Abstract: A set of shielded coils for wireless power transmission into a medical implant is described in which the external, power transmission coil is blocked at least on one side by a shield with a broken ring and radial fingers while the power receiver coil inside the medical implant is surrounded by a shield having a broken ring connecting radial fingers and ribs around its circumference.

A ground plane of the implant's internal circuitry, which is within the shield along with the receiver coil, can cap off the cupped receiver shield to form a Faraday cage with it. The metal or other conductive shielding prevents large electric fields from the coils from penetrating into the tissue of the subject while simultaneously allowing magnetic fields inductively couple the coils for charging.
