Abstract: 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.

Abstract: An electrical connection encapsulation device for electrically connecting a flexible flat cable to discrete electrical wires. The device includes a flexible flat cable with a dielectric, planar, flexible carrier and at least one electrically conductive line attached to at least one surface, first and second flat, soft and pliable material layers attached to the first surface and the second surface of the flexible carrier, respectively, by adhesive bonds, at least one electrical connector member that is electrically connectable to a discrete electrical wire at one end and to the at least one electrically conductive line with the other end. The first and second layers are arranged to at least partially overlap the at least one electrically conductive line in the connecting end region in the perpendicular direction, and to extend beyond the end of the at least one electrical connector member that is facing away from the connecting end region.

Abstract: A method for producing a foil-based pressure sensor includes the steps of: providing a bottom element with a bottom foil and at least one bottom electrode disposed on the bottom foil; providing a plurality of top elements, each top element having a top foil with at least one top electrode disposed under the top foil, a combined area of the top elements being smaller than an area of the bottom element; and individually positioning and at least indirectly connecting the top elements to the bottom element so that at least one top electrode of each top element is disposed over at least one bottom electrode of the bottom element to form a sensor cell that is adapted to be activated when a pressure on the sensor cell exceeds a turn-on point. The turn-on point is adjusted by selecting a position of a top element from a plurality of positions.

Abstract: 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.

Abstract: A PTF (polymer thick film) device (10) comprises a substrate (22, 32), a functional PTF layer (24,34) applied on the substrate and a protective cover (25, 35) applied over the PTF layer, the protective cover being an adhesive tape comprising a carrier layer (27, 37) and a layer of adhesive (26, 36), the carrier layer being coated with the layer of adhesive (26, 36), the layer of adhesive (26,36) having a thickness comprised in the range from 10% to 100% of the print thickness of the PTF layer (24, 34). The PTF layer is a carbon ink layer, a silver ink layer, a graphite ink layer, a carbon-silver ink layer, a carbon-graphite ink layer, a graphite-silver ink layer, a carbon-graphite-silver ink layer or a PTC layer (Positive Temperature Coefficient). The PTF device can be used as an electric heater, e.g for car seats.

Abstract: A sheet-type ohmic heating element (10) comprises a substrate sheet (12) having applied thereon a layer of PTC material (14) and a protective cover sheet (16) laid over the layer of PTC material. The protective cover sheet extends beyond the boundary of the layer of PTC material and is affixed to the substrate sheet circumferentially around the boundary of the layer of PTC material. The protective cover sheet and the layer of PTC material are arranged in non-adhesive contact with each other.
