Abstract
A piezoelectric element has a first and a second stack containing a plurality of piezoelectric ceramic layers and has an intermediate layer disposed between the first and the second stacks. The intermediate layer is formed as a supporting body made of a fiber composite material or glass. Such a multimorphous piezoelectric element exhibits a high efficiency and a high mechanical stability and, in addition, can be operated with low voltages.
