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.

A low-power multichannel electromyographic signal data acquisition system.

The development of a stand-alone low-power EMG data acquisition system is described. The resulting design operates at low power (approximately 350 mW) and gives four channels of signal measurement with a maximum sampling rate of 10 kHz. Therefore, the data acquisition system described is ideal for low power data acquisition using a microcomputer. The digitized results are available to the microcomputer in a 12 bit signed magnitude form. This system was designed and implemented for use in a microcomputer-based myoelectric limb controller, however, its use is not limited to this application.
