Patent ID: 6842970

Claim:
A method of producing a strain-sensitive resistor arrangement, comprising the steps of: (a) applying an insulating layer to the first side of the support sheet and applying a resistive layer onto the insulating layer after the insulating layer has been applied to said support sheet, wherein the insulating layer is printed onto the support element in the form of a glass frit, the glass frit is dried, and a conductive paste is applied onto the insulating layer as the resistive layer; (b) matching an area of a flexible film layer to a shape of a recess defined in a surface of a support element; (c) covering the first side of the first support sheet, the insulating layer, and the resistive layer with the flexible film layer such that the flexible film covers the insulating layer and the resistive layer, wherein an adhesion of the flexible film layer to the at least one of the insulating layer and the resistive layer is greater than an adhesion of the first support sheet to the at least one of the insulating layer and the resistive layer; (d) removing the support sheet from the insulating layer and the resistive layer such that at least the resistive layer remains on the flexible film layer and applying the flexible film layer with at least the resistive layer to the surface of the support element so that the area of the flexible film layer matching the shape of the recess defined in the surface is congruent with the shape of the recess defined in the surface; and (e) subjecting the support element to a heat treatment after said step (d) to burn off the flexible film layer and sinter on the at least one of the insulating layer and the resistive layer.
