Description:FIELD OF THE INVENTION

[0001] The present invention relates to a wearable safety device for worker protection and real-time health monitoring that is developed to improve worker safety and health by offering a wearable gear that monitors physical condition, detects signs of fatigue or risk, and actively responds to enhance protection, comfort, and awareness during operations in hazardous or demanding environments.

BACKGROUND OF THE INVENTION

[0002] In industrial workplaces, mining sites, construction areas, and other high-risk environments, worker safety and health monitoring are of critical importance. Workers are often exposed to physically demanding tasks, extreme environmental conditions, and prolonged working hours. These factors leads to fatigue, health deterioration, accidents, and sometimes even life-threatening situations. Workers are required to operate heavy machinery, work at heights, or handle dangerous materials, all of which demand constant alertness and good physical condition. However, traditional safety measures often rely on passive protective gear and manual supervision, which may not be enough to address real-time risks.

[0003] Traditionally, worker safety and health have been addressed using separate protective gear and standalone health monitoring devices. For example, workers wear helmets, gloves, safety boots, and reflective jackets to guard against physical injuries, while separate wearable devices such as smartwatches or wristbands are used to track heart rate and movement. In some workplaces, supervisors rely on visual checks or manual reporting to monitor signs of fatigue or drowsiness. These conventional methods are not integrated, often lack real-time responsiveness, and do not provide complete coverage of the worker's health or environment. Additionally, traditional safety gear does not adapt to the worker’s physical state or provide active feedback when abnormal conditions are detected.

[0004] Another limitation of existing devices is the lack of automated alert mechanisms and adaptive responses. Most devices are not able to detect and respond to drowsiness, abnormal postures, or hazardous biometric readings in real time. Technologies like headgear or clothing do not include motion-based sensor realignment or pressure adjustments, thus fall short in providing continuous, proactive, and personalized protection for workers operating in high-risk settings.

[0005] CN106493715B discloses a kind of exoskeleton devices for exposure suit support, are mainly made of shoulder mechanism, waist mechanism and leg.Including a pair of of back supporting bar, the fixed transverse rod being arranged between back supporting bar and guide part and the flexible harness of a pair being fixed in back supporting bar, waist mechanism includes two straight tube shape tension spring leg mechanisms that lumbar support bar, the flexible waistband being mounted on lumbar support bar and one end are separately fixed at left and right sides of lumbar support bar, the thigh support straight-bar including automatic switching control equipment upper end is arranged in；Automatic switching control equipment between thigh support straight-bar and leg support straight-bar is set.The exoskeleton device is pure passively support construction, the support and power-assisted at each movable joint position are realized using spring and hinge, kneed spring_slide structure can also realize the switching of support modes, no matter in guard station operation, squat down operation or nature walking states all show good effect.

[0006] KR20060115349A discloses single activity protector (20, 30) extends from one side of the breast above the sternum to the other, the garment comprising a plurality of means for protecting the upper part of the body against trauma and fracture due to falling or impact on obstacles.

[0007] Conventionally, many devices and protective methods are available for physical safety or limited health monitoring. However, these devices operate independently either to protect the body or to check health signs. These devices usually work on their own and are not connected with each other. This causes safety gaps, especially when it comes to spotting health problems like tiredness, overheating, or sleepiness while working. Most of these devices do not give any warning or physical alert to the worker or inform a supervisor when something is wrong that leaves the workers at risk of accidents.

[0008] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to be capable of providing a protective wear with real-time health monitoring, alert mechanisms, and responsive features in view of preventing accidents caused by fatigue, inattention, or adverse physiological conditions. The device must also detect the signs of drowsiness to ensure worker awareness and safety for seamless protection and comfort during varied work conditions.

[0023] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0024] The present invention relates to field of personal protection. More specifically, a wearable safety device for worker protection and real-time health monitoring that identifies health parameters or safety concerns of the user in real time, and reacts to mitigate risks, thereby supporting safe, efficient, and sustained work in physically challenging or high-risk settings.

