The computer interface in the nose can convert into super detectors

So far, the wrapping has been tested in the mice, with the release of dogs at a later time, says Lafila. In a trial video that is displayed exclusively by WIRE, the world of Canaey uses a stick to capture an air sample of four different Petri dishes, each containing a different smell. The stick is released and the scent molecules are sent via a tube to a pod that includes mice equipped with an interface to determine the nose. After a few seconds of the scent of the animal, the smell of the smell, the smell information is sent to a phone sitting over the pod. The mobile phone application displays the name of the compound from which the smell of the animal is emitted, in addition to the degree of quality that takes into account the accuracy and concentration of the molecules.

Currently, the initial model of the rat in Canaery can discover premeditated and powdered burning accelerators that are not smoked in ammunition, as well as methamphetamine, cocaine and fentianil.

In mammals, the nose and the brain work together to discover odors. When the smell particles enter the gills, they are linked to the shelter’s receptors. Humans have about 450 types of olfactory receptors, while dogs have twice a large number of them. Each smell stimulates different groups of receptors, which produces a unique electrical signal. This signal is sent to the sham lamp to be treated. Lavella resembles the surface of the shampain to the examination plate. When the smell comes, the squares illuminate the walking plate in a specific style.

Canaery uses AI to learn about these patterns and link them to odors. After transplantation, scientists expose the animal to a scent to train artificial intelligence models. Lafila says the program can be trained in about three sessions. During these sessions, scientists offer more than twenty samples of the same smell to the animal. Later, the animal is scent again to verify the authenticity of artificial intelligence models.

The current row implanted in the experimental mice contains 128 poles capture nervous signals from the sham lamp. Researchers at the Lawrence Levermore National Laboratory are working on a new array with 767 poles to capture more information. “The next generation device will allow us to do more in this field against the scents of the complex background and confusing fumes in the air,” says Lafeella.

Deciphering the smell is not a new endeavor by any means. The researchers were working on “Electronic” technology To detect odors over the past forty years. These devices use chemical sensors to convert the scent molecules into electrical signals, which are then analyzed by the patterns recognition system to determine the source of the smell. But these devices historically managed to discover only a small group of odors.

“Animals can do things that we cannot obtain from the current sensors, so this is a smart way to overcome this problem,” says Joel, a Shamli researcher at the Monel Chemistry Center, a non -profit research institute in Philadelphia.

Canaery, which is placed on the surface of the animal’s sham, is thinner than a piece of tissue and a quarter of the American mail seal size.
