Abstract: By semiconductor gas sensor array to feel all kinds of substances nature odor,we use the sensor array and the neural network software interface and conversion BP neural network algorithm for data processing and information fusion.On the basis of the multimedia transmission via the Internet or 3G mobile communication network,we will not use traditional methods of odor synthesis generator,to achieve the purpose of ultra-long-range olfactory transmission．It is posible to research ultrasonic direct conduction to the center of the human brain olfactory sensing mode,to achieve olfactory transmission direct transmission mode.Explore and experiment to prove the feasibility of the olfactory transmission on mobile phones(mobile terminal) and reproduction mechanism to elucidate the smell,will reveal the significance of machine olfactory law,will provide ideas to human sense of smell,taste,touch on worldwide Internet and mobile communication network conduction.
