  • Abstract
    We have proposed and developed a new gas sensor using the change in the permeability of iron oxide nanowires. α-Fe2O3 nanowires are synthesized by the simple annealing of Fe bulks or films at 375°C in air. When the surface of α-Fe2O3 nanowires is changed by a reductive gas into α-Fe2O3 or Fe3O4, the permeability of the nanowires increases. Our sensor is based on the change in the permeability of the nanowires.
