Harmonics-based bio-implantable telemetry system.

Miniaturization is a key focus for medically implantable electronics such as Cochlear and Retinal prosthesis, and medical monitoring and recording applications. The need for low power dissipation is equally important, and power-hungry crystals and oscillators are commonly used to produce and control the implant's carrier transmission frequency. This paper presents a new harmonics-based method that allows this transmission frequency to be varied and controlled externally, while also minimizing the size and power requirements of certain implanted devices.
