Patent ID: 8511175

Claim:
A method for producing a connection component, the method comprising: providing a connection component having an integrated ultrasound sensor, the integrated ultrasound sensor configured to analyze a mechanical stress distribution or configured to determine a prestress force of the connection component, and the ultrasound sensor having an at least two-layered layer structure comprising an electrode layer and, at least one layer of a material having piezoelectric properties, wherein the electrode layer and the layer of a material having piezoelectric properties are vapor deposited or sputtered on at least one freely accessible end of the connection component; and laser-ablating structures for at least one, electrode of an arbitrary shape on a least one end side of the connection component, wherein laser ablation of the structures, in order to form the electrodes with an arbitrary shape, is carried out so that after erosion of a metal layer an underlying layer of a material having piezoelectric properties or the protective layer is damaged minimally or not at all by an intensity of the laser radiation.
