Abstract
A multilayer composite includes at least two composites, each composite having a film and an electronically conductive layer. Several composites are laminated to provide an increased conversion between mechanical and electrical energies not only due to the multiplication of the effect of each layer, but also due to the fact that the multilayer structure itself renders the multilayer composite more rigid. In addition, the multilayer structure facilitates application of an electrical field over thinner portions of the structure, thereby requiring much less potential difference between electrodes.

A multilayer composite comprising at least two composites, each composite comprising:
- a film made of a dielectric material and having a front surface and rear surface, the front surface comprising a surface pattern of raised and depressed surface portions, and
- a first electrically conductive layer being deposited onto the surface pattern, the electrically conductive layer having a corrugated shape which is formed by the surface pattern of the film, and
- wherein the composites are arranged so that the rear surface of one composite is facing the front surface of an adjacent composite.
A multilayer composite comprising at least two layers of composite, each composite layer comprising:
- a film made of a dielectric material and having a front surface and rear surface, the front surface comprising a surface pattern of raised and depressed surface portions, and
- a first electrically conductive layer being deposited onto the surface pattern, the electrically conductive layer having a corrugated shape which is formed by the surface pattern of the film, and
- wherein the layers of composite are arranged so that the rear surface of one layer of composite is facing the front surface of an adjacent layer of composite.
