Abstract: A load sensor includes: a first base member; a second base member; a plurality of electrically-conductive elastic bodies disposed so as to be arranged; a plurality of conductor wires crossing the plurality of electrically-conductive elastic bodies; a dielectric body disposed between the electrically-conductive elastic body and the conductor wire; and a thread configured to sew and fasten the plurality of conductor wires to the first base member or the second base member by a stitch row extending in a direction crossing an arrangement direction of the plurality of electrically-conductive elastic bodies. At a position of the stitch row, one of the conductor wires crosses or is close to another of the conductor wires. The thread is sewn so as to extend across the one conductor wire and the other conductor wire.

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; a wire member that is electrically conductive and disposed between the second base member and the electrically-conductive elastic body; and a dielectric body disposed between the electrically-conductive elastic body and the wire member. A permittivity of the dielectric body is changed in a contact surface direction in which contact of the dielectric body advances in association with increase in a load, such that a form of change in capacitance between the electrically-conductive elastic body and the wire member associated with change in the load becomes close to that of a straight line.

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: A load sensor includes: a base member having a flat plate shape; a plurality of electrically-conductive elastic bodies disposed so as to extend in a first direction on an upper face of the base member; at least one electrically-conductive member extending in a second direction and crossing the plurality of the electrically-conductive elastic bodies; a dielectric body disposed between the plurality of electrically-conductive elastic bodies and the electrically-conductive member; and a plurality of wires respectively connected to the plurality of electrically-conductive elastic bodies and disposed so as to extend in the second direction on the upper face of the base member. Each wire is disposed at a position where the wire does not overlap with the electrically-conductive member, and is insulated at least in a range where the wire overlaps with the electrically-conductive elastic body other than the electrically-conductive elastic body serving as a connection target.
