摘要：
A semiconductor distortion sensor comprises a flexible cantilever having a free end portion and a fixed end portion. A p-type region and an n-type region define a pn junction formed in a preselected region of the cantilever where stress-caused distortion occurs due to flexure of the cantilever upon displacement of the free end portion of the cantilever. When the free end portion of the cantilever is subjected to displacement, the cantilever is flexed and the amount of displacement of the free end portion of the cantilever is detected on the basis of a change in an electrical characteristic of the pn junction.
