Title: METHOD FOR PRODUCING AN ELECTROMECHANICAL TRANSDUCER
Abstract:
The present invention relates to a method for producing an electromechanical, for example piezoelectric, transducer in which a first polymer layer (2; 2a) comprising cutouts (3; 3a) is applied to a first continuous polymer layer (1; 1a) by means of a printing and/or coating method, a cover (4; 1b, 2b) is applied to the first polymer layer (2; 2a) comprising cutouts (3; 3a) in such a way that the cutouts (3; 3a) of the first polymer layer (2; 2a) comprising cutouts (3; 3a) are closed off with the formation of cavities (5), and the cover (4;1b, 2b) is connected to the first polymer layer (2; 2a) comprising cutouts (3; 3a). The invention furthermore relates to electromechanical transducers producible by a method according to the invention, and the use of said electromechanical transducers.
