Abstract: A pressure sensitive transducer array in which a plurality of transducers are connected in series and in parallel with one another. In one embodiment, a resistive layer is formed from carbon or silver ink on a polyester film. A plurality of conductive shunt elements having greater conductivity than the resistive layer is formed on a second polyester film. The films are placed adjacent to one another with the shunt elements contacting the resistive layer. Voltage is applied across the resistive layer and pressure is applied thereto. As the pressure increases, the number of current paths set up through contact points on the shunt elements increase thereby decreasing the resistance across the resistive layer and increasing current flow. In another embodiment a plurality of plate elements are contained in a plane on one side of a dielectric layer. A plurality of plate elements are contained in a plane on the other side of the dielectric layer. As the layer is pushed together responsive to force applied, total capacitance as measured across the planes of plate elements varies.

Abstract: A sensor for sensing and quantifying the conformity of a workpiece surface contour to a predetermined design contour. The sensor consists of an array of capacitor elements on a surface having the negative image of the predetermined design contour, against which the workpiece is mated. In operation, each of the capacitor elements and the workpiece are connected to a corresponding oscillator circuit so that the frequency of each circuit is a function of the capacitance between the individual plate element and the workpiece, while the capacitance is a function of the distance between the individual plate element and the workpiece. Hence the overall output of the circuits is a function of the conformity of the workpiece surface contour to the contour or topology of the sensor surface.

Abstract: A pressure-sensitive transducer arrangement comprises a matrix of transducer elements which are formed at the points of intersection of row conductors (35, 36) and column conductors (5 to 7). A flat substrate (2) is provided with column conductors (5 to 7), each of which is covered with a similarly-structured piezoceramic material as a dielectric medium (15 to 17). This piezoceramic material is separated from the row electrodes (35, 36) by empty spaces (24 to 26). Due to bilateral spacing of less than 100 micrometers for the row conductors and column conductors, a sensor matrix is produced with a dense packing of pressure-sensors functioning as capacitors which are formed at the cross-points of the row and column conductors. These sensors are particularly adapted for use in the gripping device of an industrial robot and make it possible to detect and determine the position of robot workpieces.

Abstract: A pressure sensing device (1000) comprises first and second electrodes (10, 20) spaced from each other by a distance. At least one of the electrodes is formed of/comprises a unitary piece of non-metallic conductive material. The distance is changeable in response to a pressure/force applied to the first and/or second electrode. The device comprises a measurement module (500) connected to the first/second electrode at a plurality of sensing points (S1 . . . ). The measurement module is configured to measure a change in capacitance between the first and second electrodes, in response to a change in the distance when a pressure/force is applied to the first and/or second electrode, at each sensing point individually and/or at all sensing points simultaneously. The measurement module is configured to determine the location, area and amount of applied pressure on the first and/or second electrode from the individual measurements, and/or the amount of the applied pressure from the simultaneous measurement.
