Research Abstract

An evanescent-wave absorption type fiber-optic hydrogen gas sensor for distributed leakage monitoring was developed. A platinum-supported tungsten trioxide(Pt/WO_3) thin film as hydrogen sensitive material was successfully immobilized on periphery of bismuth based optical fiber by sol-gel method. In the presence of hydrogen, sharp sensor response based on the change in evanescent-wave absorption of sensing clad region was observed. Furthermore, reproducibility of the sensor with repeated exposure to hydrogen gas was good. Finally, multipoint sensing performance was demonstrated. These results indicate that the proposed sensor is promising for a low-cost and distributed leakage monitoring.
