Tokyo-based Aroma Bit showcases their odor imaging sensor technology, they claim to be able to make a unique sensor to analyze the subjective matter of smell, rather than simply to analyze the contents of the gas. The setup on display shows how a bottle opened nearby produces a digital odor signature on the screen. The sensor prototype is mounted on an SD card. The device learns about the signature of each smell it encounters, becoming smarter.
