摘要
假肢研究的重点是生理信号的提取和对仿生假手的控制。将肌音信号作为假肢控制的生理信号源,现以放大电路和滤波电路为核心,实现了能采集肌音信号的电路系统设计。通过采集软件,将数据导入Matlab进行特征分析,讨论并验证了电路的全部功能,运用该电路采集到了符合要求的肌音信号。该设计是一种实用的肌音信号前端采集电路。
The research of prosthesis focuses on the acquisition of physiological signal and control of prosthetic limbs.A circuit system with MMG acquisition function is realized,which can use MMG signal as physiological signal source of prosthesis control and adopt amplify circuit and filter circuit.Through the signal collecting software,datas can be imported into Matlab for characteristic analysis.All the function of circuit is tested,the required MMG is collected by the circuit.The design is a practical MMG acquisition circuit.
