  • Publication number: 20240118151
    Abstract: A sensing data correction system corrects sensing data acquired from a glove-type wearable sensor in which a film-like pressure sensor is incorporated into a fingertip, and includes a data correction unit for correcting the sensing data. Three coordinate axis directions in a three-dimensional orthogonal coordinate system are assumed to be a vertical direction, a longitudinal direction of the pressure sensor, and a width direction of the pressure sensor, and the pressure sensor is obtained by laminating one flexible printed circuit, one sheet-like pressure sensitive element, and one protective film in the vertical direction. An upper surface of the flexible printed circuit and a lower surface of the pressure sensitive element are bonded and fixed to each other, and an upper surface of the pressure sensitive element and a lower surface of the protective film are bonded and fixed to each other. The data correction unit executes sensing data correction processing.
