DEVELOPING PROSTHETIC ARM USING ELECTROMYOGRAPHY (EMG) SYSTEM

Abstract

Prosthetic limb was very beneficial to amputee patient but statistic shown that most of amputee decline to use the prosthetic limb offered because of higher cost and cause back pain due to heaviness of the prosthetic limb. The first goal for this project was to develop prosthetic arm using Electromyography (EMG) sensor. The second goal is to monitor the muscle activities and performance of the current prosthetic limb. The prosthetic arm is using embedded system that build in together with the EMGsensor and data logging. The main part of this project is the 3D printed prosthetic arm using PLA white color, 200 micron and above material. Other hardware used for this project are Arduino Mega and servo motor. As mention before, EMG sensor with three electrodes are used to detect muscle energy. This project software is using Arduino IDE and PLX-DAQ for codding and data logging process. Each software is able to act as data logging purpose. Arduino Mega will send data of muscle signal that beencollected by EMG sensor to servo motor that attached to prosthetic arm fingers. The result shown the amount of muscle signalproduces when muscle is relaxed and contracted. This system provided real-time data to patient. This will make patient able tomonitor the muscle energy used while using theprosthetic arm.
