Abstract
A displacement transducer capable of measuring very small displacements (on the order of 100 &mgr;m or less) comprises a strain gage mounted to the curved arc of a substrate. The transducer has a resolution of at least 10 &mgr;m, preferably at least 1 &mgr;m or better. The transducer can measure positive or negative displacement in a specimen and can also be used as an extremely sensitive load cell for very high resolution weight, load or mass determinations.
