Abstract
ZnO tetrapods were synthesized by an "environmentally green" microwave evaporation of Zn powder in air atmosphere, without any use of organic solvents or precursors. The tetrapods were characterized by X-ray diffractometry and Field Emission-Scanning Electron Microscopy. The ZnO powder was then deposited onto a commercial alumina substrate with interdigitated platinum electrodes and the sensitivity towards humidity was investigated at room temperature. Results showed a significant response from 30% relative humidity values and that the sensors were insensitive to N2O and methane.
