Description:FIELD OF THE INVENTION

[0001] The present invention relates to a wearable device for epileptic seizure detection and safety management that continuously monitors vital physiological and environmental parameters to provide real-time protection and support for individuals prone to sudden epileptic seizure events for enhancing safety and minimizing injury through automated intervention.

BACKGROUND OF THE INVENTION

[0002] Individuals prone to sudden neurological events such as epileptic seizure face significant risks from uncontrolled muscle spasms, respiratory irregularities, and adverse environmental conditions, which lead to injury, discomfort and prolonged recovery times. Current protective measures are passive and lack real-time responsiveness, limiting their effectiveness in preventing harm during critical moments. They do not continuously monitor physiological and environmental parameters to detect early signs of distress, nor do they provide immediate therapeutic interventions. Moreover, they don’t offer active temperature regulation to maintain comfort and reduce seizure triggers, support respiration during abnormal breathing patterns, or deliver targeted muscle relief to alleviate stiffness and promote circulation. Such features are essential to enhance user safety, reduce complications and improve the quality of life for individuals vulnerable to seizure-related health issues.

[0003] Traditionally, individuals managing seizure-related conditions rely on separate, manual tools such as wearable heart rate monitors, standalone EEG headbands, portable temperature regulators and external oxygen support arrangement. These devices operate independently, requiring constant user attention, manual activation, and frequent calibration, which is impractical during or just before a seizure episode. Manual breathing aids and heating pads offer limited, non-responsive relief and cannot adapt in real time to the user's changing physiological state. Similarly, conventional protective gear like helmets or cushions helps to reduce injury. This fragmented approach not only delays intervention but also burdens the user or caregiver with the responsibility of continuous monitoring and operation. As a result, critical time is lost during emergencies, reducing the effectiveness of each tool and increasing the risk of injury, discomfort or incomplete recovery, highlighting the urgent need for a unified solution.

[0004] WO2025133790A1 discloses a wearable device for real-time monitoring and predicting epileptic seizures. The wearable device comprises a plurality of dry Electroencephalogram (EEG) electrodes to capture EEG signals of a subject. The wearable device further comprises a neuromorphic computing unit configured to analyse the captured EEG signals in real-time using neural network models trained on epileptic seizure data to detect abnormalities in brain activity of the subject. These abnormalities indicate preictal phase of epileptic seizure. The wearable device further comprises an alert mechanism to notify the subject upon detection of abnormalities in brain activity.

[0005] CN221512340U discloses a protective devices, and discloses an epileptic seizure protective device which comprises a shell, a first protective pad is fixedly arranged in the shell, a plurality of air cushions are fixedly arranged in the first protective pad, a foam fixing ring is fixedly arranged at the inner top of the first protective pad, and a plurality of air cushions are fixedly arranged in the foam fixing ring. A foam fixing ring is fixedly arranged on the inner side of the shell, a plurality of foam strips are fixedly arranged on the inner side of the foam fixing ring, first fixing columns are fixedly arranged on the two sides of the shell, threaded grooves are formed in the two first fixing columns, and bolts are engaged with the two threaded grooves. According to the utility model, the first protection pad is arranged on the inner side of the shell to form a layer of protection, and then a plurality of air cushions are arranged to protect important positions of a patient, so that the injury to the patient is reduced, meanwhile, the foam strips can protect the head top of the patient, and the foam fixing ring is matched for use to form protection and fix the head of the patient at the same time; and the head of the patient can be placed at a correct position.

[0006] Conventionally, many devices have been developed to monitor epileptic seizure, assist in temperature control, provide respiratory aid or offer physical protection during epileptic seizure events, but these devices lack real-time integration, automated responsiveness and synchronized therapeutic intervention. These existing devices operate independently without analyzing combined physiological and environmental data, resulting in delayed responses, limited protection and insufficient recovery support especially during sudden, unpredictable events such as seizures where timely, coordinated action is critical.

[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 autonomously monitoring physiological and environmental changes, detecting early warning signs of epileptic seizure and autonomously triggering protective and therapeutic actions to enhance user safety, ensure timely intervention, support vital functions, reduce post-episode complications and eliminate the need for manual operation for improving overall quality of care and independence.

