The Metal Oxide Semiconductors are chemical sensors, which have become mass-use for their large field of applications, their small size and their simple manufacturing. In addition, they have a high sensitivity so they can detect very low concentrations, operate in a wide temperature range and possess long durability. In particular, the system Cr2-xTixO3 is a solid solution with corundum structure (0.01 < x
