Also known as “magnetic resonance,” WiTricity® technology is often contrasted to “magnetic induction” for its ability to efficiently transfer power over a range of distances and with positional and orientational offsets. A WiTricity-enabled system encompasses power sources and capture devices that incorporate specially designed magnetic resonators which efficiently transfer power over distance via the magnetic near-field. These proprietary source and device designs, and the electronic systems that control them, support efficient energy transfer over distances that are many times the size of the sources/devices themselves.
