In this article, investigative study for measuring electric current using temperature sensitivity of fiber Bragg grating (FBG) is discussed. An FBG is kept inside a nichrome coil, which was pre-calibrated with respect to current and temperature by applying known value of current and measuring corresponding temperature. Two types of setups were used for the experiment: with and without housing. We found that the results were quite consistent and stable with the housing setup. The proposed current sensor has shown good response, repeatability, and very low hysteresis.
