Wireless power transfer link for rechargeable deep brain stimulators

This paper proposes a novel wireless link for energizing pulse generators for deep brain stimulation. The proposed link consists of two magnetically coupled planar resonators. Experimental results referring to a prototype working in the MedRadio band and using minced pork in order to take into account the presence of human tissues are reported and discussed. Results obtained this way demonstrate a transfer efficiency of about 10.62 %. The compliance with safety regulations is also verified by means of full-wave simulations.
