1. A heating device for producing heat when connected to an electrical power source, comprising:
- an electrically insulative substrate positioned beneath a flexible member;
a plurality of apertures through said substrate and said member, at least some of said apertures being narrow elongated apertures;
a conductive layer on said substrate in a pattern thereby forming a buss structure including first and second busses along opposite sides of said substrate, and alternating traces electrically connected to opposite said busses and extending between said busses, said traces surrounding said apertures, wherein said substrate is adapted to limit elongation of said conductive layer when said substrate is subjected to a flexing action, so as to improve durability of the conductive layer; and
a resistive layer applied to said conductive layer such that when an electrical power source is connected to said buss structure of the heating device, heat is generated.

Abstract
A heating device includes a conductive layer on an electrically insulated substrate. The substrate and conductive layer have a plurality of cross-like apertures therethrough. The conductive layer includes busses and traces extending from the busses, the traces surrounding the apertures. A resistive or thermistor layer is provided over the conductive layer.
