  • Patent number: 8297133
    Abstract: A pressure sensor has a multiplicity of piezoelectric converter elements which are arranged such that they are essentially parallel to a force-applying or pressure-applying direction. The converter elements can be arranged at a distance from one another by an insulating material and/or are at least partially embedded in the material. A support material having greater mechanical rigidity than the converter elements, in particular in the force-applying or pressure-applying direction, is assigned to at least a number of piezoelectric converter elements, or the piezoelectric converter element is applied, in the form of a layer, to a supporting body made from this support material and is electrically contact-connected, for example, by a bottom electrode, which is arranged between the converter element layer and the supporting body, and a cover electrode which is applied to an outer side of the converter element layer.
