Abstract

The project focuses on the development of a small, water-proof elecromyographic (EMG) sensor for a myoelectric arm prosthesis that transmits by a wireless link and can be easily and consistently installed over any muscle site. The wireless link eliminates wires and connectors inside the arm socket that can be bulky and unreliable due to corrosion and breakage of wires representing a significant improvement in prosthetic arms affecting both patient and prosthetist. Designs allow for fast and reliable mounting that improve the consistency of contact with the skin. The digital processing of EMG greatly improves EMG dependability by allowing more effective filtering for elimination of interference and noise, an ever-increasing problem in the age of cell phones and electric motors.
