Created an “electronic nose” capable of distinguishing up to 10 odors

No one argues that the human sensesare incredibly accurate tools for conveying the whole variety of sound, visual and tactile sensations with which we have the opportunity to experience this world. Wanting to compete a little with nature in the skill of creating tools for cognition of olfactory impressions, an engineer from Intel invented a unique device that can perceive up to 10 different smells and successfully distinguish them from each other. What is the use of an unusual invention for modern science?

How to return the sense of smell?

Invented by a specialist from Intelthe device can recognize ten different odors, thus simulating the functioning of the olfactory system of the human body, reports It is known that even in the presence of strong distracting aromas in the room, the device successfully released the smells programmed to it earlier, storing the “memories” of them in a kind of semblance of its own network of nerve cells.

Although the device in the sense of smell is still veryfar from a person who is able to perceive up to a trillion (!) of various smells and aromas, the “electronic nose” is still a real breakthrough that can find its application not only in creating alarm systems for checking leaks of a particular chemical substance, but even in creating artificial intelligence. Agree, it would be nice to once discuss with the robot about the smell of a freshly baked cake or, say, discuss with it the aroma of the forest after rain. Such a trifle could significantly “humanize” a new generation robot, giving it more similarity to a person.

A unique system has learned to recognize ten odors

Although there is currently a largethe number of gas sensors capable of detecting a dangerous concentration of harmful gases in the air, all of them are configured only for certain substances. So, they are not able to learn to recognize new odors, which greatly limits their ability to operate. In order to overcome this significant drawback, scientists decided to spy a solution in nature by imitating the device of the olfactory system of animals.

How does a human nose work?

Perhaps you know that the human nose has more than 450 different olfactory receptors. A substance, reaching certain receptors,activates them, and the information obtained as a result of this action enters the brain, which analyzes and stores data about a new smell. Remembering it, the brain then activates the stored information just at the moment when we feel the same smell the next time.

Receptor - This is a nerve ending or a cell that is sensitive to external influences, which turns irritation into nerve impulses and transfers it to the brain.

The most interesting thing is that in charge ofthe reproduction of one smell or another part of the brain is included even when we try to imagine this or that remembered aroma. However, in this case, the entire system works only partially, which means that the aromas reproduced by us from memory do not turn out as bright as the real sensations from smells.

Perhaps in the future, “artificial nose” will return some people a sense of smell. If you suddenly stop smelling, beware, because this is one of the symptoms of coronavirus

It is reported that created by scientists from the companyThe Intel device imitates a similar simple but ingenious mechanism for reproducing and storing aromas. Researchers are confident that in the future, “artificial nose” could get many useful applications, including the diagnosis of some dangerous diseases. In order to achieve such a result, scientists still need to conduct additional experiments to help make the device more perfect.

It’s hard not to agree that achievementsmodern technology is gradually bringing us closer to the future that fantasists dreamed of. Previously, already talked about how artificial intelligence has learned to recognize people even by their dancing ability.