[0025] Referring to Figure 1, an isometric view of a wearable safety device for worker protection and real-time health monitoring is illustrated, comprising of a wearable body 101 configured to cover a user's upper and lower body and integrated with a cap 102, gloves 103, sleeves 104, and shoes 105, an artificial intelligence-based rotating camera 106 mounted on the body 101, an iris ring 107 integrated within a rim of the cap 102, a chamber 108 embedded within a portion of the body 101 connected to a dispensing nozzle 109, a pair of extendable telescopic bars 110 configured between the cap 102 and collar and between the shoes 105 and lower end of the body 101 via motorized ball-and-socket joints 111, a motorized slider 112 provided on bodies portion of the body 101 and integrated with a motorized roller 113, the alert unit comprises of one speaker 114, and a biometric scanner 115 is integrated with the body 101.

[0026] The present invention discloses a wearable body 101 that is developed to be worn by a user to keep the user safe and alert in a working environment. The body 101 includes a cap 102, sleeves 104, gloves 103, and shoes 105 for covering the entire body 101 of the user for complete safety.

[0027] The body 101 herein consists of multiple protective layers including heat-resistant, fire-resistant, puncture-resistant, UV-resistant, and impact-absorbing materials to safeguard the user from hazardous environments. The heat-resistant layer is configured to protect the user from high-temperature environments by preventing the transfer of external heat to the user's body. The heat-resistant layer works by using materials with low thermal conductivity, such as aramid fibers or treated fiberglass, which slow down the transfer of external heat to the user’s body.

[0028] The fire-resistant layer is designed to reduce the risk of injury from direct flame exposure or fire-related incidents. The fire-resistant layer operates through chemically treated or inherently flame-retardant materials that resist ignition, and when exposed to flame, they char instead of melting or dripping, creating a protective barrier that slows down combustion and limits fire spread.

[0029] The puncture-resistant layer serves to protect the user from sharp objects, tools, or debris that could otherwise pierce through standard clothing. The puncture-resistant layer that distribute and resist the force of sharp objects. When a pointed object attempts to penetrate the material, the fibers absorb and spread the energy across a wider area, preventing penetration and minimizing localized damage.

[0030] The UV-resistant layer functions through the use of fabrics coated or embedded with UV-blocking agents, such as titanium dioxide or specific polymer treatments. These agents reflect or absorb ultraviolet rays, preventing them from passing through the material and reaching the skin. The layer maintains its effectiveness even under prolonged sun exposure, reducing the risk of UV-related skin damage.

[0031] The impact-absorbing layer is integrated to minimize the force of sudden impacts or collisions by using shock-absorbing materials such as foam or gel structures to cushion the user’s body against blunt force, thereby reducing the risk of injury in environments with moving machinery, falling objects, or accidental contact with hard surfaces. When subjected to sudden force or impact, the material compresses to absorb kinetic energy, reducing the amount of force transferred to the body 101. Once the impact is over, the material returns to its original shape, ready for reuse without permanent deformation.

[0032] Once the user wears the body 101, the user is required to access and presses a push button arranged on the body 101 to activate the device for associated processes of the device. The push button when pressed by the user, closes an electrical circuit and allows currents to flow for powering an associated microcontroller of the device for operating of all the linked components for performing their respective functions upon actuation.

[0033] The body 101 is integrated with a plurality of sensors that work collaboratively for continuous detection of detecting health parameters and physical activity of the user. The sensors include a pulse sensor, temperature sensor, EEG sensor, proximity sensor, gyroscope, IMU (Inertial Measurement Unit), accelerometer, and a PPG (Photoplethysmography) sensor.

[0034] The wearable body 101 includes a pulse sensor configured to continuously monitor the user’s heart rate. The pulse sensor works on the principle of photoplethysmography that emits light (usually from an LED) onto the skin, and a photodetector measures the amount of light reflected or absorbed by the blood flowing through the capillaries. With each heartbeat, the volume of blood in the vessels changes, altering the amount of reflected light. The sensor records these changes as pulse waves to determine the heart rate and sends a signal the microcontroller.

[0035] The temperature sensor operates by measuring the thermal radiation emitted by the user’s skin or through direct contact by using a thermistor or infrared sensing element to detect temperature changes. When the user's body temperature rises or falls, the resistance in the thermistor changes, which is then converted into a digital temperature reading. This data is used to detect signs of heat stress, fever, or hypothermia, especially in extreme working environments.

