Zusammenfassung:This disclosure provides systems, methods and apparatus for detecting foreign objects. An apparatus for detecting a presence of an object is provided. The apparatus includes a coil configured to inductively sense a presence of an object based on an electrical characteristic of the coil that varies as a function of a temperature of the object when the object is exposed to an alternating magnetic field. The apparatus further includes a controller configured to detect a change in the electrical characteristic.
