摘要： Ultrafast square-law detectors amplify electric currents and electromagnetic waves with frequencies on the order of 100 GHz or more. The detectors use injection of spin-polarized electrons from a magnetic film or region into another magnetic film or region through a thin semiconductor control region. A signal current flowing through a conductive nanowire induces a magnetic field causing precession of electron spin injected inside the semiconductor layer and thereby changing the conductivity of the detector. With the magnetizations of the magnetic regions being parallel or antiparallel to each other, the resulting spin injection current includes a term proportional to the square of the signal current so that the detector behaves as a square-law detector. Such square-law detectors are magnetic-semiconductor heterostructures and can operate as a frequency doubler for millimeter electromagnetic waves.

摘要： A gated nanoscale switch operates as a resonant tunneling device. A conductive channel is formed of a pair of conductive molecular wires and a conductive nanoparticle. Each molecular wire is bound, at one end, to the conductive nanoparticle and, at the opposed end, to one of a pair of electrodes. The structure is located upon a dielectric layer that overlies a conductive substrate. The device may be arranged to operate as a switch with the conductive substrate acting as a gate electrode. Alternatively, the device may be employed to measure the electrical (current versus voltage) characteristics of the molecular wires.

摘要： A sensor fabric has a plurality of flakes of a flexoelectric material and electrodes as threads for connecting the flakes together. Each flake has at least one pair of opposite edges connected by two separate electrodes. When the sensor fabric is placed in contact with the surface of an object, the flake is bent along the contour of the object surface. The bending of the flexoelectric flake generates a polarization voltage between its opposite edges, which can be measured via the electrodes to determine the local surface contour of the object.

摘要： Apparatus and systems are provided for data signaling between a centralized transceiver and a plurality of sensor nodes. Subordinate sensor nodes transmit data corresponding to sensed physical variables to a master node within a group.
