Abstract
In an embodiment a device includes at least one piezoelectric actuator including a plurality of piezoelectric layers and a first reinforcing element and a second reinforcing element, wherein the piezoelectric actuator is arranged between the reinforcing elements, wherein the piezoelectric actuator is configured to alter its expansion in a first direction when an electrical voltage is applied, and wherein the reinforcing elements are configured to deform on account of a change in an expansion of the piezoelectric actuator such that a central region of the respective reinforcing element is moved relative to the piezoelectric actuator in a second direction, the second direction being perpendicular to the first direction.
