  • Patent number: 10355624
    Abstract: An electrostatic clutch is described comprising a plurality of micron-scale thickness electrodes, adjacent electrodes being separated by a thin film of dielectric material. A power source and controller apply a voltage across two electrodes, causing an electrostatic force to develop. When engaged, a force can be transferred through the clutch. A tensioning device maintains the alignment of the clutch when the electrodes are disengaged, but permits movement in at least one direction. In some embodiments, multiple clutches are connected to an output to provide variable force control and a broad range of torque input and output values. Moreover, the clutch can be used as an energy-recycling actuator that captures mechanical energy from negative work movements, and returns energy during positive work movements.

  • Patent number: 8531848
    Abstract: A first insulated planar metallic surface is formed under a surface of a substrate which is orientated a first way to an edge of the substrate. A Faraday shield is formed when a second insulated planar metallic surface is juxtaposed to and segregates the first insulated planar metallic surface from the remained of the substrate. The first way can be parallel or perpendicular forming either an edge or surface Coulomb island, respectively. Both planar surfaces can be charged either by mechanical contact or induced charging, Fowler-Nordheim and ion implantation. A Coulomb force is generated between two charged Coulomb islands each located on a different substrate. In addition, these Coulomb islands can also be used as capacitors to transfer signals between the substrates. The Faraday shield can be used to increase the Coulomb force while the potential applied to the shield can alter the Coulomb force.

  • Patent number: 8488294
    Abstract: An electrohydrodynamic fluid accelerator apparatus includes a corona electrode having an axial shape and configured to receive a first voltage. The electrohydrodynamic fluid accelerator apparatus includes a collector electrode disposed coaxially around the at least one corona electrode and configured to receive a second voltage. Application of the first and second voltages on the corona electrode and the collector electrode, respectively, causes fluid proximate to the corona electrode to ionize and travel in a first direction between the corona electrode and the collector electrode, thereby causing other fluid molecules to travel in a second direction to generate a fluid stream. In at least one embodiment of the invention, the ionized fluid proximate to the emitter electrode travels in a radial direction from the corona electrode to the collector electrode, causing the other fluid molecules to travel in an axial direction to thereby generate the fluid stream.
