the actuator has at least one solid state structure (2) whose length varies when a voltage is applied and consisting of a one-piece piezo-material with successive transverse integrally connected layers and strip electrodes (4) separated by the thickness of the piezoelectric layers with applied alternate polarity voltages. The strip electrodes form the cross-sectionally bounded surfaces of the solid state structure. The solid state structure is formed on a carrier plate (8) with comb-shaped inter-digitally engaged connecting electrodes (10,12) for the strip electrodes |
