Abstract
A foreign object detection device for a wireless power transfer system for inductive power transfer from a primary part to a secondary part across an airgap, includes a sensor module with a multitude of detection cells. In order detect a foreign object near a detection cell, a stimulation signal is applied to a detection cell by means of a stimulation unit and the time response of the detection cell is measured with a measurement unit and compared to a reference time response of that detection cell that has been previously sensed by a control and signal processing unit.
