Abstract: A load sensor is configured to detect, as change in capacitance, change, in a contact area between an electrically-conductive elastic body and a dielectric body, that occurs due to a load applied to an upper face of the load sensor. In the load sensor, a plurality of sensor parts each configured to detect the load are disposed so as to be arranged in a plane direction, and a buffer part configured to suppress displacement of the upper face due to the load applied to a first sensor part from being propagated to a second sensor part adjacent to the first sensor part is disposed between the first sensor part and the second sensor part.

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.
