Abstract
A layered heater is provided that includes a sensor layer formed by a layered process having a plurality of independently controllable zones, and a resistive heating layer disposed adjacent the sensor layer. In one form, the sensor layer is formed of a material having a relatively high temperature coefficient of resistance (TCR) and the resistive heating layer is formed of a material having a relatively low TCR.
