During the Corona virus pandemic, many people around the world used to wear face masks to protect themselves and others, and people with chronic respiratory problems used them to purify the air from harmful pollutants, but this does not mean that masks are always comfortable.
The researchers were able to ACS Nano From developing a respirator that dynamically adjusts pore size in response to changing conditions, such as exercise or air pollution levels, allowing the wearer to breathe easily and controlling the amount of air that escapes through them depending on usage variables and different levels of pollution.
And publish a site ACSDetails of this developed muzzle, as face masks protect against the spread of the virus that causes COVID-19They are also worn by people with respiratory problems to filter out harmful pollutants. However, in some circumstances, high levels of pollution are not required, such as when air pollution levels are low, or when someone is practicing outdoors alone which is generally considered a low-risk activity to spread COVID-19.
But current masks cannot adapt to changing conditions. Over time, trapped breathing and exhalation can create a sensation of heat, humidity, bad breath and discomfort, especially as more breath comes out during exercise.
The smart mask is made of micro-fibers with electrical properties that contain microscopic pores, and these pores can widen to allow a larger amount of air to enter or shrink to reduce the amount of air that passes through them, and experiments showed that the percentage of lost efficiency in air purification using this muzzle is not exceed 6%.
One of the advantages of this muzzle is that it wirelessly connects to an external computer that works with artificial intelligence techniques to measure the degree of air pollution and monitor any changes in the user’s breathing pattern so that he can adjust the specifications of the muzzle according to the user’s need and the surrounding pollution conditions.
