Researchers from the Massachusetts Institute of Technology in the United States have created a battery-powered muzzle with a copper net that reaches 194°F (90°C) that kills the Coronavirus in the air.
And an electric face mask can kill coronavirus particles by passing the air you breathe through this mesh.
According to the British newspaper “Daily Mail”, this concept makes the hot metal filter surrounded by insulating neoprene to allow it to be worn.
The researchers said that the device that works if the battery will be marketed probably the most expensive of the cloth mask or surgical mask or ventilator device N 95.
But a hot mask would be ideal for situations where the risk of exposure to the virus is high, such as in a healthcare environment or on crowded public transport.
Nor will you need to dispose of it or sterilize it after using it, as researchers who applied for a patent for the mask design began building prototypes for physical testing.
Leader of the research paper and chemical engineer Samuel Faucher explained that the vast majority of masks today work by filtering or filtering particles by size or electrical charge.
The senior researcher and his colleague, chemical engineer Michael Strano, added: “This is a completely new concept of the mask in that it does not basically prevent the virus, but rather allows it to pass through the mask, slowing it down and disrupting it.”
The researchers created mathematical models to determine the optimum temperature range the network would need to reach in order to thermally inactivate the coronavirus particles when inhaled inside or outside the mask.
They determined that a temperature of about 194 degrees Fahrenheit ( 90 degrees Celsius) could reduce the concentration of the virus in the air by between one thousand and one million, depending on the size of the mask itself.
This temperature can be achieved by running an electric current through the network, and it is made of copper wire with a thickness of 0.1 millimeters, and take power from a 9-volt battery, which should be able to run the mask for a few hours at a time.