[0024] Referring to Figure 1 and 2, a front view of a wearable device for epileptic seizure detection and safety management and an isometric view of a face protection unit and breathing support module associated with the present device for epileptic seizure detection and safety management are illustrated, comprising a wearable body 101 attached with a cap 102, an input means 103 installed on the body 101, an artificial intelligence-based imaging unit 104 mounted on a collar portion of the body 101, an audio output module 105 installed on the body 101, an embedded gel layer 106 integrated within the body 101, a plurality of rotary units 107 installed in the body 101, an expandable cushioned plate 108 installed in the body 101, a lightweight fiberglass shield 201 installed in the cap 102 via a spare visor assembly 202 and a medical-grade silicone mask 203 installed on inner portion of the shield 201 via an extendable hollow member 204 connected with a filtered air container 205.

[0025] The device disclosed herein comprises of a wearable body 101 attached with a cap 102 configured to conform user’s torso, extending from the shoulders down to the waist, ensuring full upper-body coverage without restricting mobility. The cap 102 is attached to the upper section of the body, forming a continuous protective shell that encloses the head while maintaining ergonomic alignment with the neck and shoulders. Both components are constructed using multi-layered, impact-absorbing materials includes but not limited to viscoelastic foam, gel padding or polymers distributed across high-risk zones including the spine, ribs and skull. The body 101 is flexible and contoured to follow the natural curvature of the human body, allowing the wearable to remain close-fitting yet adaptable during movement. The overall form resembles a soft exoskeleton, lightweight and low-profile, optimized to minimize injury from falls or collisions associated with seizures, while ensuring user comfort and discretion for daily wear.

[0026] A user is required to activate the device manually by pressing a button installed on the wearable body 101 and linked with an inbuilt microcontroller associated with the device. The button is a type of switch that is internally connected with the device via multiple circuits that upon pressing by the user, the circuits get closed and starts conduction of electricity that tends to activate the device and vice versa.

[0027] An input means 103 is installed on the wearable body 101 to facilitate the user for entering, updating and managing personal medical data in real-time, which is then stored in a linked database for future retrieval and analysis. The input means 103 mentioned herein includes but not limited to a touch interactive display panel and a user interface installed in a computing unit wirelessly linked with the body 101.

[0028] In an embodiment of the present invention, the user accesses the touch interactive display panel that facilitates the user in providing vital information such as medical history, current medications, known seizure triggers or recent symptoms for future retrieval and analysis. The touch interactive display panel as mentioned herein is an LCD (Liquid Crystal Display) screen that presents output in a visible form. The screen is equipped with touch-sensitive technology, allowing the user to interact directly with the display using their fingers. A touch controller IC (Integrated Circuit) is responsible for processing the analog signals generated when the user inputs details for medical history, current medications, known seizure triggers or recent symptoms. A touch controller is connected to the microcontroller through various interfaces which include but are not limited to SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit).

[0029] In another embodiment of the present invention, the user access the user interface installed within the computing unit to provide vital information such as medical history, current medications, known seizure triggers or recent symptoms for future retrieval and analysis. The user interacts with the interface through a touch screen, keyboard or other input methods available on the computing unit. The computing unit mentioned herein includes, but is not limited to smartphone, tablet or laptop that comprises a processor that receives data from the microcontroller, stores, processes and retrieves the output in order to display on the computing unit.

[0030] A communication unit for establishing a wireless connection between the body 101 and the computing unit . The communication unit used herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication unit used herein is preferably a Wi-Fi module that is a hardware component that enables the microcontroller to connect wirelessly with the computing unit. The Wi-Fi module works by utilizing radio waves to transmit and receive data over short distances. The core functionality relies on the IEEE 802.11 standards, which define the protocols for wireless local area networking (WLAN). Once connected, the unit allows the microcontroller to send and receive data through data packets.

