Abstract
Systems and methods for dynamic coil area and power adjustment based on device position and sensor fusion feedback from touch, optical, Bluetooth, and specific absorption rate sensor devices may include a charging device that may include a first induction coil having an active length and a processor. The charging device may transmit power wirelessly to a portable device having a second induction coil by coupling the first induction coil and the second induction coil. The charging device may determine an adjusted active length of the first induction coil that may be based on a first charging efficiency of the first induction coil. The processor may electronically switch the active length of the first induction coil to the determined adjusted active length. The processor may transmit the power wirelessly to the portable device to charge a first battery of the portable device.
