Paper Abstract

We used a bimetallic strip to increase the sensitivity of a fiber Bragg grating temperature sensor. The temperatureinduced deflection of the strip strained the FBG sensor, increasing the Bragg wavelength shift in addition to the temperature-induced one. The total Bragg wavelength shift is about 4 times larger than that of the intrinsic FBG temperature sensor. With experiments in various conditions, the sensitivity characteristics according to the bimetal parameters were analyzed and the feasibility of the suggested sensor has been shown
