In certain aspects, a method and apparatus for detecting foreign objects using heat sensitive material and inductive sensing is disclosed. In certain aspects, a foreign object detection system includes a heat sensing system comprising a heat sensitive material having a property configured to change as a function of temperature. The foreign object detection system further includes an inductive sensing system comprising one or more sense coils, wherein a change in an electrical characteristic of the one or more sense coils is indicative of presence of a foreign object. The foreign object detection system further includes a controller coupled to the heat sensing system and the inductive sensing system, wherein the controller is configured to determine presence of the foreign object based on at least one of a measure of the property of the heat sensitive material or a measure of the electrical characteristic of the one or more sense coils.
