Wireless power transfer system applied to an active implantable medical device

This study deals with the design of a Wireless Power Transfer (WPT) system based on magnetic resonant coupling between two coils, whose secondary is located inside the human body and connected to a battery recharge system of an active implantable medical device (AIMD). A co-simulation tool is developed using circuit and electromagnetic field models to simulate the WPT system. Simulation results are obtained for different positions of the secondary coil and are compared with experiments.
