Design and Implementation of a Sitting Posture Analysis System Based on Pressure Sensors and Flexible Silicone Materials

Modern healthcare technology is developing to monitor and improve a personal health in real time and among them, body data analysis using pressure sensors is attracting attention.FSR-based pressure sensors are limited by low sensitivity, poor precision, and insufficient durability, which restricts their use in precise data analysis.In this suudy, to overcome these limitations, we designed a multi-channel pressure sensor using silicone flexible material, and attempted to improve durability by increasing mechanical strength through combination with neoprene material.Experimental results demonstrated the sensor's linearity in pressure and resistance changes, as well as its wide sensing range than existing sensors.Furthermore, a sitting posture analysis system was implemented based on the designed sensor, demonstrating its practical applicability in healthcare and wearable device fields.
