Abstract
Wireless energy transfer methods and designs for implantable electronics and devices include, in at least one aspect, a source resonator external to a patient, a device resonator coupled to an implantable device and being internal to the patient, a temperature sensor, and a tunable component coupled to the device resonator, wherein the tunable component is adjusted to detune a resonant frequency in response to measurement from the temperature sensor, and wherein a strength of the oscillating magnetic fields generated by the source resonator is adjusted to increase power output to maintain a level of power captured by the device resonator, thereby compensating for reduced efficiency resulting from detuning of the device resonator via the tunable component.
