Abstract
Techniques for proximity sensing in a wireless power transmitter in a system, method, and apparatus are described herein. For example, an apparatus may include a transmitter coil configured to generate a magnetic field. The apparatus may also include a controller configured to reduce a strength of the magnetic field based on a proximity detection of an object.
