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.

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: an electrode; a dielectric body disposed on a surface of the electrode; an electrically-conductive elastic body that is disposed so as to be opposed to the dielectric body and of which a surface on the dielectric body side has a projection formed thereon; a substrate configured to support the electrically-conductive elastic body; and a configuration (projection) that suppresses movement of the electrically-conductive elastic body in a horizontal direction.

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.

CPC classification number: G01L1/142

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 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 disposed between the second base member and the electrically-conductive elastic body; a dielectric body disposed between the electrically-conductive elastic body and the electrically-conductive member; and a component configured to change a contact area of the dielectric body in association with increase in a load, such that a form of change in capacitance between the electrically-conductive elastic body and the electrically-conductive member associated with change in the load becomes close to that of a straight line.
