AI 'electronic nose' sends smells over the internet and recreates them at the other end
Researchers at Ohio State University and China's Zhejiang Laboratory describe Scentronic in Science Advances: a system that recognises a smell with gas sensors and reproduces it remotely through a wristband or necklace that sprays fragrance. It is a lab prototype: for now it knows five smells, and in tests volunteers correctly identified the recreated smell 73% of the time.
