Abstract :
Wireless power transfer for biomedical implants using capacitive coupling (electric near field coupling) has been presented in this work as an attractive alternative to the traditional inductive coupling method with the benefits of simple topology, fewer components on the implant side, better EMI performance and robustness to surrounding metallic elements. The analysis and design of capacitive coupled power link for biomedical implants is presented with emphasis on modeling tissue losses. Design and evaluation of capacitive power link has been presented with experimental results that are verified using the theoretical model developed.
