Intel's Chip Learns to Sniff for Hazardous Chemicals


Your substances

Researchers at Intel Labs and Cornell University have utilized an unusual “neuromorphic chip” to quickly learn the signature smell of ten different hazardous chemicals and spot their presence quicker than ever before. The Loihi chip, as it is called, mimics how our brains classify and identify unique smells that our noses detect, retaining a memory of a particular chemical after only a single exposure to its smell. Existing technologies that perform similar feats require hundreds or thousands of exposures to a chemical before finally learning to identify it consistently.
