New electronic nose claims up to 90% accuracy


Israeli scientists backed with EU funding have developed an electronic nose that can accurately predict whether a scent will be pleasant or unpleasant to humans.

A European Commission briefing note said scientists from Israel’s Weizmann Institute of Science and the Edith Wolfson Medical Centre found their device's odour pleasantness ratings were more than 80% similar to human control assessments. It added: “The eNose's ratings were also more than 90% accurate at discriminating between categorically pleasant or unpleasant odours.”

Published in the journal Public Library of Science (PLoS) Computational Biology, “the results could potentially lead to new methods for odour screening and environmental monitoring,” said the Commission note.
