Professor Takeshi Yanagida and Associate Professor Yuta Tsuji (Faculty of Interdisciplinary Science and Engineering) achieved both robustness and sensing sensitivity in artificial olfactory sensors. They proposed a new sensor operating principle that intentionally utilizes Van der Waals forces between hydrophobic molecular scaffolds and hydrophilic solid surfaces, which were previously considered to have a small contribution.

This achievement is expected to contribute to "odor data science" and its industrial development. It is anticipated that long-term measurement of odor information will become possible.
