A microcomputer-based prosthetic limb controller: design and implementation

This paper describes the design and implementation of a microcomputer based myoelectric limb controller. This controller was constructed for use as a feasibility study of, and a development tool for, microcomputer-based myoelectric limb controller applications. Features of this approach include flexibility and computational power. The present design uses low-power CMOS technology to provide a system in which most of the new computationally and decision orientated myoelectric signal processing algorithms can be used. Two CMOS microprocessors, a CD80C86 and a MC146805E2, are used, but microcomputer power consumption is only 120 mA.
