Abstract
The disclosure features living object detectors for a wireless energy transfer systems that include a sensor featuring a first conductor positioned adjacent to a first surface of a substrate, a shield featuring a second conductor different from the first conductor, where at least a portion of the second conductor is positioned proximal to the first conductor and adjacent to the first surface of the substrate, a ground reference featuring a third conductor spaced from the substrate and positioned on a side of the substrate opposite to the first surface, and an electrical circuit coupled to the first, second and third conductors and configured so that during operation of the living object detector, the electrical circuit applies a first electrical potential to the first conductor and a second electrical potential to the second conductor, the first and second electrical potentials being approximately similar.
