基于柔性力敏传感器的便携式坐姿监测与提醒系统

读写坐姿长时间不规范将对青少年身体健康、学习效率产生不利影响.本文基于柔性力敏传感器，设计了一套新型的便携式读写坐姿实时监测及智能提醒系统.该系统根据生物力学、人体工程学规律，通过铺设于座椅上40 cm×40 cm的柔性力敏传感器，采集坐立时臀部压力分布数据。首先对原始数据进行预处理，再通过所提出的坐姿动作识别与分析算法对坐姿状态进行识别，实时分析坐姿情况，最后结合环境的温度、湿度、光强参数，给出预警方案.同时，在手机APP客户端实时显示并且存储监测期间坐姿及环境变化情况.该系统设计简单、交互性强，借助手机和压力垫的便携性，方便用户达到实时预警和分析的效果，帮助青少年纠正不良坐姿.

Portable Sitting Position Monitoring and Warning System Based on Flexible Force-Sensitive Sensor

The improper sitting posture of reading and writing can have a serious effect on the health and learning efficiency of the young. This study designed a new type of portable, real-time monitoring, and intelligent reminder system of the writing and the reading sitting posture. According to the biomechanics and ergonomics rules, the system uses 40 cm×40 cm flexible force-sensitive sensors to collect sitting pressure distribution data, combined with environmental parameters to analyze results in real time. Meanwhile, the sitting position and environment change are displayed during the monitoring period in real time via the mobile phone APP. The system is easy to understand and interactive, which can help teenagers to correct improper sitting postures. With the convenience of mobile phone, it is convenient for users to achieve real-time warning and analysis.
