Abstract:
In this paper, the authors propose a novel shearing force measurement device using an integrated micro optical displacement sensor and a frame. The 3 mm x 3 mm square and 0.7 mm thick sensor tip measures the mirror tilt angle on the underside of the frame caused by the shearing force applied to the upper surface of the frame. The authors obtained a linear output change for a single axis shearing force, and expect to be able to detect the magnitude and direction of the shearing force. In addition, it is possible to measure biaxial shearing forces and alter the measurement range and resolution by varying the frame material and shape.