[0036] Based on the detected temperature readings, a Peltier module fabricated within a thermal gel patching layer provided on inner portion of the body 101, works in conjunction with the temperature sensor to maintain user’s body temperature within a safe range. The Peltier module works on the principle of the Peltier effect, where electrical current is used to create a temperature difference across two sides of the module. The microcontroller activates the Peltier module, and depending on the requirement, the module either absorbs heat from the body 101 to cool it down or releases heat to warm it. The thermal gel layer helps distribute this temperature change evenly and comfortably over the skin.

[0037] The electroencephalogram (EEG) sensor works by placing electrodes on the scalp to detect electrical activity produced by neurons in the brain. These electrical signals are picked up as voltage fluctuations and analyzed for different frequency bands (e.g., alpha, beta, delta, theta waves), which correspond to different mental states. The sensor sends this data to the microcontroller to assess the user’s alertness level and activate alerts if needed.

[0038] The proximity sensor detects the presence of nearby objects without physical contact that works using infrared (IR), ultrasonic, or capacitive technology. The IR device emits an infrared beam and measures the time or intensity of the reflected signal to determine object distance. This allows the device to detect when the user is too close to hazardous objects or machinery, helping prevent collisions or accidents.

[0039] The gyroscope works by detecting angular velocity or rotational movement around one or more axes that uses MEMS (Micro-Electro-Mechanical Systems) that consists of a vibrating mass that shifts in response to angular motion. The changes in vibration are measured and sent as a signal to the microcontroller that processes the signal into angular rate data. The gyroscope provides information about the user’s head and body orientation, which helps detect sudden posture changes, instability, or risk of falling.

[0040] The IMU (Inertial Measurement Unit) combines data from a gyroscope and accelerometer to track movement and orientation in 3D space. The accelerometer measures linear acceleration, while the gyroscope captures angular velocity. Together, these readings are processed to determine the user’s motion pattern, posture, balance, and direction for monitoring user’s body dynamics and detecting abnormal motion that may indicate fatigue or imbalance.

[0041] The accelerometer detects acceleration forces acting on the user in different directions (X, Y, and Z axes) that uses internal capacitive or piezoelectric elements that change electrical output when subjected to motion or vibration. The sensor captures sudden movements such as walking, running, falling, or stillness and sent as a signal to the microcontroller to analyze physical activity levels and detect irregularities that may suggest fatigue or risk of accidents.

[0042] The PPG (Photoplethysmography) sensor operates by emitting light, usually in the red or infrared spectrum, onto the skin using LEDs. The light penetrates the skin and reflects off blood vessels, where a photodetector measures changes in light absorption caused by blood volume variations with each heartbeat. The sensor calculates pulse rate and oxygen saturation levels (SpO2) to detect poor circulation, oxygen deficiency, or physical stress.

[0043] Along with detection of the biometric parameters and physical activity of the user, an artificial intelligence-based rotating camera 106 is mounted on a collar portion of the body 101 to capture facial expressions and movements of the user. The camera 106 is equipped with AI protocols trained to recognize facial expressions, eye movements, and blinking patterns that are indicative of fatigue, drowsiness, or reduced alertness. The camera 106 also tracks the orientation and position of the user's head to detect signs such as nodding, drooping, or lack of movement, which signal inattention or micro-sleep. The camera 106 rotates automatically to maintain focus on the user's face, ensuring accurate monitoring regardless of head position. Based on the visual data, the microcontroller assesses cognitive alertness and sends signals if abnormal patterns are detected, prompting immediate alerts or interventions.

[0044] The microcontroller receives data from plurality of sensors and the camera 106, and upon detection of drowsiness symptoms, the microcontroller actuates a plurality of alert units provided on the body 101 for alerting the user and notifying a remote supervisor. The alert unit comprises of at least one speaker 114, one vibration unit, one fragrance nozzle 109, and a plurality of LED indicators.

[0045] The alert unit preferably comprises of a speaker 114 integrated within the wearable body 101 to provide real-time audible alerts. The speaker 114 works by converting the electrical signal into the audio signal. The speaker 114 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, generating a varying magnetic field that interacts with the magnet causing the diaphragm to move back and forth. This movement pushes and pulls air creating sound waves just like the electrical signal received and used to notify the user to immediately regain the user’s attention and prevent lapses in focus during critical tasks.

