Description du projet
Des capteurs de gaz intelligents de petite taille pour lutter contre le changement climatique
Le changement climatique augmente le risque de phénomènes météorologiques extrêmes et désastreux. Il est urgent de trouver des solutions susceptibles d’améliorer notre adaptation au changement climatique ainsi que son l’atténuation. Les gaz à effet de serre, notamment le dioxyde de carbone, l’oxyde nitreux et le méthane, sont parmi les principaux responsables du réchauffement planétaire. Les équipements de surveillance des émissions sont généralement coûteux, encombrants et complexes. Le projet NEOGAS, financé par l’UE, développera de nouveaux capteurs de gaz adaptés à l’internet des objets (IdO) et fabriqués à partir de matériaux à structure métallo-organique. Les dispositifs développés seront testés pour la détection des gaz à effet de serre et seront comparés à des stations de référence environnementales. Capable de fournir plusieurs lectures, cette technologie gagnera en efficacité.
Objectif
The emission of greenhouse gases (GHGs), especially of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), is the major source of global warming and climate change. To monitor their emissions, one can find in the market highly sensitive and selective, complex, bulky and expensive instruments, used as reference measuring systems, which can only be installed in few specific locations. For an accurate spatial control of these emissions, however, large number of sensing systems need to be installed and connected, benefitting from Internet of Things (IoT) and providing the required ubiquity. Usually these devices do not need to meet the sensitivity level of the reference instruments.
The present project addresses the development, fabrication and testing of gas sensors, suitable for IoT, made from advanced metal organic frameworks (MOFs) materials. These gas sensors will be multivariable devices, providing the simultaneous readout of the change of electrical and optical properties when exposed to gaseous species, in opposition to standard gas sensing devices, that deliver one single readout. This innovative approach is expected to present advantages over the standard devices, especially in terms of miniaturization, compactness and selectivity, as they are integrated nanoelectronic noses. The developed devices will be tested towards GHGs and will be benchmarked against environmental reference stations.
