STRAIN SENSOR, MONITORING SYSTEM AND METHOD OF MANUFACTURING STRAIN SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a strain sensor capable of being inexpensively prepared with a simple structure and easily visually recognizing deformation of an object.;SOLUTION: A strain sensor which is installed at an object and detects deformation of the object includes: a frame member which is installed at an object while including a first frame and a second frame connected to the first frame in a dividable manner; a sensor member having a first fixing part fixed to the first frame, a second fixing part fixed to the second frame, and a fracture part which is fractured when stress is applied by deformation of the object arranged between the first fixing part and the second fixing part; and a sensor film whose appearance changes when installed on the surface of the sensor member and the fracture part is fractured.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
