Abstract

An actuator in the form of a stack is described, wherein the stack includes multiple first pairs of layers of a polarized electromechanical material and multiple second pairs of layers of a polarized electromechanical material, and the first and second pairs of layers are disposed, one behind the other, wherein at each pair of layers on each of its terminal surfaces electrically conductive layers are disposed, and, between the layers of each pair of layers, an electrically conductive layer for connection to at least one connection electrode of a second polarity is disposed, and the polarization directions of the electromechanical material of the layers of each pair are aligned opposite to one another, and the directions of polarization of the material of the layers of each pair of layers are aligned perpendicular to the directions of polarization of the material of the layers of each adjacent pair of layers.
