Created “electronic nose” that can distinguish up to 10 odors

Nobody argues with the fact that the human senses are incredibly accurate instruments for the transfer of the variety of sound, visual and tactile sensations, with which we have the opportunity to learn this world. Wanting a bit to compete with nature in the skill of generating funds for the knowledge of the olfactory impressions, an engineer from Intel have invented a unique device, able to perceive up to 10 different odors and to successfully distinguish them from each other. What is the benefit of modern science can bring unusual invention?

Nabil Imam — Creator of the “electronic nose”

How to return the sense of smell?

Invented by a specialist known Intel device is able to detect ten different odors, thus simulating the work of the olfactory system of the human body, according to the portal It is known that even if the room is deep, rich flavors, the device is successfully allocated programmed him earlier odors, keeping “memories” of them in a kind of likeness of its own network of nerve cells.

Although the device in the technique of smell is still very far from human, able to perceive to a trillion (!) different smells and aromas, “electronic nose” is a real breakthrough, which will find its application not only in creating alarm systems to check the leakage of a chemical substance, but even with the creation of artificial intelligence. Agree, it would be nice one day to have a debate with a robot about the smell of just-baked cake or, say, to discuss with him the smell of the forest after rain. Such a change could significantly to“humanize” the robot of the new generation, giving it more of a similarity with the person.

A unique system has learned to recognize ten smells

Although currently there are a large number of gas sensors, capable of detecting dangerous concentration of harmful gases in the air, they are all set only to certain substances. So, they are not able to learn to recognize new odors, which greatly limits their ability during operation. In order to overcome this drawback, the scientists decided to peep the decision in nature to mimic the device of the olfactory system of animals.

How does the human nose?

Maybe you know that the human nose has more than 450 different olfactory receptors. The substance, when applied to specific receptors, activates them, and the result of this action the information gets into the brain, which analyzes and stores the data about the new smell. Remembering it, the brain then activates the stored information just in the moment when we will feel the same smell next time.

The receptor is sensitive to external influence of nerve ending or cell that turns irritation into nerve impulses and sends to the brain.

Most interesting is that responsible for the reproduction of an odor part of the brain is activated even when we try to imagine one or the other memorized the scent. However, in this case the whole system works only partially, and therefore, reproduced us by the aromas of does not turn out to be so vivid as real sensation from the smell.

Perhaps in the future an “artificial nose” will return to some sense of smell. If you suddenly ceased to feel smells — alerted, because it is one of the symptoms of coronavirus

It is reported that by scientists from Intel, the device simulates such a simple but ingenious mechanism for storage and playback of flavors. The researchers believe that the term “artificial nose” could get a lot of useful applications, including in the diagnosis of some dangerous diseases. In order to achieve a similar result, scientists still need to conduct additional experiments that will help to make the device more perfect.

It’s hard not to agree that the achievements of modern equipment is gradually bring us closer to the future, which dreamed of fiction. Earlier already talked about the fact that artificial intelligence has learned to recognize people even in their ability to dance.
