1. An apparatus for measuring a shearing force upon sitting, comprising:

  • a shearing force sensor disposed in a specific area of a seat and configured to sense a shearing force generated by a shearing force sensor upon an individual sitting in the seat;

    a signal processor configured to filter and amplify a signal received from the shearing force sensor and convert an amplified analog signal into a digital signal; and

    a monitoring device configured to analyze the signal converted by the signal processor and display the signal on a screen, wherein a shear force resulting from an individual sitting in the seat is measured in all directions by the apparatus,the shearing force sensor includes a lower plate, a middle plate, and an upper plate that are stacked in a three-layered structure, andthe middle plate includes;

    a cross-shaped strain gauge fixing plate inducing independent strains by disposing strain gauges in transverse and longitudinal directions attached thereto, anda fixing part separately disposed across the strain gauge fixing plate and configured to allow the strain gauge fixing plate to be fixed between the lower plate and the upper plate, responding to all directions of shearing forces.
