A Surgically Implanted Myo-telemetry Unit

Abstract

An implanted telemetry unit suitable for myo-electric control is described. This unit is similar in function to one reported previously, but incorporates significant improvements. 

Designed for long-term use, the unit is powered by electro-magnetic coupling at radio frequencies. This allows construction of a unit with an expected life greater than ten years.

Notable improvements are provided by a new amplifier and oscillator design. Specifically, size and power consumption are reduced and % modulation capability is greatly increased.
