Abstract
The bending transducer has a layer construction containing a piezoelectrically active element, which is formed of a piezoactive material, in particular a piezoceramic, and electrode layers fitted thereon. In order to enable a high bending loading of the bending transducer and to reduce the risk of fracture, it is provided that a protective layer is applied to the layer construction on the outer side, preferably on both sides, which protective layer is applied to the layer construction in particular under prestress.

19. A bending transducer, comprising:
-
a layer construction containing a piezoelectrically active element formed of a piezoactive material and electrode layers applied on said piezoactive material; contact surfaces; and a protective layer having two films and disposed on an outer side of said layer construction, said layer construction disposed in a manner of a sandwich between said two films forming said protective layer, said two films overlapping on an edge-side over said layer construction and have in each case conductor tracks on an inner side facing said layer construction, via said conductor tracks said piezoelectric element is contacted, and said protective layer having said contact surfaces disposed in an overlapping partial region and on which in a connected state a connection line is contacted. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
