1. A layered heater comprising:

  • a substrate;

    a resistive layer formed on the substrate, the resistive layer comprising a resistive circuit pattern, the resistive circuit pattern defining a trace having a length, a thickness, and a spacing; and

    a protective layer formed on the resistive layer, wherein the thickness of the resistive circuit pattern varies along the length of the trace of the resistive circuit pattern for a variable watt density.
