Abstract
This study is a short overview on air pollution, its definition, history, and adverse effects on health, environment, and economy, with a particular emphasis on indoor air quality. We demonstrate that gas sensors based on silicon carbide field effect transistor (SiC-FET) technology are suitable for indoor air quality applications due to their high sensitivity, long-term stability, and robustness. Enhancement of selectivity can be reached through the optimization of the sensing layer (gate contact) in combination with smart operation and multivariate statistical methods for data analysis. Formaldehyde, naphthalene, and benzene, belonging to the class of hazardous volatile organic compounds (VOCs), are our target gases at the low parts per billion concentration level.
