A heating element converts electrical energy into heat through the process of resistance, otherwise known as Joule heating. A flexible PTC heater made of conductive rubber Resistive heaters can be made of conducting PTC rubber materials where the resistivity increases exponentially with increasing temperature. TAG: This way it conducts electricity better when the temperatures in its surroundings are low. Ceramic-based non-linear PTC resistors (used, among other things, as a self-regulating heating element in the ceramic heater) Polymer-based non-linear resistors (used, for example, as self-resetting overcurrent protection) While all metals have similar properties, these are much more pronounced with a PTC resistor. The total thermal mass of the system is determined by the shape, size, number and distribution of each individual printed heater element.
