A self-standing sandwich structure includes at least one capacitive sensor member and/or at least one heater member for automotive vehicle application. The self-standing sandwich structure includes an upper protective layer that is attached, for manufacturing and storage purposes, to a carrier film member of sufficiently low surface energy for enabling separating the carrier film member and the upper protective layer in a non-destructive manner, a lower protective layer, a bottom adhesive layer that is attached to the lower protective layer, and at least an upper electrically conductive layer arranged between the upper protective layer and the lower protective layer.

Foil-based PTC heaters are self-regulating, i.e. do not need any electronic control unit (ECU) to limit the maximum heating current. In order to establish different heating power levels the present invention proposes to choose different PTC ratio/onset characteristics. In addition, the print design of the PTC ink can be adjusted accordingly.
