Almost three years ago, many people lost their sense of taste and smell due to COVID-19. Some of those who recovered lost
Viruses have been “cutting off the sense of smell” for a long time, they writescientists. Olfactory dysfunction can also occur due to aging and brain injury, and there are not many treatment options. The authors of the development have been studying the problem since the 80s, but amid the pandemic, they managed to attract more investors to the study.
The device now resembles a cochlear implant in function and appearance.
A cochlear implant is a medical device.(prosthesis) that acts directly on the auditory nerve and makes it possible to compensate for hearing loss in some patients with severe or severe sensorineural hearing loss.
The implanted implant converts sound vibrationsinto electrical impulses, which are then transmitted through the auditory nerve, due to which it replaces hair cells that are inoperative for any reason.
In turn, the bionic nose works likeway. The glasses have a special sensor. He detects a scent. A special transmitter sends a specific signal to a stimulator implanted in the brain.

The anatomical diagram above shows a three-layera structure with olfactory receptors at the bottom where they bind to odor molecules, a layer of bone in the middle, and a yellow figure representing the olfactory bulb at the top. Olfactory receptor cells are distinguished by long processes that extend upward through the bone to the olfactory bulb. Odor molecules entering the nose bind to olfactory receptor cells, which send signals through the cribriform plate bone to the olfactory bulb. From there the signals are sent to the brain.
