Description:An identifiable feature of the wearable module is the tri-lobed structural configuration that is specifically designed to receive high-fidelity signal acquisition.
1. Motion Artifact Suppression: The three-lobed base frame offers distributed mechanical tension to the human torso to eliminate sensor movement when the user moves.
2. Hybrid Fabrication Materials: The enclosure is fabricated using a rigid PLA (Polylactic Acid) shell for protecting internal electronics, integrated with elastic TPU (Thermoplastic Polyurethane) straps. And the TPU components offer essential damping of vibrations that further stabilize the sensor interface.
3. Anatomical Synergy: The concave (anatomically shaped) bottom provides the MAX30102 PPG sensor with a consistent zero-gap interface to the skin. The physical architecture is a mechanical filter of the “noise” that directly allows R2 values exceeding 0.99
, Claims:1. A health monitoring system for automated emergency detection, the system comprising:
• A wearable module having a tri-lobed base frame and a concave underside configured for three-point mechanical stabilization on a human torso;
• A sensor suite comprising a physiological biosensor (PPG), an inertial sensor, and an ambient PIR sensor, all interfaced with a central processor;
• The processor is configured to perform multimodal sensor fusion by correlating internal physiological data with external environmental and impact data to trigger an alert.
• Characterized in that the tri-lobed frame maintains constant skin-to-sensor contact pressure to minimize motion artifacts during data acquisition.
2. The system as claimed in claim 1, wherein the concave underside is anatomically contoured to match thoracic curvature, enabling the biosensor to achieve a heart rate correlation of at least R2 = 0.99 relative to medical-grade devices.
3. The system as claimed in claim 1, wherein the wearable module is fabricated from a hybrid material configuration comprising a rigid PLA housing and elastic TPU straps, wherein the TPU straps provide mechanical vibration damping for the biosensor.
4. The system as claimed in claim 1, wherein the processor triggers an emergency alert only upon concurrent detection of a high-G impact, abnormal physiological vitals, and a lack of motion detection via the ambient PIR sensor.
5. The system as claimed in claim 1, wherein the processor is configured for edge-processing, whereby physiological data is processed locally to ensure privacy-preserving monitoring, and a GPS module is activated to transmit coordinates only when an emergency alert is triggered.
6. The system as claimed in claim 1, further comprising a tactile SOS button interfaced via digital GPIO pins of the processor to provide a manual override for initiating the alert protocol.
