The E-Nose Knows: AI Learns to Smell

Among the possible implications are restoring a sense of smell, and sniffing out potential health concerns

Researchers are developing e-noses, electronic systems that use AI to scrutinize aromas with high precision for diverse applications.
E-noses are being explored for medical diagnoses, such as detecting infections from breath, and for identifying hazardous compounds in environments.
The technology is also being applied to authenticate products, create new fragrances and monitor livestock health and emissions.
