MOF coated coupled resonators as high performance indoor air quality sensors

Air pollution, outdoors as well as indoors, is a worldwide 'grand societal challenge'. There is currently considerable effort to develop small and low-cost air quality sensor systems, however current technology does not deliver reliable measurement data that is suitable for policy makers or scientists. We plan to change this by combining two innovative technologies: Prof Kraft’s group has worked on micromachined, coupled resonators that exhibit orders of magnitude higher sensitivity for gravimetric sensing. Prof. Ameloot’s group has developed innovative surface coatings using chemical vapor deposition of Metal-Organic-Frameworks (MOF). These materials have a high affinity for specific molecules through reversible interactions. A high-performance gas sensor can now be realized through a MOF-coated resonating structure and thus achieve high sensitivity, low cost, high specificity and continuous monitoring. As a demonstrator of this approach, we will focus on a gas sensor to detect formaldehyde.
