Description

Capacitive force sensor switch {CAPACITIVE FORCE SENSOR SWITCH}

The present invention relates to a capacitive force sensor switch, and more particularly, to a capacitive force sensor switch having a structure that minimizes deterioration of sensitivity over time by allowing a force sensor to maintain its original state even after prolonged use.

Generally, a capacitive force sensor is applied to measure a static or dynamic pressure by detecting a change in capacitance that is variable by pressure, or to generate a switching signal having a continuous change.

FIG. 1 is a view showing the structure of a general non-contact type capacitive force sensor, and FIG. 2 is a diagram showing the structure of a conventional inductive capacitive force sensor.

As shown in FIG. 1, the non-conductive capacitive force sensor of the related art includes a fixed electrode mounted on an insulator substrate and a variable electrode such as a diaphragm as another electrode disposed at a fixed distance from the fixed electrode. That is, in the present invention, the force sensor constituted by forming the electrostatic capacitance without grounding the variable electrode and the fixed electrode is defined as a non-contact capacitive force sensor.

As shown in FIG. 2, the conventional inductive capacitive force sensor includes a capacitance portion mounted on an insulator substrate, and a variable electrode portion having a variable electrode arranged to be spaced apart from the capacitance portion by a predetermined distance. That is, in the present invention, a force sensor having a structure in which a capacitance for switching a capacitance portion is formed and a variable electrode for varying a capacitance of the capacitance portion is grounded is defined as a grounded capacitance force sensor.

When the variable electrode is deformed by an external pressure, the capacitive force sensor according to the related art having the above-described configuration measures the static pressure and the dynamic pressure according to the variation of the capacitance, or outputs the switching signal corresponding to the static pressure or dynamic pressure .

Compared with general tect switch, it can not perform 0 point adjustment in case of general tect switch with instrument error. Accordingly, the conventional tect switch has a problem of performing an undesired switching operation due to a mechanical error. On the other hand, in the case of the force sensor, when the variable electrode is deformed, the capacitance value at the corresponding position is set to zero, thereby facilitating adjustment of the zero point despite the error of the mechanism, and the sensitivity is remarkably high. Recently, capacitive force sensors have been widely used.

The capacitive force sensor is applied to an electronic device having a force touch function, a pressure sensitive touch panel, a touch jog shuttle for automobile, a metal touch panel switch, etc., so that the variable electrode is varied according to the external pressure, To change the capacitance, to sense the changed capacitance, and to output a pressure signal or a switching signal.

In this case, the variable electrode constituting the above-described capacitive force sensor is repeatedly deformed and then restored by the elastic force. Such restoration by the elastic force prevents the deformable electrode from being completely restored to its original state. Therefore, when the capacitive force sensor is continuously used for a long period of time, the variable electrode is continuously deformed due to accumulation of deformation, so that accurate pressure detection can not be performed. Accordingly, there is a problem that the user is required to perform repetitive zero-point adjustment.
