Abstract: The invention provides a novel capacitive device configured to detect differences in an applied force over a continuous range of applied force that includes zero force. The device includes first and second electrodes that are spaced apart a predetermined distance from each other in a rest position. A measurable capacitance exists between the first and second electrodes. Structured elements having a predetermined maximum dimension are positioned in the device to control the predetermined distance between the first and second electrodes. An applied force to the device causes a change in the distance between the first and second electrodes and a related change in the capacitance that can be measured to determine information related to the applied force.

Abstract: The invention provides a force detector in which power consumption is suppressed. Four electrodes E11 through E14 are formed on a substrate, and an elastic deformable body formed of a rubber film is disposed thereon. A conductive coating is applied on the lower surface of the elastic deformable body to provide a displacing conductive layer 26. Four capacitance elements C11 through C14 are comprised by the electrodes E11 through E14 and the displacing conductive layer 26 opposed to the electrodes. The capacitance values thereof are converted into voltage values V11 through V14 by C/V converter circuit 50, and based on operation by signal processing circuit 60, an external force applied to the elastic deformable body is detected. A pair of contacting electrodes E15 and E16 are formed on the substrate, and when an external force with a predetermined strength or more is applied, the elastic deformable body deforms, and the displacing conductive layer 26 comes into contact with both electrodes E15 and E16, simultaneously. The potential of the electrode E16 is taken-in from the terminal T5, and when said potential is Vcc, the C/V converter circuit 50 is operated in a standby mode with less power consumption, and when said potential is GND, the circuit is operated in a normal mode.

The difference between these two different distances can be changed—more particularly, reduced—by deformation of at least one capacitor pole element (1,3) when the capacitor is subjected to pressure.

Abstract: A capacitance type load sensor is provided with outer and inner tubes made of plastic and formed into a hollow circular cylinder shape and outer and inner electrodes respectively attached to the inner and outer peripheral faces of the outer and inner tubes. A coil spring is disposed within the interior space of the inner tube, and load-applied hooks of the coil spring are individually coupled to respective end walls of the outer and inner tubes. When a tensile load is applied to the hooks of the coil spring and hence the coil spring is elongated, a relative motion occurs between the outer and inner tubes so that the facing area between the outer and inner electrodes and accordingly the capacitance between these electrodes decrease. The load sensor measures the applied load based on an amount of change in the capacitance between before and after the application of the load.
