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;
a ferrite housing disposed around the internal housing, the ferrite housing configured to reduce an amount of magnetic flux that reaches the internal housing; and
at least one wire coil wrapped around the ferrite housing and electrically coupled to the controller, the at least one wire coil configured to receive wireless energy from an external power transmitter.

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.
