Abstract
A layered heater is provided that includes at least one resistive layer having a resistive circuit pattern, the resistive circuit pattern defining a length, a width, and a thickness, wherein the thickness varies along the length of the resistive circuit pattern and/or the width of the resistive circuit pattern for a variable watt density. The present disclosure also provides layered heaters having a resistive circuit pattern with a variable thickness along with a variable width and/or spacing of the resistive circuit pattern in order to produce a variable watt density.
