Flexible resonator attachment
First Claim
1. A wireless energy transfer system, comprising:
- a coil comprising at least one loop of electrically conductive material and configured to receive an oscillating electrical current, and to generate an oscillating magnetic field in response to the electrical current; and
a member formed of magnetic material and positioned relative to the coil such that during operation of the system, when a device comprising a magnet is connected to the member, energy is transferred from the coil to the device through the oscillating magnetic field.

Abstract
Described herein are improved configurations for a wireless power transfer for electronic devices. In embodiments reconfigurable or flexible attachment between a source and a device is realized using permanent magnets or electromagnets. Magnetic material may be positioned on or around one or more of the resonator to provide for locations for attaching permanent magnets. A permanent magnet attached to or near one of a source or device or repeater resonators may be used to flexibly attach to the non-lossy magnetic material of another resonator structure. In embodiments, replacing lossy permanent magnets and/or electromagnets in even one of the resonators of a wireless power system may be advantageous to system performance.
