For our final project, we built a surface electromyograph to collect and analyze data on muscle activity, which supports two channels, implements wireless transmission, and can be worn as mobile unit. Surface electromyography (EMG) is a noninvasive technique to record the activation signals of muscles when they are mechanically active. This signal is very small compared to the 60 Hz signal which appears on the human body from power systems. Wireless was employed to safely isolate the human body from 120V power supply and ground. The system takes data from a small, mobile transmission unit and outputs and stores data into Matlab for future analysis. Disclaimer: This device is a student project NOT a medical device. Do not ground the transmitter unit while attached to body! Use at your own risk!
