摘要
The present invention generally relates to a system and method for fine motor control of fingers on a prosthetic hand. In particular, the present disclosure describes a system and method for controlling the flexion or extension of one or more fingers of a prosthetic hand to reproduce a natural stroke such as for, e.g., writing, painting, brushing teeth, or eating. The systems and methods described herein use electromyographic (EMG) signals and, more particularly, combinations of electromyographic signals, from muscles in the forearm to activate one or more motors of the prosthetic hand that control the motion of the prosthetic fingers. The electromyographic signals may be used to cause fingers of a prosthetic hand to, for example, imitate a writing stroke while the fingers of the prosthetic hand hold a writing utensil. Additionally, the present invention describes electrode placement locations that maximize peak signal detected while maintaining a low base-line signal.
