Abstract: How to acquire and extract surface electromyography (SEMG) expediently and
effectively had been one of the key factors to apply the SEMG. A wireless SEMG acquisition
instrument which was battery powered, storable, high accuracy, easy to operate and convenient to carry was designed, it solved several problems exist in traditional SEMG acquisition instrument well. The usage of FLASH and CP2102 make the instrument storable and convenient to communicate with PC. The system software was designed running in low power mode, and provides several operate ways. The result of application showed the feasibility of the method described in the paper.
