Abstract :
We enhanced the temperature sensitivity of a fibre Bragg grating sensor by attaching two metals with different expansion coefficients to it. The temperature sensitivity can be changed by varying the metal lengths. The proposed temperature sensor can be applicable as a high sensitivity temperature sensor
