  • Publication number: 20220310899
    Abstract: An element includes an upper electrode, a flexible intermediate layer, and a lower electrode. The upper electrode having an uneven structure. The lower electrode is closely attached to the intermediate layer. The element is configured to generate an electrical signal due to contact and separation between the upper electrode and the intermediate layer. The lower electrode is configured to take a shape fittable to the uneven structure when the upper electrode and the intermediate layer come into contact with each other.

  • Patent number: 10714676
    Abstract: A sensor includes a plurality of elements and an insulating layer. The plurality of elements is deformable to generate power. The insulating layer is interposed between the plurality of elements. Each of the plurality of elements includes a pair of electrodes and an intermediate layer. The intermediate layer is disposed between the pair of electrodes and formed of one of a rubber and a rubber composition.

  • Patent number: 10458816
    Abstract: A sensor includes an electrode, an insulator, a pressure receiver, and a pressure imparting unit. The insulator is disposed at a position facing the electrode and away from the electrode. The pressure receiver is disposed on a surface of the insulator on a side opposite to the electrode. The pressure imparting unit presses a part of the insulator toward the electrode at a position different from the pressure receiver to contact the insulator with the electrode. The insulator generates power by contact charging or separation charging with respect to the electrode, to output the power as a signal.

  • Publication number: 20180149685
    Abstract: A sensor includes a first detector and a second detector. The first detector detects an electromagnetic noise varying according to a distance between the sensor and a human body and changes an output according to the electromagnetic noise detected. The second detector detects a detection load applied to a detection surface of the sensor and changes an output according to the detection load.
