    Abstract: Le dispositif comporte un premier plot d'actionnement (5) en matériau électriquement conducteur avec une première surface de contact. Un second plot d'actionnement (6) en matériau électriquement conducteur fait face au premier plot d'actionnement (5). Un circuit d'actionnement (7) électrostatique déplacent les plots d'actionnement (5, 6) l'un par rapport à l'autre entre une première position et une autre position. Le circuit d'actionnement (7) comporte un dispositif d'application d'un potentiel plus important sur le second plot d'actionnement (6) que sur le premier plot d'actionnement (5). Un film (8) en matériau électriquement isolant réalise l'isolation électrique entre les premier (5) et second (6) plots. Le film (8) en matériau électriquement isolant comporte une interface avec une source (11) en ions positifs et est perméable auxdits ions positifs. La source en ions positifs (11) est dépourvue de vapeur d'eau.

    Abstract: 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.

    Abstract: An electrostatic bimorph actuator includes a cantilevered flexible bimorph arm that is secured and insulated at one end to a planar substrate. In an electrostatically activated state the bimorph arm is generally parallel to the planar substrate. In a relaxed state, residual stress in the bimorph arm causes its free end to extend out-of-plane from the planar substrate. The actuator includes a substrate electrode that is secured to and insulated from the substrate and positioned under and in alignment with the bimorph arm. An electrical potential difference applied between the bimorph arm and the substrate electrode imparts electrostatic attraction between the bimorph arm and the substrate electrode to activate the actuator. As an exemplary application in which such actuators could be used, a microelectrical mechanical optical display system is described.
