Abstract

Upon heating, the inner conductive pathway inside the conductive polymer composites (CPCs) changes, thus causing the change in electrical resistance. This thermo-electrical dependence of CPCs can be utilized to design CPCs-based temperature sensors. Herein, we systematically reviewed the recent progress on CPCs-based temperature sensors, as well as their mechanisms and applications in different fields. Finally, the question and challenge of CPCs-based temperature sensor are also discussed.
