actuator 116 converts electrical input into mechanical vibration through an internal motor. The microcontroller modulates vibration intensity, frequency, and duration according to predefined feedback patterns corresponding to guided relaxation or breathing exercises. These tactile signals are transmitted directly to the user through the headgear 101 structure, providing non-intrusive sensory feedback.

[0047] At least one infrared thermopile sensor securely mounted on the headgear 101 to non-invasively detect and measure the skin surface temperature of the user, and at least one laser Doppler flow sensor positioned to monitor blood flow velocity and/or volumetric perfusion within a targeted skin region. The infrared thermopile sensor and the laser Doppler flow sensor are operatively connected to the microcontroller and function in a time-synchronized manner to ensure temporally aligned physiological measurements. The microcontroller is further configured to process and correlate the synchronized thermal and perfusion data with breath volatile organic compound (VOC) patterns so as to identify febrile conditions, abnormalities in peripheral circulation, and related physiological states, thereby improving diagnostic reliability and reducing false interpretations.

[0048] The infrared thermopile sensor operates by passively receiving infrared radiation emitted from the skin surface and converting the detected thermal energy into a proportional electrical voltage through a series of thermocouple junctions arranged in a thermopile configuration. The sensor continuously samples radiation intensity within its field of view while compensating for ambient temperature variations using an integrated reference element. The generated analog voltage corresponding to skin temperature is transmitted to the microcontroller through a signal conditioning circuit, where it is digitized and timestamped. The microcontroller synchronizes this temperature data with concurrent physiological inputs to enable temporally accurate correlation and continuous thermal monitoring.

[0049] The laser Doppler flow sensor mentioned above operates by emitting a coherent low-power laser beam onto the targeted skin region and detecting frequency shifts in the reflected light caused by the movement of red blood cells within underlying microvasculature. The sensor’s photodetector captures the backscattered light, and an internal processing circuit converts Doppler frequency variations into electrical signals indicative of blood flow velocity and perfusion volume. These signals are continuously amplified, filtered, and transmitted to the microcontroller, where they are digitized and time-aligned with other physiological inputs. The synchronized flow data is then used for real-time assessment of peripheral circulation dynamics.

[0050] At least one artificial intelligence-based camera 113 securely integrated onto the headgear 101 through an L-shaped link 114 and structurally oriented toward a predefined forward-facing direction corresponding to a user’s facial region. The camera 113 is operatively configured to continuously capture visual data relating to facial expressions, micro-movements, and positional alignment. The camera 113 processes the captured data through embedded artificial intelligence protocols for detection and monitoring purposes. Further, the camera 113 is functionally enabled to operate only upon confirmation that the headgear 101 is properly positioned on the user, thereby ensuring operational accuracy, minimizing erroneous data capture, and maintaining controlled activation conditions.

[0051] The artificial intelligence-based camera 113 functions by continuously capturing real-time visual frames of the user’s facial region once activation conditions are satisfied. The captured image data is transmitted to the microcontroller where machine-learning protocols perform facial recognition, expression mapping, and motion tracking through pattern detection and feature extraction techniques. The microcontroller verifies correct headgear 101 positioning using alignment parameters before enabling full operation. Upon validation, the camera 113 dynamically monitors changes in facial orientation, muscle movement, and behavioral indicators, converts these into digital signals, and transmits processed outputs to associated control modules for further responsive action.

[0052] The L-shaped link 114 mentioned above operates as a rigid structural connector that positions and stabilizes the camera 113 relative to the headgear 101. One arm of the link 114 remains securely affixed to the headgear 101 frame, while the perpendicular arm extends outward to hold the camera 113 at a predetermined distance and angle aligned with the user’s face. The geometry of the link 114 maintains consistent orientation despite head movements, reduces vibration transfer, and ensures positional accuracy during operation. The link 114 further distributes mechanical loads evenly across attachment points, thereby preserving structural integrity, preventing misalignment, and enabling reliable and stable camera 113 positioning during continuous monitoring conditions.

[0053] A UV-C LED array 115 structurally embedded within at least one of the headgear 101 portion and the exhale unit to direct germicidal ultraviolet radiation toward internal surfaces and a mouthpiece 112 interface to achieve disinfection between successive uses. The UV-C LED array 115 is operatively coupled to the microcontroller configured to regulate emission parameters, including exposure duration and intensity, so as to ensure effective microbial inactivation while preventing excessive irradiation. At least one exposure-time or intensity sensing element is communicatively linked to the microcontroller to monitor delivered UV dosage.

