1. An implantable TET receiver unit, comprising:
- an internal housing;
an energy source disposed in the internal housing;
a controller disposed in the internal housing, the controller configured to control operation of the TET receiver; and
an external housing disposed around the internal housing, wherein the external housing comprises a plurality of sides comprising at least one small side and at least one large side, wherein the external housing comprises ferrite components that define a ferrite gap therebetween, and wherein the ferrite gap extends along one of the at least one small side and the at least one large side.

Abstract
Systems and methods for wireless energy transfer are described. A transmitter unit has a transmitter resonator with a coil that is coupled to a power supply to wirelessly transmit power to a receiver unit. A receiver unit has a receiver resonator with a coil coupled to a device load. The receiver unit can include a ferrite enclosure to prevent transmission of magnetic flux into electronics of the receiver unit, and can include ferrite fins to increase a coupling between the transmitter resonator and the receiver resonator.
