An actuator ( 100 ) taking advantage of ponderomotive forces to enhance its electromechanical performance as a function of input energy. An actuator ( 100 ) may include a first conductive layer ( 102 ) residing on a first electret layer ( 101 ). The actuator ( 100 ) may further include a moveable second electret layer ( 103 ) which is spaced apart in relation to the first conductive layer ( 102 ) when the second electret layer ( 103 ) is in a quiescent state. The actuator ( 100 ) may further include a second conductive layer ( 104 ) in a spaced apart relation to the second electret layer ( 103 ) when the second electret layer (103) is in the quiescent state. The actuator ( 100 ) may further include a voltage source ( 105 ) configured to selectively apply a voltage between the first ( 102 ) and second ( 104 ) conductive layers thereby propelling the second electret layer ( 103 ) to either the first ( 102 ) or second ( 104 ) conductive layer.
