Abstract

An actuator can include one or more shape memory material members and an electrostatic clutch. When an activation input is provided to the one or more shape memory material members, the one or more shape memory material members contract, which causes the actuator to morph into an activated configuration. A height of the actuator increases in the activated configuration. The electrostatic clutch can be configured to maintain the actuator in the activated configuration when the activation input to the one or more shape memory material members is discontinued. One or more processors can be operatively connected to selectively and independently activate the one or more shape memory material members and the electrostatic clutch.
