This project aims to develop novel materials (perovskites) as gas sensing elements. A second challenge will be to address gas selectivity, which could be a major breakthrough in sensor technology. At the end of this project, we aim to fabricate a prototype “nano” gas sensor, adaptable to smart/portable devices, which can be used to monitor the quality of breathing air in homes, cities. Such sensor can also be implemented in other sectors, such as in transportation, industry and agricultural production
