Abstract: A load sensor includes: a first base member and a second base member disposed so as to face each other; an electrically-conductive elastic body disposed on an opposing face of the first base member; and a conductor wire disposed between the second base member and the electrically-conductive elastic body and configured as a plurality of element wires being twisted. Each element wire is configured as an electrically-conductive member which has a linear shape and of which the surface is covered by a dielectric body. A twist pitch of the plurality of element wires satisfies a conditional expression “p≤12nd”. In the expression, p is the twist pitch of the plurality of element wires, n is the number of the element wires included in the conductor wire and d is the outer diameter of each element wire.

Abstract: Provided is a pressure-sensitive element having a relatively wide measurement range of a pressing force and a relatively simple structure while having more sufficient stretchability. A pressure-sensitive element includes a base material, a plurality of conductor wires, a plurality of dielectrics, and a filamentous member. The base material includes an elastic conductor having elasticity and conductivity. Further, the base material has a sheet shape. The plurality of conductor wires are arranged in parallel so as to individually intersect with the elastic conductor in plan view. Further, each of the plurality of conductor wires has a plurality of inflection parts. The plurality of dielectrics are arranged between the elastic conductor and the plurality of conductor wires. The filamentous member elongates so as to intersect with the plurality of conductor wires in plan view. Further, the filamentous member sews the plurality of conductor wires to the base material.

Abstract: A capacitance detection device includes: a sensor unit including a plurality of sensor elements; row control lines; column control lines; a control circuit supplying a charging voltage to the sensor element; and an equipotential circuit outputting a potential equal to the potential of the sensor element subject to measurement. The control circuit applies a charging voltage to the row control line connected to the sensor element and connects the column control line connected to the sensor element to the ground potential side. The control circuit causes the equipotential circuit to set a potential of at least one of the row control lines other than the row control line connected to the sensor element subject to measurement and the column control lines other than the column control line connected to the sensor element subject to measurement to a potential equal to the potential of the sensor element subject to measurement.
