Abstract
Described herein are improved configurations for a wireless power transfer. Described are methods and designs for implantable electronics and devices. Wireless energy transfer is utilized to eliminate cords and power cables puncturing the skin to power an implantable device. Repeater resonators are employed to improve the power transfer characteristics between the source and the device resonators.

10. A wireless energy transfer system for powering devices implanted in a patient comprising:
-
a high-Q source resonator having a first resonant frequency, the source resonator being external to the patient, coupled to a power source, and configured to generate oscillating magnetic fields at substantially the first resonant frequency, a high-Q device resonator having a second resonant frequency, the device resonator coupled to an implantable device requiring a supply power, the device resonator being internal to the patient, and configured to capture the oscillating magnetic fields generated by the source resonator, a temperature sensor, positioned to measure the temperature of the device resonator, and a tunable component coupled to the device resonator, wherein the tunable component is adjusted to change the first resonant frequency of the device resonator in response to the reading from the temperature sensor. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
