Abstract

Abstract: A compact wireless power and communication development system for implantable devices was designed and tested with two receiver circuits based on a 433 MHz separate RF link and near-field communication link using the power transfer field. Operating ranges were 9 and 6 cm respectively. The power transmitter was designed around a Royer oscillator with the possibility of power control and frequency control using a unique Schottky varactor method allowing 560 kHz frequency shift.
