16 May 2008Novel FBG-based sensor configuration for H2 leak detection in air
The explosion risk linked to the use of hydrogen (H2) as combustible requires low-cost and efficient sensors. We present
a multipoint in-fiber sensor capable of H2 leak detection as low as 1% concentration in air with a response time smaller
than a few seconds. Our solution utilizes uniform fiber Bragg gratings (FBGs) surrounded by a catalytic sensitive layer
made of a ceramic doped with a noble metal. In the presence of H2 in air, the sensitive layer undergoes an exothermic
reaction and elevates the temperature around the FBGs. The sensor interrogation technique is based on the monitoring of
the resonant wavelength shift. In this paper, the performances of the sensor are also discussed.
