According to foreign media reports, with the sudden outbreak of the new crown virus, wearing masks has become a daily norm of behavior around the world, but this has also made it more and more difficult for us to listen to other people's voices and understand their expressions. Is the person wearing the mask smiling at me or making faces? These are difficult to judge.

Now, researchers from the Swiss Federal Institute of Technology Lausanne (EPFL) and the Swiss Federal Laboratory of Materials Science and Technology (Empa) have come up with a way to solve these problems, that is, to study breathable and transparent masks. Soon, you will be able to see the entire face of others through the mask!

Since the outbreak of the new crown epidemic at the beginning of the year caused a shortage of masks, and now they are frustrated because they cannot fully express their emotions when wearing masks, the work of finding the perfect mask continues.

Even thin masks may be uncomfortable to wear, especially after wearing them for a few hours, but the biggest challenge recently is to find a way to make them look less rigid and impersonal. In the past few months, medical staff have been trying hard to comfort patients or show concern while wearing masks, but to no avail.

The researchers named their invention HelloMasks, which is a mask made from organic biomass-based materials. They are not only breathable, but also recyclable and biodegradable. The research team also used a process called electrospinning, which uses electrical charges to create ultra-thin silk threads. This thread allows particles to pass through, but still manages to block the invasion of viruses and bacteria.

The research team is currently working hard to find a suitable manufacturing process to mass-produce new masks and is optimistic that they will be available in early 2021. The first people to use this mask will be medical staff and health care workers. (Little)
