This paper will describe a wireless power transmission system which has been used during in vivo testing to power a blood pressure sensing implant [1] located inside the abdominal aorta of a 100 kg swine. Wireless power transmission is accomplished using an external power sender which is magnetically coupled to an RF energy harvester block which has been integrated into the medical implant's system package. The power sender is a class E amplifier which drives a wire loop antenna at 4 MHz, and the power receiver uses a ferro-magnetic core in an LC resonant circuit coupled to a Schottky diode charge pump rectifier followed by a DC voltage regulator. © 2012 by Walter de Gruyter.
