Patent number: 10794779Abstract: Object: To provide a pressure sensor that can provide a reduced sensation of a foreign body and that has a good sensitivity to pressure from a low load region to a high load region. Resolution means: The pressure sensor includes a variable resistor and a plurality of electrodes. The variable resistor is made of an electrically conductive foam elastomer material. The electrically conductive foam elastomer material is a material imparted with electrical conductivity by dispersing electrically conductive fillers into an elastomer material and obtained by foaming the elastomer material. The plurality of electrodes are disposed at intervals from each other on one surface in contact with the variable resistor.Type: GrantFiled: December 5, 2017Date of Patent: October 6, 2020Assignee: KITAGAWA INDUSTRIES CO., LTD.Inventors: Kazuki Yamada, Yasuo Kondo

Patent number: 10629337Abstract: A pressure sensor includes a variable resistance portion, and a first electrode and a second electrode. The variable resistance portion includes a conductive foam elastomer material. When pressure is applied to the variable resistance portion, the variable resistance portion is compressed in accordance with the pressure. As the compression amount increases, the electric resistance of the variable resistance portion decreases. The first electrode and the second electrode are configured to contact with the variable resistance portion at a location having an interval of 0.5 mm or greater with each other, therefore being electrically connected via the variable resistance portion.Type: GrantFiled: November 8, 2017Date of Patent: April 21, 2020Assignee: KITAGAWA INDUSTRIES CO., LTD.Inventors: Kazuki Yamada, Yasuo Kondo, Lu Zhao
