Abstract: A capacitance element electrode is formed on a first surface of FPC, and a displacement electrode is formed on a second surface of the FPC. The FPC is folded at its connecting portion in such a manner that the first surface and the second surface are opposite to each other, whereby a capacitance element is formed between the capacitance element electrode and the displacement electrode.

Abstract: In a capacitance type sensor of the present invention, a capacitance element is constituted between a displacement electrode and a capacitance element electrode. A return-switch movable electrode is arranged above and spaced from the displacement electrode, to be placed in contact with the displaying electrode due to a displacement of a direction button. When the direction button is operated, the return-switch movable electrode is first displaced into contact with the displacement electrode. Then, the both make a displacement while keeping a contact state. When the displacement electrode is displaced to change the spacing to the capacitance element electrode, changed is the capacitance value of the capacitance element. Based on this change, a force is recognized. Herein, in the course of a transit from a state the displacement electrode and the return-switch electrode are not in contact to a state of their contact, the output signal varies necessarily beyond a threshold voltage.

Abstract: A sensor unit having capacitance element electrodes and a displacement electrode being opposite thereto is disposed on a substrate.

Abstract: A capacitance element electrode (E1) and a reference electrode (E31) are formed on a substrate (20) so as to be opposite to a displacement electrode (40). A dome-shaped movable switch electrode (E21) is disposed so as to be in contact with the reference electrode (E31) and at a distance from a fixed switch electrode (E11) formed inside the reference electrode (E31), and to cover the fixed switch electrode (E11). When an operation is applied to a detective member (30) and a portion of the movable switch electrode (E21) in the vicinity of its top is displaced to be brought into contact with fixed switch electrode (E11), a switch is turned ON. On the other hand, from a change in capacitance value of a capacitance element (C1) formed between the displacement electrode (40) and the capacitance element electrode (E1), the intensity of the force to the detective member (30) can be recognized.

Abstract: Capacitance element electrodes (E1 to E5) and a grounded reference electrode (E0) are formed on a substrate (20). At a position opposite to these electrodes (E0 to E5), a displacement electrode (40) is disposed that is Z-axially deformable as a detective member (30) is externally operated to move Z-axially. The displacement electrode (40) cooperates with the reference electrode (E0) and capacitance element electrodes (E1 to E5) to form capacitance elements (C0 to C5), respectively. Each of the capacitance elements (C1 to C5) is connected in series with the capacitance element (C0) with respect to a signal externally input. Changes in the capacitance values of the capacitance elements (C1 to C5) as the detective member (30) is moved are detected to sense the displacement of the detective member (30).

Abstract: A movable switch electrode (E21) which is contactable with a capacitance element electrode (E1) formed on a substrate (20) and is spaced apart from a fixed switch electrode (E11) formed in an interior of the capacitance element electrode (E1) and having a domed form to cover the fixed switch electrode (E11) is set in place. When a detective member (30) is operated and a force applied from a displacement electrode (40) to the movable switch electrode (E21) reaches a specified value, the movable switch electrode (E21) is elastically deformed and depressed drastically with buckling at the nearly top portion thereof and is brought into contact with the fixed switch electrode (E11). This brings the switch into the ON-state. At this time, an operator is given a pronounced click feeling.

Abstract: In a sensor sheet of the present invention, a large number of sensor cells, each having capacitance element electrodes corresponding to an X-axis direction, a Y-axis direction and a Z-axis direction and a displacement electrode arranged to form capacitance elements between the capacitance element electrodes and the displacement electrode, are arranged in matrix. This arrangement enables measurement of a distribution of three-dimensional components of the force applied from outside over the overall sensor sheet on the basis of the components of force detected in each of the large number of sensor cells.

Abstract: In a resistance type sensor of the present invention, a sensor unit having variable contact resistances and a wakeup switch formed in two layers is produced by folding a FPC forming thereon pressure-sensitive resistive inks, a displacement electrode connected to ground, and a displacement electrode held at a power-supply voltage Vcc. Accordingly, whenever operation is applied to an operating button, the displacement electrode and the displacement electrode are reliably contacted with each other, first, and, then, resistance values of the variable contact resistances are changed while the displacement electrodes are kept in their contacted state. This enables the operation applied to the operating button to be detected reliably.

Abstract: An intermediate displacement board (120) composed of a metal plate is arranged on a printed circuit board (110) having electrode patterns (E1-E7) and then a strain generative body (130) composed of silicon rubber is arranged on top thereof. Then, the arrangement is fixed to the printed circuit board (110) with attachments (140). Depressing a displacement portion (133) causes a connecting portion (132) to be deflected and an electrode (F0) to be brought into contact with the electrodes (E1, E2) to make them conductive, thereby allowing the pushbutton switch to be turned ON. Depressing further the displacement portion (133) causes an elastic deformation portion (134) to be elastically deformed and crushed and the intermediate displacement board (120) to be pushed downward. The capacitance of capacitors (C3-C7), which are constituted by the electrodes (E3-E7) and the intermediate displacement board (120), are varied according to the depression of the intermediate displacement board (120).

Abstract: A sensor for detecting levels of fluids and particulate matter is based on differences in dielectric constants of the various materials. The difference is reflected in different capacitance across electrodes immersed to different depths in such materials. A square-wave clock pulse is input into circuit composed of the capacitance and a resister in series. The output voltage is fed into a logic unit (such as exclusive-OR), which converts the exponential decay of the voltage into a pulse of uniform height with duration proportional to the time constant (proportional to the capacitance) of the exponential decay. The pulse is optionally fed through a low-pass filter to give a signal proportional to the duration.
