Publication number: 20240142319Abstract: 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.Type: ApplicationFiled: January 5, 2024Publication date: May 2, 2024Inventors: Yodai MATSUMURA, Takashi MATSUMOTO, Susumu URAGAMI, Yuta MORIURA, Takafumi HAMANO, Hiroyuki FURUYA

Publication number: 20240085256Abstract: 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.Type: ApplicationFiled: November 13, 2023Publication date: March 14, 2024Inventors: Yodai MATSUMURA, Takashi MATSUMOTO, Susumu URAGAMI, Yuta MORIURA, Takafumi HAMANO, Hiroyuki FURUYA

Publication number: 20230332961Abstract: A load sensor includes: two base members disposed so as to face each other; two electrically-conductive elastic bodies respectively disposed on opposing faces of the two base members; and a plurality of conductor wires disposed between the two electrically-conductive elastic bodies. The plurality of conductor wires are disposed under a condition that, when a diameter of each conductor wire is not greater than 0.3 mm, a gap between the plurality of conductor wires is not less than 0.6 mm, and when the diameter of each conductor wire is greater than 0.3 mm, the gap between the plurality of conductor wires is not less than twice the diameter of each conductor wire.Type: ApplicationFiled: June 23, 2023Publication date: October 19, 2023Inventors: Susumu URAGAMI, Hiroyuki FURUYA, Yuta MORIURA, Takashi MATSUMOTO, Hironobu UKITSU, Yodai MATSUMURA

Publication number: 20220357220Abstract: 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.Type: ApplicationFiled: July 27, 2022Publication date: November 10, 2022Inventors: Susumu URAGAMI, Hiroyuki FURUYA, Yuta MORIURA, Takashi MATSUMOTO, Hironobu UKITSU, Yodai MATSUMURA
