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; an electrically-conductive member having a linear shape 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 electrically-conductive member. The electrically-conductive member has a bent shape that is bent in a direction toward the electrically-conductive elastic body.

Abstract: A load detecting device includes a load sensor and a sealing member encapsulating the load sensor. The sealing member includes a lower sealing member on which the load sensor is placed, an upper sealing member covering an upper face of the load sensor and joined to the lower sealing member, and an air pressure adjustment structure configured to cause an air pressure in an accommodation space, of the load sensor, formed by the lower sealing member and the upper sealing member to be approximately equal to an outside air pressure.

Abstract: A load sensor includes: a first base member; a second base member; a plurality of electrically-conductive elastic bodies formed so as to extend in a first direction on an opposing face of the first base member; a plurality of conductor wires extending in a second direction crossing the first direction between the first base member and the second base member; 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 or second base member. A plurality of stitch rows, of the thread, in each of which stitches are arranged in the first direction are formed at a predetermined pitch in the second direction. Waving that supports a load does not occur, at least in a load detection range, in the target base member.

Abstract: A load sensor includes: an electrically-conductive elastic body; an electrically-conductive member having a linear shape and disposed so as to cross the electrically-conductive elastic body; and a dielectric body disposed between the electrically-conductive elastic body and the electrically-conductive member. A width of the electrically-conductive elastic body in a longitudinal direction of the electrically-conductive member is changed such that a relationship between a load and a contact area between the electrically-conductive elastic body and the electrically-conductive member via the dielectric body becomes close to a linear relationship.

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.
