On feasibility and optimization of WiTricity technology for implantable medical devices

Abstract

The present accelerated development of microelectronics led to new health care applications that previously could not have been designed and here can be cited the active implanted medical devices - IMD. But their supply implies the existence of a power source, usually a battery whose lifetime is limited and must be changed so it requires repeated incisions. This paper presents an analysis of Transcutaneous Energy Transfer - TET for recharging the batteries from the IMDs based on wireless technology. It is shown that, by using magnetic resonance (WiTricity), namely a variant thereof, the energy and data transmission are not restricted by the position of the patient (receiver) with respect to the source (transmitter).
