Abstract
This paper design an acquisition instrument of surface EMG (SEMG)based on a high common mode rejection ratio(CMRR) preamplifier to deal with the difficulties in capturing the SEMG which is small range,low SNR,easy to be disturbed and the high prices of present acquisition equipment.This design can restain the common mode interferrence and power frequency interferrance effectively with a low price.By making use of wireless communication module PTR2000 in connecting C8051F320 MCU to host computer for data transmission,a wireless real-time acquisition system of SEMG is constitued.The complete and accurate SEMG is obtained in the host computer,providing a reliable source for the further analysis and processing of SEMG.
