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.
