Claim Text:
1. A heatable surface element, comprising: an insulating substrate; a layer of conductive ink on the substrate, wherein: a layer of positive temperature coefficient (PTC) conductive ink on the substrate and the first portion of the layer of conductive ink in electrical communication therewith to bridge the gaps between the heater conductive paths of the open heater circuit pattern; the capacitive sensor electrode being spaced from and electrically isolated from the layer of PIG conductive ink on the first portion of the layer of conductive ink by the peripheral isolation region; and at least one insulating sealing layer; wherein the first and second portions of the layer of conductive ink and the layer of PTC conductive ink are disposed between the substrate and the at least one sealing layer.
