Zinc Oxide (ZnO) nanostructures have been obtained by vapour phase growth. Tetrapods have been grown on a large scale, in a reproducible way and separated from the other possible ZnO nano-morphologies, by the optimization of growth parameters. The deposition of these nanostructures on an alumina substrate with contacts and heater, allowed us to realize a low-cost oriented gas sensor. The obtained ZnO tetrapods-based gas sensor prototypes have been tested with different gases.
