Abstract:
A piezoelectric element with a multi-layer construction of piezoelectric layers (4) made of piezoceramic that have electrodes (6, 7) disposed between them, wherein the electrodes are contacted transversely on alternating sides by means of external electrodes (8, 9), wherein the individual piezoelectric layers (4) are comprised of a continuous foil (2), which can be folded during manufacture, and are completely or partially provided with the electrically conductive electrodes (6, 7), wherein the external electrodes (8, 9) are comprised of an electrically conductive screen or mesh, and wherein the multi-layer construction of the piezoelectric layers (4) is provided with an electrically insulating ceramic place (10, 11) at respective ends of the folded layers.
