An artificial olfactory system (or simply put, an electronic nose) represents an interesting tool for various applications such as food quality control, identification of noxious gases and compounds in industrial sites and biomedicine. This type of system can also be useful as a diagnostic tool for space applications. The device could also be used on board the ISS for the detection of stagnation states, where the air circulation is limited and where carbon dioxide or other gases can be present at high concentration or where mould could grow.
