    Abstract: A unilateral in-plane thermal buckle-beam microelectrical mechanical actuator is formed on a planar substrate of semiconductor material, for example. The actuator includes first and second anchors secured to the substrate and a floating shuttle positioned movably parallel to the substrate. Symmetric first and second sets of elongated thermal half-beams are secured between the floating shuttle and the respective first and second anchors. The first and second anchors and the first and second sets of thermal half-beams are positioned along one side of the floating shuttle. The half-beams are formed of semiconductor material, such as polysilicon. A current source directs electrical current through the thermal half beams via the anchors to impart thermal expansion of the thermal half-beams and hence linear motion of the floating center beam generally parallel to the substrate. A floating cold beam connected between the shuttle and the substrate constrains and amplifies the motion of the shuttle in a predefined direction.

    Abstract: The mirror device has a mirror 2, and a supporting mechanism which elastically supports the mirror 2 on a substrate 1 in a state in which the mirror floats from the substrate 1, so that the mirror can be inclined in an arbitrary direction. The supporting mechanism has three supporting parts 3A, 3B and 3C that mechanically connect the substrate 1 and mirror 2. Each of the supporting parts 3A, 3B and 3C has one or more plate spring parts 5 that are constructed from a thin film consisting of one or more layers. One end portion of each plate spring part 5 is connected to the substrate 1 via a leg part 9 which has a rising part that rises from the substrate 1. The other end portion of the plate spring part 5 is mechanically connected to the mirror 2 via a connecting part which has a rising part that rises from this other end portion. The mirror 2 is supported on the substrate 1 only via the plate spring part 5 of the respective 3A, 3B and 3C. As a result, compactness and mass production characteristics can be greatly improved while maintaining superior optical characteristics.

    Abstract: A bimorph structure is produced by depositing a first material on a first surface of a first substrate to form a first element structure. A second material is deposited onto a surface of a second substrate to form a second element structure. Electrodes are deposited on a surface of each of the first element structure and the second element structure. The first element structure is bonded to a first transfer substrate, and the second element structure is bonded to a second transfer substrate. The first substrate is removed from the first element structure, and the second substrate is removed from the second element structure. Second side electrodes are deposited on a second surface of each of the first element structures and the second element structure. The first element structure and the second element structure are directly bonded to each other. One of the first transfer substrate and the second transfer substrate is then removed, and the surface of the element structure from which one of the transfer substrates has been removed is bonded to a final target substrate. Thereafter, the other transfer substrate is removed, and electrical connections are made.

    Abstract: A system and method of adjusting the power off positioning of a microactuator is disclosed. The microactuator has a first power off position and comprises a bimorph component. The bimorph comprises at least two materials, wherein the materials have different thermal expansion characteristics. When heated, the bimorph component of the microactuator bends due to asymmetric thermal expansion of the materials. If one of said materials is forced beyond a yield point, then when cooled, the actuator assumes a second power off position. The microactuator maintains the second power off position due to stress in the bimorph, which is induced by forcing the material beyond its yield point.

    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.
