How does WiTricity technology compare to traditional magnetic induction, like that used in a charging mat or electric toothbrush?
Traditional magnetic induction requires that the power source and capture device be very close to one another—usually within millimeters—to transfer power efficiently. That’s why many traditional inductive charging solutions require a cradle to hold the capture device, or a mat on which the capture device must rest. WiTricity technology is based on sharply resonant strong coupling, and is able to transfer power efficiently even when the distances between the power source and capture device are several times the size of the devices themselves.
