Scientists Artificially Recreate Smells Using Olfactory Display
Tokyo Tech News (Japan), April 1, 2022
Researchers at Japan's Tokyo Institute of Technology have developed technology that can artificially replicate diverse scents by combining multiple odor components. The researchers defined 185 essential oils using mass spectrometry, then extracted 20 corresponding basis vectors via multidimensional data analysis. They produced various smells by mixing odor components corresponding to these basis vectors, and were able to emulate a variety of scents by adjusting the composition of odor elements. The team also used an olfactory display to generate scents instantly in the gaseous phase from 20 odor components. In a sensory test, people using the display were presented with seven typical essential oils derived from the 185 essential oils; the test subjects reported no significant difference between the original and reproduced smells. ...