[0054] The microcontroller is further configured to automatically initiate a disinfection cycle upon detection of removal of a disposable mouthpiece 112 and to disable UV emission whenever the headgear 101 is sensed as being worn, thereby ensuring user safety while maintaining adequate sterilization of internal surfaces. The UV-C LED array 115 herein operates upon receipt of an activation command from the microcontroller following confirmation that the disposable mouthpiece 112 has been removed and the headgear 101 is not being worn. Electrical power is supplied to the LEDs in controlled pulses to emit ultraviolet radiation within a germicidal wavelength range.

[0055] The microcontroller regulates current flow, duty cycle, and emission duration to achieve a predetermined irradiation dose across internal surfaces. Optical distribution is maintained through fixed angular placement of LEDs to ensure uniform exposure. Upon completion of the programmed cycle, or upon detection of a wear condition, the microcontroller immediately terminates power supply to cease UV emission. The exposure time or intensity sensor continuously measures at least one parameter indicative of delivered ultraviolet dosage during operation of the UV-C LED array 115.

[0056] The sensor generates electrical signals corresponding to detected radiation intensity levels or cumulative exposure duration and transmits such signals to the microcontroller in real time. The microcontroller processes the incoming data against preset disinfection thresholds and dynamically adjusts LED drive current or exposure timing to maintain the required dosage. If measured values exceed safe operational limits or fall below required sterilization levels, the microcontroller correspondingly reduces, increases, or terminates LED emission to ensure both effective disinfection and operational safety.

[0057] A microphone 109 array mounted on, embedded within, or positioned in proximity to the headgear 101 to capture audible inputs including the user’s speech signals and respiratory acoustic patterns during inhalation and exhalation. The array further includes at least one airflow sensor operatively associated with the headgear 101 to monitor exhalation flow characteristics, including rate, direction, and temporal variations. The combined configuration enables synchronized acquisition of acoustic and airflow-related data so as to facilitate accurate detection, recording, and analysis of vocal commands and breathing patterns under operational conditions without requiring manual user intervention.

[0058] The microphone 109 array operates by simultaneously receiving acoustic waves through multiple spatially distributed microphones 109 positioned on or near the headgear 101. Each microphone 109 converts detected sound pressure variations into corresponding electrical signals, which are transmitted to the microcontroller. The microcontroller performs signal conditioning, amplification, and filtering to remove background noise and isolate relevant speech and respiratory sound components. The processed output is then digitized and forwarded for further analysis, enabling accurate identification of speech inputs and breathing-related acoustic patterns in real time.

[0059] The exhale unit further includes a defined flow channel structured to guide exhaled breath in a controlled manner. The microcontroller is operatively configured to verify the validity of each collected breath sample through coordinated analysis of inputs received from the airflow sensor, the temperature sensor, and the humidity sensor. The microcontroller evaluates whether the detected breath satisfies predetermined criteria including minimum flow rate, required exhalation duration, and acceptable environmental parameter ranges. Upon determining that any of the prescribed sampling conditions are not fulfilled, the microcontroller automatically generates a prompt instructing the user to repeat the exhalation process to obtain a compliant and reliable breath sample.

[0060] A local data storage module is operatively coupled to the microcontroller to securely retain a personalized health profile corresponding to each individual user. The stored profile includes, without limitation, historical breath analysis records, physiological parameter measurements, and baseline values derived from sensor outputs over a defined monitoring period. The microcontroller is further configured to continuously reference the stored baseline data and dynamically modify alert thresholds, analytical parameters, and diagnostic evaluations in response to detected deviations from the established individual norms, thereby enabling user-specific assessment, improved accuracy of condition monitoring, and adaptive interpretation of real-time physiological and respiratory sensor data.

[0061] A wireless communication interface configured as an Internet-of-Things (IoT) module is operatively integrated within the headgear 101 to enable secure, remote data exchange with an external cloud-based predictive analytics module. The interface is structured to selectively collect, preprocess, and transmit anonymized sensor-derived features and summarized analytical outputs while excluding personally identifiable information, thereby ensuring compliance with data privacy requirements. The interface further facilitates bidirectional communication, wherein processed datasets are communicated to the remote analytics module that executes predefined disease progression protocols and risk evaluation models, and subsequently returns computed risk scores, prognostic indicators, and actionable recommendations, which are then rendered for user awareness through the designated input means.

