Abstract

In this paper I report the preparation and characterisation of an improved hydrogen gas sensor with a better sensitivity, using an amorphous thin WO₃ film covered Pd film. Using a very sensitive optical sensing technique, such as the interference phenomena and a special configuration of the sensing structure were obtained interested results showing the influence of H₂ gas on the optical sensor response. I present the design and results for an interferometric fiber optic hydrogen gas sensor, the Intrinsic Fabry-Perot Interferometer (IFPI), which uses the changing properties of layered interferometric sensing structure Pd/WO₃ to detect hydrogen gas concentrations in the 500 - 2,000 ppm in synthetic dry air, with the working temperature at 80 °C in the presence of CH₄.
