In a pressure-sensitive touch sensor of a capacitance type, a first electrode and a second electrode are provided on a first surface of a base material sheet. The base material sheet is folded between the first electrode and the second electrode so that a surface of the first electrode and a surface of the second electrode face each other. The base material sheet is folded at a fold line portion in which a slit is formed. An elastic layer is provided between folded parts of the base material sheet. The pressure-sensitive touch sensor is configured to detect pressing on the operation surface based on a change in capacitance, which is caused when the elastic layer is compressed and deformed in a thickness direction by a pressing force to reduce a distance between the first electrode and the second electrode.

Pressure-sensitive touch sensor and pressure-sensitive touch sensor module

A capacitive three-dimensional sensor includes: a light-guide unit having a side surface and an operation surface, the side surface being formed along the Z direction and including a light entering portion, through which light from a light source enters, the operation surface being configured to input the inputs and including a light output portion, from which the light exits; a sheet-like X-Y electrode body configured to sense the inputs in the plane X and Y directions; a deformable body including a sheet-like elastic body; and a sheet-like Z electrode body configured to sense the input in the Z direction. The light-guide unit includes an optional decorative sheet, and a light-guide sheet to guide the light that has entered the light-guide unit from the side surface and output the light toward the light output portion. A total of bending stiffnesses of the light-guide sheet and decorative sheet is less than 256.

Capacitive three-dimensional sensor

A production method of a capacitive sensor sheet, comprising: a film forming step forming of a optically-transparent electroconductive filmon the surface of a substratehaving optical transparency; a supplemental electrode forming step of setting an electrode regionwhich functions as the transparent electrodeat least in part of the film, and laminating a supplemental electrodewhich has a lower electrical resistance than the electrical resistance of the filmto cover at least part of a periphery of the electrode region; a wire forming step of laminating a wirein which one end thereof is connected to the supplemental electrodeon the film; a resist laminating step of laminating a resistto cover all of the electrode regionand at least part of the supplemental electrode; and a conductive film removing step of removing a part of the filmformed on the substratehaving optical transparency placed at a position not overlapping with the resist, the supplemental electrode, or the wire

Capacitive sensor sheet and production method thereof

In a capacitive input switch that is accommodated in a housing of electronic equipment, the capacitive input switch includes a rigidity imparting layer having rigidity and a laminate sheet laminated on the rigidity imparting layer. The rigidity imparting layer and the laminate sheet are three dimensionally formed. The laminate sheet is formed by a substrate sheet, a conductive pattern layer for capacitor formation, and a decorative layer that is laminated at least on any one of the substrate sheet and the conductive pattern layer. A separate conductor is caused to contact with the conductive pattern layer and the conductive pattern layer is caused to be electrically connected to an external electric circuit by the conductor.
