Wireless Charging Solution for Artificial Cardiac Pacemakers

Abstract In order to surpass the energy supply limit and its drawbacks, the idea of wireless charging for artificial cardiac pacemaker is discussed. Since there are many ways of delivering power wirelessly with various advantages and disadvantages, only one will be considered because it is best suited for medium frequency devices that need quick and efficient charging, while being completely harmless to humans. The wireless power transfer (WPT) technique investigated in this paper is the inductive coupling. This technique is based on coupling two main coils (inductors); one that transmits power generated in a first circuit, and another that receives it and delivers it to the pacemaker through a second circuit. Throughout this paper, the aim is to find the optimum way to charge the pacemaker wirelessly and at the same time minimize its size by reducing the battery design criteria. Keywords: energy supply, inductive coupling, pacemaker, wireless power transfer.
