Abstract: Disclosed is a robust tactile sensor array that mimics the human fingertip and its touch receptors. The mechanical components are similar to a fingertip, with a rigid core surrounded by a weakly conductive fluid contained within an elastomeric skin. It uses the deformable properties of the finger pad as part of the transduction process. Multiple electrodes are mounted on the surface of the rigid core and connected to impedance measuring circuitry within the core. External forces deform the fluid path around the electrodes, resulting in a distributed pattern of impedance changes containing information about those forces and the objects that applied them. Strategies for extracting features related to the mechanical inputs and using this information for reflexive grip control.

Abstract: A generally flexible pressure sensing mat for a vehicle seat includes a first carrier foil and a second carrier foil arranged at a certain distance from each other by means of a spacer. The mat includes a plurality of cells, each cell being defined by a respective opening of the spacer. In each cell, at least two electrodes are arranged between the first and second carrier foils and, in response to pressure acting on the pressure sensing mat at a cell, the first and second carrier foils are pressed together against the reaction force of the carrier foils thereby causing variation of an electrical resistance between the at least two electrodes of the cell. The pressure sensing mat includes at least one rigidifying element, the least one rigidifying element being associated to an individual cell for locally reducing flexibility of the pressure sensing mat at the individual cell.

Abstract: A hybrid tactile sensor includes a flexible cloth-based tactile sensor array including a plurality of electrodes, each of the electrodes connected to a corresponding connecting zone of an intermediate connecting harness made from a flexible film such as Kapton®. The harness includes a common bundle of parallel conductors etched or printed onto the harness and connecting each of the connecting zones to a common terminal for further attaching to a control unit of the sensor. The use of the harness allows repeatable manufacturing of sensor arrays with large number of electrodes or when they are located close to each other. Each connecting zone may include an interconnecting pad for crimping, soldering, or adhering the electrode thereto using a conductive epoxy. Alternative embodiments describe the use of U-shaped malleable connectors, jumper wires including those equipped with U-shaped clips, and other means of attaching electrodes to corresponding connecting zones. The use of alternating connections with electrodes of the array allows to double the distance between individual electrodes available for making a connection.

Abstract: The cost and complexity of an electronic pressure sensitive transducer are decreased by constructing such a transducer directly on a printed circuit board containing support electronics. Conductive traces are formed on the printed circuit board to define a contact area. A flexible substrate having an inner surface is positioned over the contact area. An adhesive spacer, substantially surrounding the contact area, attaches the flexible substrate to the printed circuit board. At least one resistive layer is deposited on the flexible substrate inner surface. In use, the resistive layer contacts at least two conductive traces in response to pressure applied to the flexible substrate to produce an electrical signal indicative of applied pressure.

Abstract: The present invention provides methods for connecting electrically conductive elastomer to electronics that reduce cost and time for manufacturing a tactile sensor that includes an electrically conductive elastomer such as a conductive foam. The methods provide a good connection between the electrically conductive elastomer and the electrodes connected to the electronics, which provide for repeatable measurements. The methods can be used for all cases of electrically conductive elastomers and elastomers made to be conductive with the addition of conductive particles (such as carbon, silver, nickel, gold, etc.) including thermoplastic and some thermosetting elastomers.

Abstract: A pressure sensor includes a pair of base films, a pair of electrodes, a layer of pressure-sensitive resistor, a spacer, and a projection. The electrodes are located between the base films. The layer of pressure-sensitive resistor is located between the base films to be distant from one of the electrodes by a predetermined gap. The spacer is located outside the layer of pressure-sensitive resistor between the base films and used for forming the gap. The projection is located on an outer surface of one of the base films in order to decrease the lowest pressure that can be detected by the pressure sensor. The contact state between the layer of pressure-sensitive resistor and one of the electrodes varies to vary the resistance between the electrodes when a pressure acts on the projection.
