  • Publication number: 20160041652
    Abstract: Input devices are provided. In accordance with an example embodiment, an input device includes an interface layer that flexes in response to pressure, a plurality of sense electrodes, a dielectric between the sense electrodes and the interface layer, and interconnecting circuitry. The dielectric compresses or expands in response to movement of the interface layer, and exhibits dielectric characteristics that vary based upon a state of compression of the dielectric. The interconnecting circuitry is to the sense electrodes and provides an output indicative of both the position of each sense electrode and an electric characteristic at each sense electrode that provides an indication of pressure applied to the dielectric adjacent the respective sense electrodes.

  • Patent number: 9212960
    Abstract: Apparatuses and methods, consistent with embodiments herein, are directed to an apparatus having a stretchable substrate and a plurality of nanostructures. While the plurality of nanostructures are adhered to the stretchable substrate, the stretchable substrate and the nanostructures are stretched and/or operate in a stretched mode in which the nanostructures are characterized by a resistance corresponding to a strain imparted due to the stretching. When the substrate is relaxed or the stretching otherwise lessened, the nanostructures continue to be characterized as a function of the strain and the corresponding resistance, with buckled segments of the nanostructures being adhered along a surface of the substrate.

  • Publication number: 20140350348
    Abstract: Aspects of the present disclosure are directed to pressure sensing. As may be implemented in accordance with one or more embodiments, an external energy field is applied to a resonant circuit having inductive conductors separated by a compressible dielectric, for wirelessly detecting pressure. Specifically, the resonant circuit is responsive to the energy field and applied pressures by operating in respective states exhibiting different resonant frequencies that are based upon pressure-related compression of the compressible dielectric. These resonant frequencies, or a change in the resonant frequencies, can be used as an indication of the pressure.

  • Publication number: 20140318440
    Abstract: A coated substrate is formed with aligned objects such as small molecules, macromolecules and nanoscale particulates, such as inorganic, organic or inorganic/organic hybrid materials. In accordance with one or more embodiments, an apparatus or method involves an applicator having at least one surface patterned with protruded or indented features, and a coated substrate including a solution-based layer of objects having features and morphology attributes arranged as a function of the protruded or indented features.
