Abstract
An electromechanical actuator includes a primary electrode, a secondary electrode overlying at least a portion of the primary electrode, and an electroactive layer disposed between the primary electrode and the secondary electrode, where the electroactive layer has a first curvature when zero voltage is applied between the primary electrode and the secondary electrode, and a second curvature when a non-zero voltage is applied between the primary electrode and the secondary electrode.
