    Abstract: Achieving high spatial resolution in contact sensing for robotic manipulation often comes at the price of increased complexity in fabrication and integration. One traditional approach is to fabricate a large number of taxels, each delivering an individual, isolated response to a stimulus. In contrast, proposed sensor includes a continuous volume of soft material, e.g., a piezoresistive elastomer with a number of terminals embedded inside. Piezoresistive effects can be measured between all pairs of terminals in the set, and this rich signal set can contain the information needed to pinpoint contact location with high accuracy using regression algorithms. Submillimeter median accuracy can be demonstrated in locating contact on a 10 mm by 16 mm sensor using only four terminals (creating six unique pairs). In addition to extracting more information from fewer wires, this approach lends itself to simple fabrication methods and makes no assumptions about the underlying geometry, simplifying future integration on robot fingers.

    Abstract: A touch-type variable resistor structure includes a resistor-base plate, a conductive base plate and a separator member. The resistor-base plate further includes a main plate body and a resistance layer. The resistance layer extended along an extension direction is located on the main plate body. The conductive base plate located on the resistor-base plate includes an electricity-conductive layer facing the resistor-base plate. The separator member located between the resistor-base plate and the conductive base plate further has a central opening. One of the main plate body and the main conductive plate body is formed as a flexible-touch base plate. While the flexible-touch base plate is depressed, part of the electricity-conductive layer would pass through the central opening to electrically couple the resistance layer.

    Abstract: An electrically responsive composite material (1110) specially adapted for touch screen, comprising a carrier layer (1301) having a length and a width and a thickness (1303) that is relatively small compared to said length and said width. The composite material also comprises a plurality of electrically conductive or semi-conductive particles (201). The particles (201) are agglomerated to form a plurality of agglomerates (104, 1403) dispersed within the carrier layer such that each said agglomerate comprises a plurality of the particles (201). The agglomerates are arranged to provide electrical conduction across the thickness of the carrier layer in response to applied pressure such that the electrically responsive composite material has a resistance that reduces in response to applied pressure.

    Abstract: Pressure sensors having components with reduced variations due to stresses caused by various layers and components that are included in the manufacturing process. In one example, a first stress in a first direction causes a variation in a component. A second stress in a second direction is applied, thereby reducing the variation in the component. The first and second stresses may be caused by a polysilicon layer, while the component may be a resistor in a Wheatstone bridge.
