Intel’s Neuromorphic Nose Learns Scents in Just One Sniff

Researchers at Intel and Cornell University report that they’ve made an electronic nose that can learn the scent of a chemical after just one exposure to it and then identify that scent even when it’s masked by others. The system is built around Intel’s neuromorphic research chip, Loihi and an array of 72 chemical sensors. Loihi was programmed to mimic the workings of neurons in the olfactory bulb, the part of the brain that distinguishes different smells. The system’s inventors say it could one day watch for hazardous substances in the air, sniff out hidden drugs or explosives, or aid in medical diagnoses.
