    摘要: 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.

    摘要: There is provided a capacitive pressure sensor comprising: a dielectric layer; a first electrode disposed on a first surface of the dielectric layer and to which a pressure is applied; a second electrode disposed on a second surface of the dielectric layer opposite to the first surface and including a plurality of unit electrodes having a predetermined shape; and a measuring device configured to detect a measurement value of a capacitance of the dielectric layer for each unit electrode by causing a potential difference between the first electrode and the second electrode. An electrode area of the unit electrode is determined using an actual measurement data indicating a relationship between a change amount of the measurement value detected for each unit electrode by the measuring device when a pressure is applied to the first electrode and the electrode area of the unit electrode and using a minimum value of the change amount of the measurement value determined by conditions including the number of detection steps of a pressure detected for each unit electrode by the measuring device.

    摘要: A martial arts training device with scoring system, device comprising a padded device designed to be struck by a participant; and a scoring system attached to padded device, scoring system comprising: an impedance-based impact sensing mechanism that detects a source of impact comprising at least one impedance changing mechanism that changes impedance as each of conductive material is moved towards and away from impedance changing mechanism as the first participant delivers the impact; an impact sensing mechanism for which mechanically detects the force of impact creating electrical charges; at least one impedance-based impact measuring scoring system determining the source of the impact that occurred based on a change in impedance electromagnetically in said impedance changing mechanism; and at least one impedance changing rate determination engine configured to determine a rate at which the impedance changes in impedance changing mechanism; and at least one impact force determination engine configured to determine a magnitude of a force of the impact based on the rate at which the impedance changes in impedance changing mechanism and the impedance changing a rate data.
