Zusammenfassung:A layered heater is provided that comprises at least one resistive layer defininga circuit configuration, the circuit configuration comprising at least oneresistive trace oriented relative to a heating target and comprising a materialhaving temperature coefficient characteristics such that the resistive traceprovides power commensurate with demands of the heating target. In one form,resistive traces of the resistive layer are a PTC material having a relativelyhigh TCR and are oriented approximately perpendicular to a primary heating direction.In another form, resistive traces of the resistive layer are an NTC material havinga relatively high BETA coefficient and are oriented approximately parallelto a primary heating direction. Se proporciona un calentador estratificado que comprende por lo menos una capa resistiva que define por lo menos una configuracion de circuito, la configuracion de circuito comprende por lo menos un trazo resistivo orientado con relacion a un objetivo de calefaccion y que comprende un material que tiene caracteristicas de coeficiente de temperatura de tal forma que el trazo resistivo proporciona energia en proporcion con las demandas del objetivo de calefaccion. En una forma, los trazos resistivos de la capa resistiva son un material de PTC que tiene una TCR relativamente elevada y se orientan aproximadamente en perpendicular a una direccion de calefaccion primaria. En otra forma, los trazos resistivos de la cpa resistiva son un material de NTC que tiene un coeficiente BETA relativamente elevado y se orientan aproximadamente en paralelo a una direccion primaria de calefaccion.
