A method for sensing hydrogen includes the use of a transduction device with a sensing layer, and means for measuring a mass and/or conductivity change caused by an interaction of a gas with the sensing layer to provide a measure of an amount of hydrogen in the gas. The sensing layer includes polyaniline nanofiber material.
Keywords: sensor, nanofiber, polyaniline
