Abstract

This paper presents a resonant inductive link for power and data transfer to a pulse generator implanted in the chest. The proposed link consists of two planar resonators and has been optimized for operating in the MedRadio band centered at 403 MHz. The wireless power/data link occurs between an external resonator operating in direct contact with the skin and a receiving resonator integrated in the silicone header of a pulse generator implanted in the chest. Numerical and experimental results are presented and discussed. From measurements performed by using minced pork to simulate the presence of human tissues, an efficiency of about 51% is demonstrated. The feasibility of using the proposed link for recharging the battery of the medical device in compliance with safety regulations is also verified and discussed.
