Abstract

A low-cost wireless surface EMG acquisition system has been designed for general purpose human-machine interaction. The system includes disposable surface EMG sensors, wireless communication using Bluetooth modules and signal analysis unit. Surface EMG acquisition system has been developed for the measurement of electrical activity of muscles and validates the design prototype of lowest wireless acquisition system. Generally, Bluetooth has an advantage which is almost ubiquitous technology and universally compatible and a wide variety of devices employ it. In this study, the system uses three channels of electrodes that sense muscles activity potential in microvolt and was wireless to transferred to the device with limitation 1kb per seconds. The low cost wireless was design using Bluetooth module. Its EMG signal is friendly and also reliable for users with high flexibility in being significant proposition in modern biomedical engineering surrounding. All through the process, the signal was acquisited from muscle activity. Besides that, the implementation of designing the command to configure the signal obtains to be transmitted to the computer’s software using MATLAB and software of ARDUINO.