[0031] An artificial intelligence-based imaging unit 104 is mounted on a collar portion of the wearable body 101, to maintain an unobstructed, stable view of the user’s face and upper body to capture detailed facial expressions and subtle physical cues such as eye movement, jaw tension or head tremors. The collar’s curved geometry ensures the imaging unit 104 remains centered and aligned with the user’s face regardless of posture. Upon activation of the device, the microcontroller activates the imaging unit 104 that comprises of an image capturing module including a set of lenses that captures multiple high-resolution images to determine facial expressions of the user and physical cues for seizure indicators, then the captured images are stored within memory of the imaging unit 104 in form of an optical data.

[0032] The imaging unit 104 incorporates a processor that is fed with an artificial intelligence protocol which operates by following a set of predefined instructions to process optical data and perform tasks autonomously. Initially, captured images are collected and input into a database, which then employs protocol to analyze and interpret the optical data. The processor of the imaging unit 104 via the artificial intelligence protocol processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and transmits to the microcontroller to determine user's facial expressions and identify physical cues that indicate seizures.

[0033] A sensor suite is integrated into the wearable body 101 to enable continuous, real-time monitoring of both the user’s vital health parameters and surrounding environmental conditions. The sensor suite includes one or more EEG (Electroencephalogram) sensors is embedded within the inner surface of the wearable’s cap region, where they maintain direct contact with the scalp to detect and record the brain’s electrical activity across various frequency bands such as alpha, beta, theta and delta waves associated with different neurological states. The EEG sensors works when electrodes, commonly dry or semi-dry, are placed in contact with the scalp to detect electrical potentials generated by neuronal activity.

[0034] These analog signals are extremely low in amplitude (microvolt range), so they are first passed through a low-noise preamplifier to boost the signal without distortion. The amplified signals are then filtered by a band-pass filter to isolate relevant brainwave frequencies, removing noise and artifacts such as muscle movement or environmental interference. The cleaned signals are then digitized using an analog-to-digital converter (ADC) and then transmits to the microcontroller to process the signal and correlates the brainwave patterns with predefined neurological and cognitive activity levels stored in a database. This analysis helps detect abnormalities such as sudden spikes, rhythm disruptions or unusual frequency dominance, serving as contributing indicators for seizure prediction, mental fatigue, stress or other neurological irregularities.

[0035] The sensor suite also includes one or more PPG (Photoplethysmography) sensor is embedded within the inner surface of the wearable body 101, to monitor blood flow and heart rate in real time. The sensor works when an LED light source normally a green, red or infrared emitting light into the skin. As the light penetrates the tissue, interacts with blood vessels; changes in blood volume during cardiac cycles affect how much light is absorbed or reflected. A photodetector, positioned adjacent to or opposite the LED (in reflectance or transmission mode), captures the returning light.

[0036] The detected light intensity fluctuates with each heartbeat, producing a raw analog signal. This signal is then passed through a low-noise amplifier to boost and a band-pass filter to eliminate ambient light and motion artifacts. The filtered signal is digitized by an analog-to-digital converter (ADC) and sent to the microcontroller which correlates the values with cardiovascular health levels using predefined data stored in the database. This process helps detect anomalies such as irregular heart rate, reduced blood flow or stress-induced fluctuations, serving as contributing indicators for seizure prediction or general cardiovascular health assessment.

[0037] The sensor suite further includes one or more bio-impedance sensor is embedded within the inner surface of the wearable body 101, to monitor the user's hydration levels in real time. The sensor works by using a set of electrodes to measure the body’s electrical impedance, which reflects tissue hydration levels. Two current-injecting electrodes apply a low-amplitude, high-frequency alternating current to the skin. This current flows through body tissues, encountering resistance and reactance based on the water and electrolyte content. Two additional voltage-sensing electrodes placed nearby measure the resulting voltage drop across the tissue. This voltage is fed into a differential amplifier to isolate the bio-impedance signal, which is then passed through analog filters to remove noise and motion artifacts. Then the signal is digitized using an analog-to-digital converter (ADC) and transmits to the microcontroller which correlates the impedance values with hydration levels using predefined data stored in the database that helps detect dehydration levels, serving as contributing indicators for seizure prediction or general health assessment.

