Ohio State University develops AI electronic nose and scent-release wearable device
Understand this story
A team at Ohio State University has developed an AI electronic nose and wearable scent-release system called Scentronic, which uses machine learning to classify scent data in real time and release the corresponding scent. The research was published in Science Advances. After training on five scents—coffee, beer, red wine, orange, and chocolate cake—in field tests, participants identified single scents with about 73% accuracy and paired scents with about 71% accuracy. The team has produced wristband-style and five-channel necklace-style prototypes, and next will explore integrating the device into everyday wearable accessories such as watches.

Researchers at The Ohio State University developed an AI e-nose paired with a wearable scent-release system called Scentronic, which uses machine learning to classify odor data in real time. Trained on five food scents (coffee, beer, red wine, orange and chocolate cake), the system let participants identify individual odors about 73% of the time and paired scents about 71% of the time. The prototype was built in wristband and necklace versions, and the team's next steps include testing integration into watches and smart jewelry.
