its internal mechanism , not yet disclosed
any way read this The inspiration for the Aromascan machine came from a biochemist, Krishna Persaud, who set out in 1984 to create a model of the human nose. This highly sophisticated organ has 30 different types of sensors, with millions of sensors working in parallel. Each sensor can absorb a range of smell molecules on to its surface producing an overlapping response. The information from each sensor is fed to the olfactory bulb, which merges it and produces a pattern of the smell molecules that have been absorbed. It then refers the pattern to the brain, which checks it against its smell memory and says, in effect: 'Yes. I have smelt that before. It's a rose.' The basis of the Aromascan instrument is a range of conducting polymers, which, like the human sensors, trap smell molecules in their surface structure. This alters the polymer's ability to conduct electricity, and the resulting alteration in signal can be analysed to produce the electronic signature of each smell.This is then matched against a database of smells. The device can be set up to make fine distinctions - for example between Mysore and Brazilian roasts of coffee beans - or for simpler tasks, such as determining whether food is fresh or stale. The Aromascan instrument can be plugged into any personal computer. The software that analyses the data is a neural network, which learns to identify Brazilian coffee beans or whatever by being exposed to several samples of the bean and building up a database of smells in the same way as the brain.Mr Persaud found the first smell-absorbing polymer through a chance reference in a scientific paper. Since he joined forces with Peter Payne at Umist in 1986, however, a library of 50 polymers has been developed and patented. Professor Payne has become technical director of Aromascan digitising smells, creating the first electronic nose to equal the power of the human organ. Smells can now be faxed or transmitted by computer, an advance that will transform quality control by allowing food companies, perfume houses or drinks manufacturers to assess freshness, aroma and suitability of ingredients well before they are delivered to the factory. The development provides the first objective measure of smells, and can monitor the whiff from pig farms, sewage works or chemical factories. The equipment can also be used to detect fires and to monitor wound healing.Users of the technology, developed at the University of Manchester Institute of Science and Technology (Umist), include Coca-Cola, Ford, the European Space Agency, Whitbread, the Brewing Research Institute, water companies, a Japanese grain processing company and the Food Research Association.The company, Aromascan, was spun out of the university in March, and it is planning a full stock market listing later this year.

However, the current information technology is still unable to break the sense of smell, taste and touch, to smell it, to break through the technical bottleneck of this sensory organ is that we must first understand how humans can "smell" flavor, the key is in the air particles , passed to his nose inside and then smell the taste, so the sense of smell digital equipment, is to do to receive particle data, and bring them to digital and digital sense of smell should also be able to taste the particles derive from the information
Read Some industrial Disclose about Digital Smell Human beings are equipped with visual, hearing, smell, taste and ability to touch the five senses through the visual and auditory communication can be more than 55% of the message to the other, and still there were still 45% of the information is provided by the human taste, smell and touch afford. If human beings can "five sense" together to achieve real-time transmission to achieve "virtual reality" It is just how exciting things. Imagine you are watching the war films, the taste of smoke, bullets whistling pass by the sound ... ... as if you are a brave warrior in the battlefield on the gallop. Unfortunately, now you can just seated to watch the kind of smoke flavor can only rely on your imagination to complete. In order to achieve an extension of the human sense of smell, national research institutes are working on the spread of odors. Toyota exhibition hall in Tokyo, there is a small movie theater, where the smell and movie images with real-time passed to the gallery audience. Example, the actor and actress movie pass by, the kind of women's fragrance will also be immediately passed to the audience. Although this is not part of communication transmission, but the attempt to pass on the way in terms of smell is greatly improved. Have to achieve in the communication transfer images, sounds and smells of the simultaneous transmission more difficult. Through the three primary colors of light theory can reproduce almost all the colors out of realization of image transmission, while the sense of smell may be far from the constituent elements of information, not so simple. This requires odor sensors and odor synthesis technology. First felt by the smell the smell of sensor digitization of the data transmitted via the Internet, the recipient and through scent synthesizer will be to restore the odor out. Japan's Shiseido company is developing a perfume scent through the network transmission devices. It required the user through the computer to confirm the smell, and then specify the specific device emitting a smell. France Telecom is also studying the transmission through the network odor research. Need to connect your computer already contains a variety of scented "aroma generator", a user clicks on the site shown on perfume samples, will receive one of the sample information, then can use the "aroma generator" smell the smell of. The nation's largest computer products exhibition "COMDEX" scent transfer samples on display there. This is called "iSmell" Synthesis of smell a bit like a shark fin devices, single-shape is very special, it built a variety of odor sources, cassette, by the composition of a variety of odor to achieve a variety of flavor, as the combination of the three primary colors of light theory to achieve the same odor combination. If the human sense of smell can be extended to the network, it would be very meaningful. For example, in class looking Herbarium, the smell of plant names and learning together will greatly enhance the learning efficiency; in the hospital early in the evenings the smell of different distributed to regain up to the long-term hospitalized patients, but also to achieve medical fragrance therapy; in cosmetics advertising, also allows customers a variety of real-feel the flavor; in the game, the battlefield, the smell of smoke will greatly stimulate the game realism
