The invention relates to an electro-switchable polymer film assembly having a first and a second surface side, comprising at least one pair of electrodes () and a polymer matrix (), wherein structuring particles () can be embedded in the polymer matrix and the polymer matrix or the structuring particles consist of an electro-active polymer, wherein furthermore, the first and/or the second surface sides can be transferred from a plane condition into a structured condition by electric switching of the electro-active polymer.

Electro-switchable polymer film assembly and use thereof

The present invention relates to an electromechanical converter, in particular an electromechanical sensor, actuator and/or generator, which comprises a polymer element obtainable from a reaction mixture comprising a polyisocyanate, a polyisocyanate prepolymer and a compound having at least two isocyanate-reactive hydroxy groups. The present invention additionally relates to a process for the production of such an electromechanical converter and to the use of a polymer element according to the invention as an electromechanical element. The present invention relates further to an electronic and/or electrical device comprising an electromechanical converter according to the invention and to the use of an electromechanical converter according to the invention in an electronic and/or electrical device.

Electromagnetic converter with a polymer element based on a mixture of polyisocyanate and isocyanate-functional prepolymer and a compound with at least two isocyanate reactive hydroxyl groups

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.

Process for the producing of an electromechanical transducer

The present invention relates to a ferroelectret multi-layer composite () comprising at least two polymer films arranged one on top of the other and bonded together, wherein voids are formed between the polymer films, said voids being tubular channels, particularly running parallel to one another. The invention further provides a process for the production of a ferroelectret multi-layer composite with parallel tubular channels, and a device for carrying out the process for the production of the ferroelectret multi-layer composite according to the invention. In addition, the invention relates to a piezoelectric element containing a ferroelectret multi-layer composite according to the invention.
