Abstract: A pair of electrostatic nanotweezers (2) is characterized by comprising a plurality of nanotubes extending from their proximal ends at which they are fixed to a holder (6), coating films with which the surfaces of these nanotubes are insulation coated, and two lead wires (10, 10) connected to two (8, 9) of these nanotubes, wherein a voltage is applied across the lead wires to produce an electrostatic attractive force by which the front ends of the two nanotubes are made openable and closable, thereby gripping a nanosubstance therebetween. Further, if a piezoelectric film (32) is formed on the surface of each nanotube (9) and caused to stretch and contract so as to make the front ends of the nanotubes openable and closable, then any nanosubstance, whether dielectric, semiconductor or conductor, can be handled. Further, if three nanotubes are made openable and closable by the electrostatic system, nanosubstances of any desired shape, such as spherical or linear, can be handled. Further, gripping, moving and discharging of nanosubstances are facilitated by constituting a nanomanipulator in combination with a three-dimensional driving mechanism.

Abstract: A MEMS (Micro Electro Mechanical System) electrostatic device operated with lower and more predictable operating voltages is provided. An electrostatic actuator, an electrostatic attenuator of electromagnetic radiation, and a method for attenuating electromagnetic radiation are provided. Improved operating voltage characteristics are achieved by defining a non increasing air gap between the substrate electrode and flexible composite electrode within the electrostatic device. A medial portion of a multilayer flexible composite overlying the electromechanical substrate is held in position regardless of the application of electrostatic force, thereby sustaining the defined air gap. The air gap is relatively constant in separation from the underlying microelectronic surface when the medial portion is cantilevered in one embodiment. A further embodiment provides an air gap that decreases to zero when the medial portion approaches and contacts the underlying microelectronic surface. A moveable distal portion of the flexible composite is biased to curl naturally due to differences in thermal coefficients of expansion between the component layers. In response to electrostatic forces, the distal portion moves and thereby alters the distance separating the flexible composite from the underlaying microelectronic surface. Structures and techniques for controlling bias in the medial portion and the resulting air gap are provided. The electrostatic device may be disposed to selectively clear or intercept the path of electromagnetic radiation. Materials used in the attenuator can be selected to pass, reflect, or absorb various types of electromagnetic radiation. A plurality of electromagnetic attenuators may be disposed in an array and selectively activated in subsets.

Abstract: An actuator element of a MEMS device on a substrate able to create large, out-of-plane deflection includes two separated metallic layers contacting the substrate. The second metallic layer has a first portion contacting the substrate and a second portion having cantilevered over the substrate and first metallic layer. A first insulating layer contacts the cantilevered metallic layer on a bottom contacting surface and a second insulating layer contacting the cantilevered metallic layer on a portion of a top contacting surface. The second, cantilevered portion of the metallic layer is prestressed causing the distal end to deform away from the substrate. Applying a voltage potential between the first and second metallic layers creates an electrostatic field drawing the distal end toward the substrate.

Abstract: A micro-electro-mechanical actuator device includes a fixed structure and a mobile structure. The mobile structure includes a first deformable band, a second deformable band, and a third deformable band, both of which extend on opposite sides of the first deformable band, each of which carries a piezoelectric actuator. In a working condition, in which the second and third piezoelectrics are biased, the second and third deformable bands are subjected to a negative bending, while the first deformable band is subjected to a positive bending. There are thus generated two translations that add together, causing a displacement of the first deformable band greater than the one that may be obtained by a single membrane of an equal base area.

Abstract: A pop-up laminate structure includes rigid layers, at least one flexible layer, at least one optical component, and an actuator. At least one of the rigid layers defines gaps extending there through to form a plurality of rigid segments separated by the gaps in the rigid layer. The flexible layer is bonded to the rigid segments to form joints for folding. The optical component is mounted to a rigid layer and configured to generate, capture or alter a light beam. The actuator is mounted to at least one of the rigid layers and configured to displace at least one rigid segment that, in turn, displaces the optical component. At least some of the layers are bonded to adjacent layers only at selected locations forming islands of inter-layer bonds to allow expansion of the laminate into an expanded three-dimensional structure.
