Abstract
In some embodiments, an actuator assembly is provided which includes actuators, having a storage material, a volume changing material comprising a metal capable of changing volume in response to species insertion and removal, an ion transport material between the storage material and the volume changing material, and electrodes connected so as to be capable of providing an actuation voltage to the plurality of actuators. The actuators are configured such that the actuator assembly provides substantially anisotropic movement. In some embodiments, the actuator assembly includes actuators arranged in a stacked configuration. In some embodiments, the volume changing material includes spaced apart elongated structures which may be recessed within the storage material.
