High power efficiency inductive link with full-duplex data communication

During the past ten years research has progressed on the biomedical implantable electronic devices that require power and data communication through an inductive link. In this paper, we describe a novel topology of the inductive link which realizes a full-duplex bi-direction data transmission with only one carrier. Due to this feature, the system power efficiency can be improved significantly through introducing a power control feedback loop. It also improves the controllability and observability of the implant system via the inductive link.
