Nb thin films were fabricated by magnetron sputtering and their hydrogenation behavior was investigated by electrical resistance measurements. A clear and reproducible resistance change was observed under hydrogen exposure as low as 10 ppm. The results indicate a high sensitivity of Nb thin films to trace hydrogen.
