Patent number: 9677952Abstract: 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.Type: GrantFiled: August 17, 2015Date of Patent: June 13, 2017Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Zhenan Bao, Chee-Keong Tee, Stefan Christian Bernhardt Mannsfeld, Justin P.

Patent number: 9520563Abstract: Organic semiconductor material can be patterned from a solution onto a substrate by selectively wetting the substrate with the solution while applying a mechanical disturbance (such as stirring the solution while the substrate is immersed, or wiping the solution on the substrate). The organic semiconductor material can then be precipitated out of the solution, for example to bridge gaps between source and drain electrodes to form transistor devices. In some embodiments, the solution containing the organic semiconductor material can be mixed in an immiscible host liquid. This can allow the use of higher concentration solutions while also using less of the organic semiconductor material.Type: GrantFiled: November 20, 2008Date of Patent: December 13, 2016Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Stefan Christian Bernhardt Mannsfeld, Armon Sharei, Zhenan Bao
