Abstract
Transcutaneous signal and power transmission to implants is possible via an RF-link. Such an RF-link should have a high power transfer efficiency. The influence of variations in spacing and lateral displacement of the two coils should be minimized. This is necessary if no internal regulation is provided or an AM-signal is transmitted. For this purpose, a transcutaneous signal transmission system has been developed with over-critical coupled coils and an efficiency of 90 percent. The received power amplitude is kept within narrow limits despite of placement variations. This was achieved with stagger tuned coils, where the transmitter frequency is somewhat detuned out of center frequency of the first resonant circuit.This publication has 1 reference indexed in Scilit:
