Abstract:

A novel heater is disclosed for a temperature sensitive actuator. The heater is a polymeric positive temperature coefficient (PPTC) device consisting of conductive filler and semi-crystalline polymer. The PPTC heater is strategically designed to have a predetermined self-regulation temperature suited to whatever application utilizes the heater. Physical characteristics of the PPTC heater, such as gap width and thickness, enable the current flow through the heater to be strategically controlled.