[0046] The alert unit may also include a vibration unit positioned within the wearable body 101 near high-contact areas such as the chest, arms, or shoulders. The vibration unit consists of a motor-driven mechanism that generates mechanical oscillations when activated. When the microcontroller identifies signs of fatigue or inattention, or prolonged eye closure, it triggers the vibration motor, serving as a discreet but effective alert method, particularly in environments where sound-based alerts might be ignored or go unnoticed.

[0047] A fragrance nozzle 109 connected to a sealed chamber 108 containing a liquid with an unpleasant or sharp scent, such as ammonia-based compounds is used for alerting the user. The nozzle 109 is electronically controlled by the microcontroller and is placed in a position where the released scent is quickly perceived by the user. When the microcontroller detects a high level of drowsiness or unresponsiveness, the microcontroller actuates a valve to dispense a small amount of the fragrance into the air near the user, encouraging the user to regain alertness quickly without physical contact or sound.

[0048] Further, the alert unit may comprise of plurality of LED (light emitting diode) indicators strategically located on the outer surface of the wearable body 101 for maximum visibility. LED are made from semiconductor materials which have properties that allow them to emit light. The LED contains a p-n junction, where a p-type region is positively charged and an n-type region is negatively charged. When voltage is applied, electrons from the n-region move towards the p-region, and holes from the p-region move towards the n-region. As the electrons move across the p-n junction, they recombine with the holes. During this process, the electrons lose energy, and this energy is released in the form of photons (light) for offering a visual cue of the user’s physical state or alertness level.

[0049] The microcontroller also stores and manages historical health information of the user in a dedicated database and collects biometric readings such as heart rate, temperature, activity levels, and EEG patterns in view of creating a personalized health profile for the user. Using this data, it learns the user’s normal physiological responses and work patterns to dynamically adjust drowsiness detection thresholds based on individual tolerance and stress levels. This personalized calibration helps reduce false alerts and improves accuracy. Additionally, by analysing accumulated data on work duration, physical strain, and fatigue indicators, the microcontroller recommends rest or hydration breaks to prevent exhaustion, enhance productivity, and reduce the risk of health-related incidents during long tasks.

[0050] The rim of the cap 102 of the body 101 is configured with an iris ring 107, actuated by the microcontroller to adjust diameter of the cap 102 in view of ensuring a snug and customizable fit according to a wearer’s head size, as determined by the artificial intelligence-based rotating camera 106. The artificial intelligence-based rotating camera 106 works in the similar manner as described earlier.

[0051] The iris ring 107, mentioned herein, consists of a ring 107 in bottom configured with multiple slots along periphery, multiple number of blades and blade actuating ring 107 on the top. The blades are pivotally jointed with blade actuating ring 107 and the base plate are hooked over the blade. The blade actuating ring 107 is rotated clock and antilock wise by a DC (Direct current) motor embedded in ball actuating ring 107 which results in opening of the iris ring 107 to adjust the cap according to wearer’s head size and comfort preference.

[0052] The cap 102 is attached to the body 101 via a pair of extendable telescopic bars 110, actuated by the microcontroller to ensure precise fit according to user’s body posture and motion data as detected earlier by the sensors and camera 106. The telescopic bars 110 are powered by a pneumatic unit that includes an air compressor, air cylinder, air valves and piston which works in collaboration to aid in extension and retraction of the bars 110.

[0053] The pneumatic unit is operated by the microcontroller, such that the microcontroller actuates valve to allow passage of compressed air from the compressor within the cylinder from one end, the compressed air further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the bars 110 and due to applied pressure the bars 110 extends and similarly, the microcontroller retracts the bars 110 by pushing compressed air via the other end of the cylinder, by opening the corresponding valve resulting in retraction of the piston, and the retraction of the rod. Thus, the microcontroller regulates the extension/retraction of the bars 110 to ensure ergonomic fit and sensor alignment.

[0054] The bars 110 are configured with the cap 102 via motorized ball-and-socket joints 111 for comfortable and ergonomic fit. The motorized ball and socket joint 111 allows for smooth, adjustable movement in various directions. The joint 111 has a ball-shaped part that fits into a cup-like socket. A motor controls this ball, making the ball move around inside the socket. Actuators adjust the ball’s position to ensure it moves accurately and flexibly, enabling precise control and positioning of the cap 102 in multiple directions for sensors alignment.

