A Transcutaneous Energy Transformer for A Non Invasive Rechargeable Cardiac Pacemaker Battery

The improvement method of a flat secondary transcutaneous transformer for a resonant converter that transfers several W of power across a large variable human skin gap is presented and built The converter can power a novel cardiac pacemaker battery through intact skin by using a transcutaneous transformer with an air gap, which is 10 mm The secondary transformer is piled and the coupling coefficient and the conversion efficiency are measured with an experimental set up Coupling coefficient and conversion efficiency is increased compared with conventional transformer.
