Study On Fiber Bragg Grating Mechanical Practicing Hand Sensing Technology

Fiber Bragg grating (FBG) has a small size, light weight, distance transmission, anti-electromagnetic interference, corrosion resistance, passive, etc., it is becoming the focus of the sensing field of study, is often used to measure the stress/temperature and strain a new type of optical fiber sensors, its application will have a very broad prospects for development.The main contents of this article is to design a practical fiber Bragg grating strain sensors. Provide the necessary sensing support for post-manipulator or robot. Fiber Bragg grating as the object of study, and its sensing mechanism of cross-sensitivity and stress sensitizing analyzed in depth. Consider the actual application, focusing on the discourse Fiber Bragg Grating cross sensitivity, stress sensitivity programs and space force measurement.Papers around the use of fiber Bragg grating strain sensing commence. First introduced to the fiber Bragg grating is used for stress measurement technology and research status; followed by the fiber Bragg grating sensing principle, from the principle level, the FBG stress, the temperature cross-sensitivity mechanism, and proposed a new temperature compensation scheme; again by discusses the comparison of different stress sensitivity program, select the applicable sensitizer for the design of the sensor; examination of existing robot force sensors and fiber Bragg grating sensor design capable of measuring the space force. With the force simulation, and optimize the design.
