    摘要: The present disclosure concerns a pressure sensor, comprising at least two adjacent electrically conductive leads disposed in a pattern on a face of a first elastomeric carrier; and an electrically resistive layer formed of a electrically resistive composite material for shunting the at least two adjacent electrically conductive leads, said electrically conducting layer disposed on a face of a second elastomeric carrier. The first and second carriers are stacked across a spacer such that the at least two adjacent electrically conductive leads faces the electrically resistive layer across a gap defined by the spacer. The gap is formed by a pocket between the carriers. The first carrier including the at least two adjacent electrically conductive leads and/or the second carrier including the electrically resistive layer are stretchable such as to upon receiving a force, exerted in a direction across the gap, reduce the gap between the electrically resistive layer and the at least two adjacent electrically conductive leads. Upon closing the gap the adjacent electrically conductive leads are shunted over a force dependent contact area and contact resistance. A gas in a gas confining structure between the carriers at least partly counteracts the exerted force.

    摘要: This pressure sensor is configured to detect pressure. The pressure sensor comprises a first sheet member and a second sheet member. The second sheet member is disposed so as to overlie the first sheet member. First and second electrodes are formed on the first sheet member. A third electrode which is covered by a pressure-sensitive electroconductive layer is formed on the second sheet member. When the pressure sensor is being used, a voltage is applied between the first and second electrodes. Regardless of whether the pressure sensor is being used, the first and second electrodes are each in contact with the pressure-sensitive electroconductive layer.

    摘要: The present invention relates to a flexible sensor strip for measuring geometric shapes, in particular bending radii or the like, and to an associated device which can process and evaluate sensor signals of the sensor strip. The sensor strip comprises a substrate, on which a plurality of resistor pairs is arranged. Each of these resistor pairs has a resistor on the substrate front side and a further resistor on the substrate rear side. Both of these resistors are connected in series and between the poles of a supply voltage so that they form a voltage divider. The special feature of the present invention is that an electrical via and/or a pair of electrically interconnected contact elements is provided for the series circuit, that is, for the connection between the two resistors. When the substrate or the sensitive region of the sensor strip is moved into itself, in particular in the event of bending and/or twisting (torsion), the mid voltages in the affected voltage dividers change. This is sensed and evaluated by the measuring device according to the invention.
