<p>Disclosed is a multilayered actuator provided with a stack (31) of thin insulating layers (20) made of a piezoactive material, wherein incorporated inner electrodes (21,22) alternatingly leading out of said stack (31) are electrically connected in parallel via outer electrodes (23,24) which are respectively associated with one side of the stack (31). At least one of the outer electrodes (23, 24) has a conducting layer (15) and an interwoven structure (5) which is connected to the conducting layer (15) in certain places, whereby said interwoven structure is embodied in such a way and connected to the conducting layer (15) in such a way that forces arising during the operation of the multilayered actuator in the region of the outer electrodes (23,24) as a result of a longitudinal contraction/longitudinal dilation of the stack (31) can be at least substantially compensated inside said interwoven structure (5). The interwoven structure especially comprises weft threads (10) and warp threads (11) which form lozenged gaps or meshes (12) with an inner angle (16) which is adapted to the piezoactive material</p> |
