Abstract
A structure for polymeric thermistor device and method of making the same are disclosed. The polymeric thermistor makes use of a polymeric composite filled with conductive filler and show resistance variations at different temperatures. A polymeric substrate filled with conductive filler is cross-linked so that the whole polymeric composite structure filled with conductive filler is able to memorize shape. Then, the cross-linked polymeric composite undergoes a simple-sheared process and turns into a polymeric composite with a strain more than 1%. Therefore, the micro-structure and electrical properties of the conductive filler are changed.
