Dr Justyna Jońca from the Faculty of Environmental Engineering at the Wrocław University of Technology is working on creating an “electronic nose” – a device that can help detect the sources of unpleasant odors and monitor their level in the environment. The three-year SENSODOR project is funded by a grant under the Marie Skłodowska-Curie Program.

The electronic nose consists primarily of a sensor matrix, and the heart of each of them is the so-called sensitive layer which can be made of semiconductor metal polymers or oxides. The signals collected from the matrix will create a so-called scent imprint – just like a human fingerprint as each fragrance mixture has its own unique pattern.

The samples will also be analyzed by a panel of human noses. The results of both measurements will be entered into a computer that through machine learning algorithms, will finally be able to determine the concentration and intensity of the smell of an unknown sample.