[0055] The cap 102 is layered with a dual-layer structural filled with a non-Newtonian fluid between the dual layers. In case the drowsiness is detected to be exceeding a predefined threshold by the artificial intelligence-based rotating camera 106, the microcontroller triggers the non-Newtonian fluid to change viscosity to provide a controlled reaction, providing a pressure-based stimulus.

[0056] The non-Newtonian fluid works by altering its viscosity in response to applied force or motion. In the cap’s 102 dual-layer structure, the fluid remains soft under normal conditions for user comfort. When drowsiness is detected, the microcontroller activates a stimulus, such as vibration that causes the fluid to stiffen temporarily. This change in consistency creates a controlled pressure to alert and awaken the wearer in response to the excessive drowsiness.

[0057] To ensure the user is alert during the drowsiness phase, the microcontroller actuates a dispensing nozzle 109 configured with a chamber 108 embedded within a portion of the body 101 for releasing the unpleasant fragrance, when the drowsiness level exceeds a predetermined threshold when compared to a pre-fed database linked to the microcontroller. The nozzle 109 is a mechanical device designed to control the flow, direction, or speed of unpleasant fragrance as it is dispensed from the chamber 108. The nozzle 109 consists of a tapered or constricted opening that directs the flow of the material, converting pressure into velocity. When unpleasant fragrance enters the nozzle 109, it accelerates through the narrowed opening, increasing in speed while decreasing in pressure and released in proximity to the wearer to stimulate alertness.

[0058] To counter the drowsiness or anomaly when detected beyond a predefined threshold, the wearable body 101 includes a motorized slider 112 and motorized roller 113 assembly that operates in coordination to provide adaptive mobility and protective coverage to the user's hands or arms. A length of fabric is wound onto the motorized roller 113, and its free end is fixed to the sleeve 104 portion of the wearable body 101.

[0059] The roller 113 is powered by an electric motor that rotates the roller 113 to pull the fabric inward, while the slider 112 ensures uniform tension and alignment during the retraction process. The motorized slider 112 is mounted on a guided track along the body 101 portion and is driven by a motor. When drowsiness or physical anomaly is detected, the microcontroller simultaneously activates the roller 113 and slider 112. The roller 113 begins retracting the fabric, while the slider 112 moves along the track, pulling the fabric evenly and guiding its path to avoid tangling or misalignment. This synchronized action ensures smooth and controlled retraction of the fabric over the user's arms or hands, offering physical support or added protection.

[0060] In addition, the gloves 103 of the body 101 are embedded with pressure sensors and motion sensors to detect fatigue-related hand tremors. The pressure sensor functions by detecting variations in force applied by the user’s hands during movement or grip. The sensor uses a piezoresistive sensing, where pressure on the glove 103 surface causes a measurable change in electrical resistance. These changes are continuously monitored by the microcontroller to assess grip strength and pressure patterns. When fatigue sets in, the user's grip may weaken or become inconsistent, which is reflected in the pressure data. This helps identify early signs of physical strain or muscle fatigue in the hands.

[0061] The motion sensor includes an accelerometer or gyroscope that detects movement and orientation of the hands. The sensor records the speed, direction, and frequency of hand motions. When a user experiences fatigue, involuntary hand tremors or a decrease in motion precision occurs. The motion sensor captures these subtle tremors or irregularities in hand movement, sending the data to the microcontroller for analysis. If patterns consistent with fatigue-related tremors are identified to enhance user safety and ensure sustained hand performance during physically demanding tasks.

[0062] To combat the strain-related hand gestures, the gloves 103 have a lining of an anti-slip grip lining to prevent strain. This lining is made from high-friction, durable materials that enhance the user's grip on tools, machinery, or other objects. By minimizing the need to exert excessive force to maintain a firm hold, the anti-slip surface helps reduce muscular effort and prevents fatigue in the hands and fingers, ensuring a secure and stable grip in various working conditions.

[0063] The microcontroller is integrated with a GPS (Global Positioning System) module that functions by receiving signals from multiple satellites orbiting the Earth to determine the precise geographic location of the user. The module calculates the user's coordinates (latitude, longitude, and altitude) by measuring the time it takes for signals from at least four satellites to reach the device. Once the location data is obtained, it is processed by the microcontroller and automatically transmitted to a computing unit of supervisor’s and concerned authorities.

