Paper Abstract

A sub-millimeter three-component force sensor is developed using silicon microfabrication technology. A polysilicon cross-beam, 300 micrometer by 300 micrometer, with twelve piezoresistive strain gauges integrated on it, is the elastic element of the sensor. The strains detected by the strain gauges are measures of the three orthogonal components of the force applied at the center of the cross-beam. For calibration purposes, electromagnetic forces are generated on an aluminum cross-beam that is suspended over the sensor structure. A 10 (mu) N resolution is obtained for each of the three force components.
