LOAD DETECTION SENSOR USED TO DETECT LOAD HAVING BEEN APPLIED TO STRUCTURE IN PAST AND LENGTH ADJUSTING METHOD, FOR SENSITIVITY, OF EVERY SENSING ELEMENT IN SAID LOAD DETECTION SENSOR

摘要

PURPOSE: To always an simultaneously fracture all crude fibers in node parts and to always stably cause a sudden change in an electric resistance by a method wherein the node parts are formed in individual sensing elements. ;CONSTITUTION: Sensing elements S₁, S₂, S₃ are arranged in parallel on a base material 2, both ends of the individual sensing elements S₁, S₂, S₃ are connected to common terminals 3a, 3b, and respective lengths, for sensitivity, which become sequentially long from ends by prescribed differences are given to the individual sensing elements S₁, S₂, S₃. Then, node parts F₁, F₂, F₃ as fracture promotion means are formed in the individual sensing elements S₁, S₂, S₃. When a tension state is caused, the individual sensing elements S₁, S₂, S₃ are fractured sequentially in the respective node parts F₁, F₂, F₃, and electric resistance values according to the degree of their destruction are obtained.;COPYRIGHT: (C)1995,JPO
