Caption

Picture of an artificial olfactory sensor used for biometric authentication based on breath. The sensor is made of a 4x4 channel array for a total of 16 sensors. Each sensor detects a specific range of compounds found in human breath. The data is then processed by a neural network, which then determines the individual.
