Japanese electronics giant Sony has developed a device to measure an individual's sense of smell. The company hopes it will eventually be used at hospitals as olfactory measurement could help with the early detection of dementia.
Sony says the equipment can produce 40 different smells. It instantly emits a scent when the operator selects one from a dedicated app. Test subjects also use the app to indicate what they think the smell is.
