Lithuanian scientists of Kaunas University of Technology (KTU) and start-up Assero have introduced an innovative see-through mask. The mask prototype has already been recognised internationally, as it won second place in the Silicon Valley Innovation Competition.
The key innovation introduced by Lithuanians is a thin fibre of nanoparticles sandwiched between two transparent material mask layers.
“[The masks] are made of very small filaments that are 15–20 times smaller than a hair. They have pores, through which air can penetrate, but dirt and very small particles are effectively trapped,” said KTU professor Dainius Martuzevičius.
Pranas Šileika, head of Assero, who came up with the transparent mask idea, said that the product still needs to be tested and improved, with mass production planned for next year.
According to him, such masks will be relevant even if the coronavirus subsides, as “masks were needed even before the pandemic”.
“We need quality products that allow us to communicate and see other people's emotions,” Šileika said. “Based on the market's interest in our solution, I think we should reach a production capacity of several million within a couple of years.”
According to the KTU press release, the transparent mask works in the same way as conventional medical masks or respirators. Previously introduced transparent masks had major drawbacks, such as being dewy, uncomfortable to wear, or failing to provide the necessary protection, it added.
The KTU and Assero scientists hope to attract investors and start production development in the near future.