[0038] The sensor suite furthermore includes one or more EMG (Electromyography) sensors embedded within the inner surface of the wearable body 101, such as the shoulders, arms, or neck to detect real-time muscle activity and strain levels. The sensor works by detecting electrical activity produced by skeletal muscles during contraction. The system begins with surface electrodes placed on the skin over target muscle groups; these electrodes capture the small electrical potentials generated by muscle fiber depolarization. The raw analog signals, in the microvolt to millivolt range, are first sent to a differential amplifier, which amplifies the signal while canceling out common-mode noise. The amplified signal then passes through band-pass filters to remove low-frequency motion artifacts and high-frequency noise. Then signal is digitized using an analog-to-digital converter (ADC) and sent to the microcontroller which correlates the values with muscle activity and strain readings using predefined data stored in the database that helps detect abnormal muscle tension, involuntary contractions, or spasms, serving as contributing indicators for early seizure onset, muscular fatigue or neuromuscular disorders.

[0039] The sensor suite furthermore includes one or more EDA (Electrodermal Activity) sensors positioned within the inner surface of the wearable body 101 having high sweat gland density such as the palms or inner forearms, to monitor skin conductance changes related to stress and nervous system activity. The sensor works by measuring the skin’s electrical conductance, which varies with sweat gland activity linked to stress or emotional arousal. The system uses two surface electrodes placed on the skin, between which a small, constant voltage is applied by a constant current source or voltage source circuit. Changes in sweat secretion alter the skin’s resistance, causing fluctuations in the measured conductance. These small analog signals are detected by a high-impedance differential amplifier to ensure accurate measurement without drawing significant current. The amplified signal is then passed through low-pass filters to remove noise from movement and environmental interference. The filtered signal is converted to a digital format by an analog-to-digital converter (ADC) and sent to the microcontroller which correlates the conductance values with stress or emotional arousal levels using predefined reference data stored in the database. This analysis helps detect heightened stress states or anxiety, which serve as contributing indicators for seizure prediction or overall health assessment.

[0040] The sensor suite furthermore includes one or more force-sensitive resistors (FSRs) embedded within the inner surface of the wearable body 101 such as the neck and wrist regions, to monitor pressure levels that indicate muscle stiffness, strain, or positional stress. The force-sensitive resistors work by changing their resistance based on the amount of pressure or force applied. Each FSR consists of a conductive polymer layer placed over a set of interdigitated electrodes. When no force is applied, the resistance is very high; as force increases, the conductive particles in the polymer compress and create more contact points with the electrodes, reducing the resistance. The FSR is part of a voltage divider circuit, where a fixed resistor is paired with the FSR to convert resistance changes into a variable voltage signal. This analog signal is then sent to an amplifier to enhance sensitivity, followed by a low-pass filter to eliminate high-frequency noise caused by vibrations or minor movement. The filtered signal is digitized via an analog-to-digital converter (ADC) and then transmits to the microcontroller, which correlates the values with muscular pressure or strain readings using predefined data stored in the database that helps detect early signs of seizure-related muscle tightening, postural abnormalities or sustained pressure points, serving as contributing indicators for seizure prediction or general musculoskeletal health monitoring.

[0041] The sensor suite furthermore includes one or more pressure sensors embedded within the inner surface of the wearable body 101, particularly around the chest or abdominal region to detect subtle expansions and contractions associated with the user’s breathing patterns. The pressure sensor works through a layered structure consisting of a flexible substrate, a pressure-sensitive material and conductive electrodes. When the user breathes, the expansion and contraction of the chest or abdomen cause deformation of the structure. This deformation alters the capacitance between the electrodes. The change in electrical signal is then routed through conductive traces to an analog front-end circuit, to get amplified, filtered to remove noise and converted from analog to digital using an ADC (Analog-to-Digital Converter) and then transmits to the microcontroller which correlates the pressure sensor readings with concurrent inputs from other sensors such as heart rate from PPG, brainwave data from EEG and muscle activity from EMG using predefined reference threshold values stored in the database. This multi-parameter comparison helps identify abnormalities in breathing, such as apnea, hyperventilation, or irregular respiratory patterns, which act as early or accompanying signs of seizure activity or physiological distress.

