Abstract
At present, reported compensated sensor are lower strain transmission rate, or unable to test strain. At the same time, This paper presents a novel FBG strain sensor with a self-compensating function. It can not only implement strain testing, but also has a temperature-compensated function The results are as follows: this package was shown to have a high strain sensitivity of 1.5 pm/muepsiv and the temperature intensity of the compensated sensor of 1 pm/deg, which was decreased by 91.5%..
