Scientists have created a gas analyzer – ‘electronic nose’ that is able to assess the quality of the food, cosmetic, and medical products, to diagnose diseases by evaluating exhaled gases, and even detect explosives and drugs. The device analyzes a gas mixture using semiconductor sensors.
“Smell is determined by a combination of existing gases in the atmosphere. It is found that the conductivity of the semiconductor probe changes during sedimentation of the gas molecules from the atmosphere. This allows determining their presence,” says Timur Muksunov. “During manufacture the sensor can be customized to react well to some gases, and react badly to the others.”
It is impossible...