[0042] The sensor suite furthermore includes one or more gyroscopic sensor embedded on surface of the wearable body 101, to monitor the angular velocity and orientation of the user’s body across multiple axes, determining dynamic movements such as rotation, tilt or sudden falls. The sensor works by using a microelectromechanical arrangement that measures angular velocity along one or more axes. Inside the sensor, a tiny vibrating structure commonly a suspended mass or proof mass moves in response to angular rotation due to the Coriolis effect. This movement causes a shift in capacitance or voltage between internal electrodes. The sensor’s internal circuitry detects these changes and converts them into analog signals proportional to the rate of rotation. These analog signals are passed through an amplifier and filtered to reduce noise. An onboard Analog-to-Digital Converter (ADC) then digitizes the signals and transmits to the microcontroller which correlates the data with predefined values stored in the database that helps to detect abnormal motion sequences like convulsions, repetitive jerks or sudden collapse, which are common physical manifestations preceding or accompanying seizures.

[0043] The sensor suite furthermore includes one or more temperature sensor coupled with humidity sensor embedded within the wearable body 101, to continuously measure the ambient environmental conditions surrounding the user, providing real-time data on heat levels and moisture in the air. The temperature sensor works by capturing the infrared radiation emitted by surrounding air particles and surfaces. The sensor consists of a thermopile with a built-in lens or filter, that collects and focuses IR radiation onto a sensing element. The thermopile absorbs this radiation, generating a voltage through the Seebeck effect, proportional to the ambient temperature. The analog voltage signal from the thermopile is amplified and digitized by an analog-to-digital converter (ADC) and then transmits to the microcontroller. Simultaneously, the humidity sensor measures moisture content in the surrounding air by measuring changes in relative humidity based on variations in electrical capacitance.

[0044] The sensor consists of two conductive electrodes, a hygroscopic dielectric layer (a polymer or metal oxide) and a signal processing circuit. The dielectric material is sensitive to moisture and absorbs water vapor from the air. As the ambient relative humidity increases, more water molecules are absorbed, increasing the dielectric constant of the material and consequently, the capacitance between the electrodes. This change in capacitance is directly related to the humidity level and then a signal conditioning circuit convert that into a measurable voltage and an analog-to-digital converter (ADC) digitizes this signal and transmits to the microcontroller, which processes the both data by correlating with predefined environmental thresholds and user-specific tolerance values stored in a database. This helps identify potentially stressful or triggering conditions such as excessive heat, dehydration risks or high humidity that increase the likelihood of seizures or impact overall health.

[0045] An audio output module 105 is installed on the wearable body 101 and operatively linked with the sensor suite, to provide immediate audible feedback in response to physiological changes in hydration level and vitals of the user. Upon detecting abnormal or threshold-exceeding parameters such as dehydration, irregular heart rate or respiratory distress, the microcontroller signals the audio module 105 to emit distinct, pre-programmed alert tones for alerting the user. The audio output module 105 used herein preferably a speaker that works by converting the electrical signal into the audio signal, consists of a cone known as a diaphragm attached to a coil-shaped wire placed between two magnets. When the electric signal is passed through the voice coil, generates a varying magnetic field that interacts with the magnet causing the diaphragm to move back and forth. This movement creates pressure variations in the surrounding air, generating sound waves in order to alert the user to take necessary corrective actions.

[0046] A temperature regulation module is integrated within the wearable body 101, to maintain optimal body temperature and enhance user comfort, particularly for individual sensitive to temperature fluctuations that trigger seizures. The temperature regulation module includes a Peltier module that is capable of providing both heating and cooling to an embedded gel layer 106 that lies close to the user’s skin. When the sensor suite detects real-time environmental parameters such as ambient temperature and humidity alongside physiological feedback like skin temperature and electrodermal activity that contribute to thermal stress levels, the microcontroller activates the Peltier module that works on the thermoelectric effect, using two different types of semiconductor materials arranged in pairs between two ceramic plates.

