  • Robust, wireless microelectro mechanical system (MEMS) shear force sensor
    Patent number: 6736015
    Abstract: Micro electromechanical components in a novel configuration to allow wireless normal direction pressure transducers to be used for oblique or shear forces. The invention includes a novel cantilever beam configuration and algorithm, the readings of the MEMS sensors are averaged to reduce the experimental variability, to estimate the shear stress that may occur between a human and external equipment or possibly between materials. The shear force component is calculated via the formula: Shear Force=Vt={square root over ({overscore (V)})}23+4+ . . . +n1−{overscore (V)}21+2+ . . . +n2.
