Abstract
Gas sensor, comprising: a substrate of semiconductor material; a first working electrode on the substrate; a second working electrode on the substrate, at a distance from the first working electrode; an interconnection layer extending in electrical contact with the first and the second working electrode, configured to change its conductivity when reacting with gas species to be detected. The interconnection layer is of titanium oxide, has a porosity between 40% and 60% in volume and is formed by a plurality of meso-pores having at least one dimension in the range 6-30 nm connected to nano-pores having at least one respective dimension in the range 1-5 nm.
