Abstract

The Electromyography (EMG) Prosthesis is a prosthetic arm designed to aid an amputee with completing everyday functions. With the use of EMG sensors which reads muscle activity, these results are processed. MyoWare muscle sensors are implemented to measure the filtered and rectified electrical activity of a muscle which are used to control the arm. This data is collected to differentiate the signal or voltages that correspond to different wrist and hand actions. The signal from the MyoWare muscle sensors then feed to a controller the signal and voltage values identified in the previous section and are used to assess each one of the movements necessary for the use of the prosthesis. These movements are then analyzed and communicated through an actuator. The motors pull on a set of strings that act as tendons connected to the moving parts of the hand which then grip the object and also move it along the x and y-axis. The use of EMG muscles sensors in our design result in helping amputees regain their lives, mobility and contemporary normalcy.
