Composition of a high sensitivity sensor for detecting mechanical quantity

摘要

A composition of a high sensitivity sensor for detecting mechanical quantity comprising: an insulating matrix material; a conductive path formed by discontinuously dispersing second phase particles of a conductor or a semiconductor into the insulating matrix material at an interparticle distance from 0.001 to 1 mu m; and a structure for holding residual mechanical quantity which is the same kind of mechanical quantity to be detected and previously applied along a loading direction of the mechanical quantity to be detected; thereby imparting the high sensitivity in the mechanical quantity to the composition. <IMAGE>