[0047] When a DC electric current is applied, electrons and holes move through the semiconductors, transferring heat from one side of the module to the other. This creates a temperature difference: one side becomes cold (absorbs heat) and the opposite side becomes hot (dissipates heat). A heat sink is attached to the hot side to manage excess heat, ensuring stable operation. This thermal energy is transferred to the adjacent gel layer 106, allowing the Peltier module to precisely regulate the surface temperature. In cooling mode, the Peltier draws heat away from the gel layer 106 and dissipates externally, while in heating mode, adds warmth to the gel, which then gently raises the temperature of the skin-contact area. This ensures rapid, localized thermal adjustment, evenly distributed via the gel for user comfort to reduce thermal discomfort and helps prevent temperature-related seizure triggers.

[0048] A face protection unit is integrated into the cap section of the wearable body 101, to prevent facial injuries during epileptic seizures. The face protection unit comprises of a lightweight, fiberglass shield 201 housed in a compact, retractable configuration within the upper region of the cap 102. This shield 201 is linked to a spare visor assembly 202 that includes a micro-servo motor and a ratchet for deployment. Upon detection of seizure precursors or abnormal movements such as sudden head jerks, muscle contractions or facial tension by the imaging unit 104 and sensor suite, the microcontroller activates micro-servo motor that rotates a connected shaft accordingly, which is directly linked to a gear that meshes with a semi-circular ratchet track integrated into the visor mount. The track features evenly spaced teeth along edges. The pawl, a small lever mounted on a pivot point, engages with these teeth to lock the visor in discrete angular positions.

[0049] A compression spring biases the pawl into constant contact with the ratchet teeth, ensuring automatically locks into the next available notch during motion. As the servo rotates, drives the angled face of each tooth pushes the pawl upward, allowing to ride over the crest and drop into the next notch due to spring force. This action moves the visor in incremental steps, with the ratchet teeth ensuring unidirectional locking at each set angle. The ratchet prevents backward motion due to external forces like wind or vibration, maintaining the visor's position securely over the user’s face, ensuring impact mitigation without adding discomfort or excess load to the headgear. This proactive face protection unit significantly reduces the risk of facial injuries such as cuts, bruises or fractures during convulsive events, especially when the user falls forward or experiences uncontrolled head movements during epileptic seizures.

[0050] A breathing support module is housed within the face protection unit of the wearable body 101, to stabilize the user’s breathing during seizure-induced respiratory irregularities. The module includes a medical-grade silicone mask 203 is mounted on the inner surface of the fiberglass shield 201 via extendable hollow member 204 that serves as an air delivery channel and connected to a filtered air container 205. When the sensor suite detects abnormal respiratory rates such as hyperventilation or shallow breathing through pressure sensors and data from other biosensors like PPG and EEG, the microcontroller actuates the extendable hollow member 204 that consist of nested tubular sections which slides within each other and is connected to a pneumatic unit that includes an air compressor, a cylinder with a piston and solenoid valve.

[0051] The air compressor generates compressed air, which passes through a solenoid valve and enters into the air cylinder. The air pressure inside the cylinder causes the piston to push the rod outward, causing multiple nested tubular sections to extend and precisely position the mask 203 securely over the user’s nose and mouth as the face shield 201 is deployed. The mask 203 is connected to the filtered air container 205 containing clean, breathable air or supplemental oxygen. The filtered container 205 ensures that the user receives uncontaminated air, even in compromised environments. The airflow actively regulated via a micro-valve that is connected to a miniature DC motor connected to a rotating spindle that adjusts the valve opening. When activated by the microcontroller, the motor precisely rotates the valve, controlling the internal diaphragm to increase or restrict airflow to match the user’s needs during a seizure episode. This helps to stabilize oxygen intake, prevent airway obstruction and reduce the risk of hypoxia or respiratory distress.

[0052] A massaging unit is embedded within the wearable body 101, to provide targeted massage to enhance blood circulation and reduce muscle stiffness, particularly during or after seizure events. The massaging unit includes a plurality of rotary units 107 are placed near major muscle groups such as the shoulders, back and limbs each equipped with a kneading head to stimulate circulation and relax muscle fibers. When the sensor suite detects abnormal muscle activity or tension via EMG sensors or compromised blood flow and low perfusion levels via PPG sensors, the microcontroller actuates the rotary units 107 that consists of a mini DC motor which generates rotational motion and is transmitted through the gearbox to reduce speed and increase torque.

