Abstract

An actuator element comprises at least two actuator arms. Each of the at least two actuator arms is fixed to a first mount part at a first end of the actuator arm and to a second mount part at a second end of the actuator arm. The at least two actuator arms are configured to cause moving of the first mount part and the second mount part in respect of each other by application of an electric field to the at least two actuator arms. A lens element may comprise the actuator element and a lens mounted on the first mount part. An electronic device may comprise the actuator element or the lens element.
