Abstract :
The powering of human implants via inductive coupling has been an object of interest for the past two decades. This paper discusses some of the issues concerning a distant energy link used for supplying artificial human implants, operating at the frequency of 13.56 MHz. A procedure for the design of an energy-receiving coil is given for general applications. A design procedure is also developed, with focus on coils used for supplying human implants. The correctness of the analysis of this later design procedure has been verified by experimental results. Measurements with a human tissue simulant also show little deviation from the predictions.
