Abstract(s)Power delivery from an external source to implanted devices through wireless links is hindered by SAR regulations, which limit the amount of power radiated by an external source that reaches an implant. In order to increase the power delivered to the implant, we studied a solution with two transmitters and compared results with the common single transmitter link. HFSS and COMSOL have been used to show that a power increase of around 40% inside a human head model was achieved while respecting SAR limits and keeping tissue temperature under control, stabilizing at around 37.4 degrees C.
