EPFL of the Federal Institute of Technology in Lausanne, Switzerland and Empa of the Swiss Institute of Materials Testing, have jointly created a medical mask with a transparent yet breathable fabric-like function. Since we are considering disposable rather than reuse, 99% of raw materials use biodegradable products made from biomass resources.
According to EPFL, the fiber gap is 100 nanometers as before. Air can pass while the virus cannot pass. It is a breakthrough invention, but it is said that the development moment was at the time of Ebola in 2015. However, when it was completed in five years after repeated research on how to mass-produce without polluting the environment, the Corona 19 incident was right.
However, it is not released immediately. It has already established a startup and raised the fund for 1 million Swiss francs, but it is expected to start production in the future, so it is said that it will appear in the market by the beginning of 2021. The masks that have been released so far have the disadvantage of not being able to communicate smoothly because their facial expressions are not visible. However, if this hello mask is spread to the general public, it may be used in various fields such as hospitality. Related information can be found here .
