Patent number: 7679080Abstract: A functional molecular device displaying its functions under the action of an electrical field is provided. A Louis base molecule, exhibiting positive dielectric constant anisotropy or exhibiting dipole moment along the long-axis direction of the Louis base molecule, is arrayed in the form of a pendant on an electrically conductive linear or film-shaped principal-axis molecule of a conjugated system, via a metal ion capable of acting as a Louis acid. The resulting structure is changed in conformation on application of an electrical field to exhibit its function. The electrically conductive linear or film-shaped principal-axis molecule and the Louis base molecule form a complex with the metal ion. On application of the electrical field, the Louis base molecule performs a swinging movement or a seesaw movement to switch the electrical conductivity of the principal-axis molecule.Type: GrantFiled: June 23, 2005Date of Patent: March 16, 2010Assignees: Sony Corporation, Sony Deutschland G.m.b.H.Inventors: Eriko Matsui, Nobuyuki Matsuzawa, Akio Yasuda, Oliver Harnack

Patent number: 7582992Abstract: Electromechanical systems utilizing suspended conducting nanometer-scale beams are provided and may be used in applications, such as, motors, generators, pumps, fans, compressors, propulsion systems, transmitters, receivers, heat engines, heat pumps, magnetic field sensors, kinetic energy storage devices and accelerometers. Such nanometer-scale beams may be provided as, for example, single molecules, single crystal filaments, or nanotubes. When suspended by both ends, these nanometer-scale beams may be caused to rotate about their line of suspension, similar to the motion of a jumprope (or a rotating whip), via electromagnetic or electrostatic forces. This motion may be used, for example, to accelerate molecules of a working substance in a preferred direction, generate electricity from the motion of a working substance molecules, or generate electromagnetic signals. Means of transmitting and controlling currents through these beams are also described.Type: GrantFiled: February 9, 2007Date of Patent: September 1, 2009Assignee: CJP IP Holdings, Ltd.Inventors: Joseph F. Pinkerton, John C. Harlan

Patent number: 7456482Abstract: An improved microelectromechanical switch assembly comprises a linearly movable switch rod constrained via a switch bearing, the switch rod being actuated by electrostatic deflection. Movement of the switch rod to one end of its travel puts the switch assembly in a closed state while movement of the switch rod to the other end of its travel puts the switch assembly in an open state. In an embodiment of the invention, one or both of the switch rod and the switch bearing are fabricated of a carbon nanotube. The improved microelectromechanical switch assembly provides low insertion loss and long lifetime in an embodiment of the invention.Type: GrantFiled: March 18, 2005Date of Patent: November 25, 2008Assignee: Cabot Microelectronics CorporationInventors: Heinz H. Busta, Ian W. Wylie, Gary W. Snider

Patent number: 7408184Abstract: A functional molecular element whose functions can be controlled by an electric field based on a new principle. A Lewis base molecule (14) with positive permittivity anisotropy or a dipole moment in the major axis direction of the molecule is disposed, via a metal ion (3) that can act as a Lewis acid, in a pendant-like form on a key molecule (2) in the form of a line or film that has a conjugated system and exhibits conductivity, thereby forming a functional molecular element 1 that can realize a function where the conformation changes due to the application of an electric field. The conductive key molecule (2) and the Lewis base molecule (14) form a complex with the metal ion (3). When an electric field is applied in a direction perpendicular to the plane of the paper in FIG. 1(b), for example, the Lewis base molecule (14) performs a 90° “neck twisting” movement with the up-down direction in the drawing as the axis.Type: GrantFiled: December 25, 2003Date of Patent: August 5, 2008Assignee: Sony CorporationInventors: Eriko Matsui, Oliver Harnack, Nobuyuki Matsuzawa, Akio Yasuda
