Abstract
An improved wireless transmission system for transferring power over a distance. The system includes a transmitter generating a magnetic field and a receiver for inducing a voltage in response to the magnetic field. In some embodiments, the transmitter can include a plurality of transmitter resonators configured to transmit wireless power to the receiver. The transmitter resonators can be disposed on a flexible substrate adapted to conform to a patient. In one embodiment, the polarities of magnetic flux received by the receiver can be measured and communicated to the transmitter, which can adjust polarities of the transmitter resonators to optimize power transfer. Methods of use are also provided.
