Project Description

Progress in sensor technologies and their applications has become a key ingredient for a sustainable development of today’s society. Gas sensors, in particular, are essential to address some of the major challenges, such as air quality in urban areas and their effect on human health, as well as monitoring, predicting and reducing environmental impacts due to air pollutants and greenhouse gases.  In this respect, mid-infrared (mid-IR) optical absorption techniques offer the possibility to realize highly sensitive detection of gases, which have inherently low molecular densities compared to liquids or solids.
