A folded dielectric film element is provided which converts energy. The film element includes at least one dielectric film that is bent into folds and provided with electrodes. The electrodes are arranged in the folds so that different electrodes are placed in successive folds. The strength of an electric field increases in one fold and decreases in a successive fold.

[ I claim:] [1.] Folded dielectric film element for converting energy, comprised of at least one dielectric film bent into folds and provided with electrodes, the electrodes being arranged in the folds, so that different electrodes are placed in successive folds, whereby a strength of an electric field increases in one fold and decreases in a successive fold,wherein the electrodes are arranged in successive folds in the order:a first d.c. voltage electrode, a first a.c. voltage electrode, a second d.c. voltage electrode having a voltage with opposite sign to the first d.c. voltage electrode, and a second a.c. voltage electrode in opposite phase to the first a.c. voltage electrode, wherein the a.c. voltages in the a.c. voltage electrodes are used as control voltages for controlling the field strength in successive folds.
