The Norwegian University of Natural and Technical Sciences has presented an innovative “electronic nose”. It is capable of analyzing fruit and meat smells with high accuracy. The development is based on a single antenna emitting radio waves at different frequencies. The reflected signals help to determine the chemical composition of volatile organic compounds in the air, creating unique patterns for each odor. Despite using only one antenna, the device achieves 96.7% accuracy. The lead author of the study, Yu Dang, noted that the “antenna nose” is able to distinguish between isomers - substances with the same chemical formula but different molecular structure. The technology has already proven itself in determining the freshness of products such as fruit and meat. However, the developers see broader application prospects. Dang emphasized that volatile organic compounds could help diagnose diseases, similar to the way trained dogs do. However, unlike animals, the “electronic nose” does not require training and this makes its practical application more convenient and accessible.
