Abstract

Abstract: Wireless powering allows the implementation of active implanted medical devices (AIMD) without batteries being inserted. The power is commonly transferred by an inductive link, which exhibits a strong relation between efficiency and coil configuration. For example, the electro-magnetic coupling and consequently the transferable power rapidly decreases when the distance is larger than the biggest coil radius. To overcome this obstacle, we investigate an array of multiple equal small-sized electro-magnetic resonators, which not only provides wireless power to a distant position with higher efficiencies, but also allows reducing the dimensions of the terminal coils.