[0064] A communication module facilitates data exchange between computing unit and microcontroller by encoding and sending information over various channels, such as Wireless Fidelity (Wi-Fi), Bluetooth, or cellular networks. The communication module, such as a Wireless Fidelity (Wi-Fi) module connects to the microcontroller to wirelessly transfer data to the computing unit, like a smartphone or server, over a Wi-Fi network. The microcontroller sends the data via the Wi-Fi module to a remote server or cloud service using standard communication protocols (such as HTTP or MQTT). The computing unit then processes the data and sends an alert (such as a notification or email) to computing unit to alert the supervisor and concerned authorities.

[0065] The body 101 is integrated with a biometric scanner 115 to capture unique biological traits of the user, such as fingerprint, iris pattern, or facial features. When the user attempts to access the device or enter a restricted zone, the scanner 115 collects real-time biometric data and sends it to the microcontroller. The microcontroller then cross-references this input with pre-stored biometric records in a linked database. If the identity and authorization status match, access is granted; otherwise, access is denied. The scanner 115 works by using optical or capacitive sensors to detect and digitize the biometric trait, ensuring secure, accurate user identification. This enhances operational safety, prevents unauthorized usage, and supports secure workplace access control.

[0066] The shoes 105 are configured with the body 101 with the help of a pair of extendable telescopic bars 110 configured between the shoes 105 and lower end of the body 101 via motorized ball-and-socket joints 111. The extendable telescopic bars 110 and motorized ball-and-socket joints 111 work together in the similar manner as described earlier for the positioning of the cap 102.

[0067] The shoes 105 of the body 101 are integrated with a motion tracking unit to monitor and adjust according to the user’s walking patterns and foot movements in real time. This unit includes a combination of sensors such as accelerometers, gyroscopes, and pressure sensors embedded within the structure of the shoes 105. These sensors work in the similar manner as described earlier to detect parameters such as step frequency, gait cycle, foot angle, and ground impact force. The collected data is sent to the microcontroller, which analyses the movement. Based on the detected parameters, the microcontroller adjusts alignment of the shoes 105 that helps maintain proper foot positioning, enhances walking stability, and reduces stress on joints and muscles.

[0068] A battery (not shown in figure) is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrodes named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0069] The present invention works best in the following manner, where the wearable body 101 is worn by the user to cover the entire body by means of the cap 102, gloves 103, sleeves 104, and shoes 105, included with the wearable body 101, in view of ensuring physical protection. Upon activation, the plurality of sensors embedded in the wearable body 101 begin continuously monitoring the user's health parameters and physical activity of the user. These include vital signs such as pulse rate, body’s temperature, motion, proximity, and EEG patterns, which are collected and processed by the microcontroller. Simultaneously, the rotating camera 106 mounted on the collar tracks facial expressions and head movements to detect signs of drowsiness in real time. Based on this data, the microcontroller evaluates the user’s state and, when abnormal signs or symptoms of fatigue are detected, it triggers a coordinated response through the alert units. To further address drowsiness, the dual-layered cap 102 utilizes a non-Newtonian fluid, which increases viscosity upon activation to apply controlled pressure as a physical stimulus. In parallel, the Peltier module, in coordination with the temperature sensor, maintains a safe body 101 temperature by heating or cooling the internal surface of the body 101 suit.

[0070] In continuation, for adaptive fit and sensor realignment, motorized telescopic bars 110 between the cap and collar and shoe 105 and body 101 areas adjust based on posture and motion data. When fatigue is detected in the arms or hands, the motorized roller 113 and slider 112 mechanism retracts a connected fabric onto the user’s sleeves 104, providing additional support or coverage. The gloves 103 help detect hand tremors using embedded pressure and motion sensors, while the anti-slip lining reduces muscular strain during tool handling. The microcontroller further records and stores historical health data to analyze physical stress and working patterns over time, automatically adjusting drowsiness thresholds and suggesting rest or hydration breaks. The integration of a GPS module ensures real-time location tracking, allowing supervisors to monitor worker safety remotely. For security and controlled access, the biometric scanner 115 verifies the user's identity before enabling device functions or access to restricted zones.
