Abstract
A wireless power transfer system is provided. The wireless power transfer system comprises a resonator comprising a capacitor. The capacitor comprises at least two active electrodes; and a passive electrode adjacent the active electrodes and configured to encompass the active electrodes to at least partially eliminate environmental influences affecting the active electrodes and to increase the overall capacitance of the system. The resonator further comprises at least one inductive coil electrically connected to the active electrodes, wherein the resonator is configured to extract power from a generated electric field via resonant electric field coupling.
