As the wearing of masks has become a new global standard for epidemic prevention, people are beginning to feel the inconveniences of traditional masks. For this reason, Swiss scientists have proposed a new "transparent mask" design, which has breathable and virus-blocking effects while being incomplete. Covering the wearer’s face is expected to be available in early 2021 at the earliest.
The current masks have been invented and used for nearly a hundred years, but as everyone must wear masks in public, some problems have also surfaced. The design of covering the face not only affects the accuracy of face and voice recognition, but also It is difficult for people to convey emotional support through facial expressions, and it is also more difficult for hearing impaired people to read lip language.

In order to solve this problem in the past few months, some prototype designs of transparent masks have been circulated on the Internet, but many of them involve replacing part of the mask with a transparent plastic panel. This approach not only reduces air permeability, but also makes The mask is fogged due to the wearer's breath, thereby invalidating the original transparent intention.

Researchers at the Swiss Federal Institute of Technology Lausanne (EPFL) and the Swiss Federal Laboratory for Materials Science and Technology (Empa) have been developing better alternative products. After two years of research, they can be used to create a new transparent mask HelloMasks. The material was born.
Using a manufacturing process called electrospinning, the fiber spacing of HelloMasks masks is only 100 nanometers, which is the same as traditional medical masks. It allows air particles to pass through and can effectively block bacteria and viruses. At the same time, 99% of masks are based on Made of organic and biological materials, HelloMasks can also be recycled and biodegraded without causing environmental pollution problems.

HelloMasks is not just a research project. The research team has established a start-up company HMCARE, and is currently developing the manufacturing technology required for mass production of transparent masks. The team is quite optimistic about the development prospects of such masks, and believes that it will be available in early 2021 at the earliest and will be provided to medical professionals first. People, as output increases, it will eventually be available to the public.
