MYOELECTRIC ARM – FOR THE HALF LIMB AMPUTEE

Abstract: As the technology around us is attaining a fast pace, we are working towards extending this fast growing technology to help people with half amputation by attempting to make a prototype which will enable the amputees to lead a normal life. Myoelectric Arm is a prosthetic aid which will help the amputee in grasping objects. A prosthetic is an artificial part of the functional human body which is life less and does not support any mechanical movement. This device will bring this prosthetic into function by using myo-electrical energy as the source. This is done primarily by attaching the servo motor to the prosthetic, and then servo is initiated by the patient’s own muscle contractions or by the muscle twitch. The biggest challenge is myo-electric signals. The electric current generated by these muscle contractions is then amplified by means of an E-shield which can support an Arduino microcontroller and with the help of supporting and storage batteries to control the terminal device. Such an arrangement is referred to as a myoelectrical control system. The main objective of the project is to make a cost effective, sophisticated, miniaturized and an appealing prototype of a myoelectric arm with long duration of time and battery life, which enables amputees to feel completed and use both their limbs normally as they did earlier.