[0053] The gearbox drives an output shaft supported by precision bearings, ensuring stable, low-friction rotation under varying loads. The output shaft is directly connected to the kneading head, which is normally made from soft, skin-safe silicone or elastomer. The controlled torque drives the kneading head in a circular or oscillating motion, enabling to apply dynamic pressure to the body's surface, effectively simulating the pressure and rhythm of a human massage to improve blood circulation and relieve muscle stiffness, thus promoting faster recovery, improving muscular health and reducing discomfort caused by prolonged immobility during seizures.

[0054] A neck and wrist support units are positioned at the back of the collar and wrist sections of the wearable body 101, to provide both physical support and temperature-based muscle therapy. The neck and wrist support units features an expandable cushioned plate 108 made from memory foam or similar adaptive material, which conforms snugly to the user’s neck or wrist contours, ensuring comfort and effective contact. Integrated within these cushioned plates 108 are Peltier unit capable of delivering precise heat or cold therapy. When the EMG sensors detect muscle stress, stiffness or spasms common during or after seizure events, the microcontroller actuates the Peltier unit which works in similar manner to the previously described working of the Peltier module, to transfer heat away from or toward the cushioned plate 108, allowing rapid and localized temperature adjustment that helps relax muscle fibers, reduce inflammation, and alleviate pain. Simultaneously, the microcontroller actuates the expandable cushioned plate 108 that consists of a compact, low-noise mini pump connected to a network of internal air bladders embedded within the memory foam layer of the plate 108.

[0055] When actuated by the microcontroller, the mini pump which consists of a motor drives a diaphragm to cyclically compress within the chamber, generating a pressure differential. This draws in ambient air through an inlet valve and expels through an outlet valve connected to flexible tubing, which channels the compressed air into the internal bladders of the cushioned plate 108 for inflating them accordingly. A control valve regulates the airflow to the inflatable members. As the bladders expand, they cause the cushioned plate 108 to gently enlarge and conform more closely to the user’s neck or wrist, enhancing surface contact and optimizing pressure distribution, further aiding muscle relaxation and improving blood circulation. This combining support addresses both immediate seizure-induced muscle tension and post-seizure recovery needs.

[0056] A battery is associated with the device for powering up electrical and electronically operated components associated with the device and supplying a voltage to the components. The battery used herein is preferably a Lithium-ion battery which is a rechargeable unit that demands power supply after getting drained. The battery stores the electric current derived from an external source in the form of chemical energy, which when required by the electronic component of the device, derives the required power from the battery for proper functioning of the device.

[0057] The present invention works best in the following manner, where the wearable body 101 attached with the cap 102, covers the user’s torso and head and is embedded with impact-absorbing materials for physical protection. The sensor suite monitors real-time vital health parameters, including EEG sensors for brainwaves, PPG sensors for heart rate, bio-impedance sensors for hydration, EMG sensors for muscle strain, EDA sensors for skin conductance, force-sensitive resistors for neck and wrist pressure, pressure sensors for respiration, gyroscopic sensors for movement and temperature-humidity sensors for environmental data. The imaging unit 104 analyzes facial expressions and physical cues to detect seizure indicators. Upon detecting early warning signs, the temperature regulation module uses the Peltier module to control the temperature of the embedded gel layer 106 for thermal comfort. Simultaneously, if seizure onset is confirmed, the face protection unit features the fiberglass shield 201 deployed via the spare visor assembly 202 using the micro-servo motor and ratchet to protect the face. Within this shield 201, the breathing support module includes the medical-grade silicone mask 203, connected to the filtered air container 205 via an extendable hollow member 204, deployed during seizure-induced abnormal breathing. In parallel, the massaging unit, comprising rotary units 107 with kneading heads, activates in response to EMG and PPG inputs to improve circulation and relax muscles. The neck and wrist support units include expandable cushioned plates 108 and Peltier unit for targeted heat or cold therapy respond accordingly. The audio output module 105 provides alerts based on abnormal hydration or vital signs. The input means 103, including the touch display panel and user interface, allows real-time medical data entry and storage in the linked database for further retrieval and analysis.
