THERMAL SENSING WIRE AND TECHNIQUES FOR THERMAL SENSING

Abstract:

A thermal sensor wire. The thermal sensor wire may include a thermal sensing portion extending along a wire axis of the thermal sensor wire; and a carrier portion, the carrier portion extending along the wire axis, adjacent to the thermal sensing portion, the thermal sensing portion comprising a polymer positive temperature coefficient (PPTC) material or a negative temperature coefficient (NTC) material.
