摘要
设计了一款基于STM32的便携式生物反馈与电刺激仪,适用于临床功能复健、肌肉力量强化训练等场合。针对肌电信号的特征,设计了硬件信号处理电路,具备采集输入和刺激输出的双工模式;采用时域分析方法提取肌电信号的特征值,利用串口通信实现屏幕显示及人机交互功能;整机具有灵活便携、操作简单等特点,并通过系统测试验证了方案的可行性。
Portable biofeedback and electrical stimulator based on STM32 is designed,suitable for clinical functional rehabilitation,muscle strength training and other occasions.Aiming at the characteristics of the EMG signal,signal processing circuit is designed with a duplex mode for capture and stimulus;the method of time domain analysis is used to extract the eigenvalues of EMG signal;serial communication is used for screen display and human-computer interaction;the instrument is flexible,portable and simple to operate;the design is verified and feasible by system testing.
