Surface electromyography(sEMG)is a bioelectrical signal generated during muscle movement,and it is an important non-invasive method for detecting muscle activity on the body surface.It is designed a muscle electro-myography acquisition device which can transmit multi-channel sEMG signals to a computer by wireless mode,and displays them used the upper computer interface.The muscle signal acquisition circuit implements pre-processing such as amplification and filtering to capture weak muscle signals,enabling data acquisition and wireless transmis-sion.The single-chip microcomputer is responsible for data acquisition and packet processing,and transmits the data to the computer according to a wireless protocol.The upper computer interface receives the data packets,par-ses and extracts useful information,and displays the muscle signal waveform.By attaching this acquisition device to the surface of the muscles,the movement status information of the muscles can be transmitted to the computer for analysis.
