Abstract
The present invention relates to a method for producing an electromechanical, for example piezoelectric, transducer in which a first polymer layer comprising cutouts is applied to a first continuous polymer layer by means of a printing and/or coating method, a cover is applied to the first polymer layer comprising cutouts in such a way that the cutouts of the first polymer layer comprising cutouts are closed off with the formation of cavities, and the cover is connected to the first polymer layer comprising cutouts. The invention also relates to electromechanical transducers produced by the method according to the invention, and the use of said electromechanical transducers.
