Abstract

The present invention relates to a force measurement device that includes mechanical amplification of linear elastic deformation along the axis of loading by estimating the quasi-linear incremental displacement between two points on arcs inscribed due to angular movements of a pair of cantilever arms located on opposite quadrants on a closed contour load sensing element to improve the sensitivity, and hence the resolution, of the force measurement device.
