摘要
Disclosed herein are systems and methods for wirelessly transmitting power to receivers that are freely mobile, such as power receivers for sensors attached to animal experiments. An example transmitter includes a resonator including a generator and transmitter coil, an initial drive signal generator that removes the generator from an ‘off’ state thereby causing the transmitter coil to create an alternating magnetic field that oscillates within a threshold of a resonant frequency of the generator, a phase detector that receives a signal from a receiver coil receiving power via the magnetic field, and a transition module that switches from the initial drive signal to a drive signal generated based on output from the phase detector. An example wireless power receiver has three turns of wire, one on each axis, around a ferrite plate, the outputs of which are connected in parallel to produce a combined output power signal.
