基于FSR的可穿戴式足底压力检测系统

摘要

Plantar pressure information is significant to human health assessment and certain diseases forecast. An implementation method of wearable plantar pressure detecting system is presented. With full consideration of convenience and low power consumption demand for wearable detecting tools, slice type force sensing resistor (FSR)and low power consumption micro devices are used,and the entire system is integrated into the insole, which is small and has practical function. Experimental results show that the plantar pressure detection system can real-time collect plantar pressure signal and display pressure waveform on computer, and the system has good sensitivity,accuracy,wearable,low power consumption,which meets the actual needs for plantar pressure detection and human gait analysis%足底压力信息的研究对人体健康状况评估和某些疾病预测具有重要意义.提出了一种可穿戴式足底压力检测系统的实现方法.该方法充分考虑了穿戴式检测工具的方便灵活和低功耗要求,采用薄片式力敏电阻器(FSR)和低功耗微小器件,将整套系统集成于鞋垫中,体积小巧,功能实用.实验结果表明:介绍的系统可以实时采集足底压力信号并在计算机上显示压力波形,系统有较好的灵敏度、准确性和可穿戴性,低功耗运行,满足足底压力检测和人体步态分析等实际需要.