[0062] At least one gyro sensor is integrally embedded within the headgear 101 and the support rod 103 to continuously monitor angular displacement, rotational orientation, and positional changes of the user’s head during operation. The gyro sensor is electronically coupled to the microcontroller to process real-time motion data and generate corresponding control signals. Upon detection of head movement beyond a predefined threshold, the microcontroller actuates the motorized ball-and-socket joint together with the motorized pivot joint 105 so as to automatically reposition and realign the headgear 101 and the exhale unit. This automated adjustment ensures consistent sensor alignment, maintains optimal placement relative to the user’s anatomical reference points, and preserves operational accuracy during dynamic user motion.

[0063] The gyro sensor operates by continuously sensing angular velocity and rotational orientation of the headgear 101 relative to a fixed reference axis. During user movement, the sensor generates electrical signals proportional to detected rotational changes. These signals are transmitted in real time to the microcontroller, which compares the measured orientation with predefined alignment parameters. When deviation beyond permissible limits is detected, the microcontroller immediately issues corrective control commands to the motorized joints. The joints then reposition the headgear 101 until the gyro sensor output returns within acceptable alignment thresholds, thereby ensuring continuous stabilization and maintaining precise positioning throughout dynamic motion conditions.

[0064] The present invention works best in following manner, where the device is positioned on the user through the headgear 101 structure such that the plurality of gripping pads 102 stabilize contact along the inner edge while the support rod 103, actuated through the motorized ball and socket joint, automatically aligns orientation relative to head posture. The motorized pivot joint 105 adjusts the C shaped clamp 104 and the drawer arrangement 106 conforms to neck dimension to maintain consistent positional stability during operation. The input means mounted on the articulated arm 108 enables the user to enter demographic and health parameters through the touchscreen display panel 107, while the microphone 109 enables hands free command input, and the embedded microcontroller processes received data to initialize personalized diagnostic protocols and operational modes. During breath analysis, the articulated linkage 110 positions the clipper 111 to secure the disposable mouthpiece 112, and the fan draws exhaled breath through the defined internal flow channel. The airflow sensor continuously verifies exhalation consistency, while the temperature sensor and the humidity sensor validate environmental conditions to ensure sampling reliability.

[0065] In continuation, the multi gas sensor array detects volatile organic compounds including acetone, ammonia, nitrogen oxides, sulfur compounds, and alcohols, and the microcontroller correlates detected patterns with stored diagnostic models to generate real time health indications for display. Simultaneously, the physiological sensors monitor cardiac and autonomic parameters, wherein the ECG sensor measures electrical cardiac signals and the galvanic skin response sensor detects skin conductance variations, and the microcontroller evaluates combined outputs to determine stress levels and triggers the haptic actuator 116 and visual guidance prompts for relaxation assistance. The infrared thermopile sensor measures skin temperature while the laser Doppler flow sensor evaluates peripheral blood flow, and synchronized outputs are integrated with breath biomarkers by the microcontroller to improve condition assessment. The artificial intelligence based camera 113 continuously verifies facial alignment and detects expression changes to confirm proper positioning and user engagement. The microphone 109 array captures respiratory acoustics for supplementary analysis of breathing patterns. The gyro sensor monitors head motion and enables the microcontroller to drive automatic realignment of the motorized joints to maintain optimal sensor positioning. Following completion of usage, the microcontroller initiates the UV C LED array 115 disinfection cycle upon detection of mouthpiece 112 removal while inhibiting emission when the headgear 101 is worn. The local storage module maintains personalized health profiles and adaptive baselines, and the wireless communication interface transmits anonymized data to the remote predictive analytics module, thereby enabling continuous risk evaluation and updated diagnostic feedback through the input means.

It can be used in hospitals, diagnostic centers, clinics, and home healthcare environments for non-invasive health screening and routine monitoring. The invention is also applicable in occupational health settings for periodic health assessment of workers, as well as in telemedicine services to support remote evaluation and follow-up care. Further, the device is utilized in research institutions for studying physiological patterns and disease indicators. The ability of the device to provide quick, repeatable, and user-guided assessments makes it suitable for large-scale health screening programs and continuous personal health management systems.
