Abstract
A medical device-powering wireless receiver for use with a first electromagnetic resonator coupled to a power supply. The wireless receiver including a load is configured to power the medical device using electrical power, and a second electromagnetic resonator adapted to be housed within the medical device and configured to be coupled to the load, wherein the second electromagnetic resonator is configured to be wirelessly coupled to the first electromagnetic resonator to provide resonant, non-radiative wireless power to the second electromagnetic resonator from the first electromagnetic resonator, the area circumscribed by the inductive element of at least one of the electromagnetic resonators can be varied to improve performance.
