THERMAL SENSING POLYMERIC CAPACITOR

摘要

A thermal sensing polymeric device (110) such as a capacitor is fabricated from a layer of a copolymeric material (112) including polyvinylidene fluoride and a fluorinated ethylene. The fluorinated ethylene may be selected from the group including trifluoroethylene and tetrafluoroethylene. The thermal sensing polymeric device may be a capacitor fabricated of polyvinylidene fluoride-trifluoroethylene copolymeric material. In such an application, the capacitor device exhibits a change in capacitance as the temperature to which the device is exposed is changed. Specifically, as the temperature of the polymeric material crosses a threshold transition temperature, a substantial change in its capacitance is observed.
