Transparent medical mask, without fear of viruses, showing the charm of a smile

Since the outbreak of the epidemic, people have gradually become accustomed to the days of wearing masks. When the virus was isolated, our expressions were also isolated behind the masks. And for some special groups, such as deaf-mute people, they often need to rely on a combination of sign language and lip language to communicate. The use of masks can make communication and understanding difficult. Is it possible to develop a transparent anti-virus mask to isolate the virus without isolating our friendly expressions?

In fact, since the Ebola virus spread in Africa in 2015, Klaus Sch?nenberger, one of the founders of the startup Hmcare (also the head of the EssentialTech Center at the Federal Institute of Technology in Lausanne, Switzerland) saw such a demand, and another The founder Diane Baatard also had the same idea as Klaus when he worked at the Children's Hospital.

The encouragement of a doctor`s smile on the patient often has a very positive therapeutic effect. However, many transparent masks only replace part of the fabric with transparent materials, which can not meet the requirements of good virus protection and often fog up. As a result, Klaus Sch?nenberger, Diane Baatard, Thierry Pelet (Hmcare CEO) and Sacha Pierre Sidjanski. jointly initiated the transparent mask research and development project.
After two years, the Empa Material Science Laboratory in Switzerland and the EssentialTech Center of the Federal Institute of Technology in Lausanne worked together to find a material combination that met the requirements for transparency, resistance and porosity, and developed a completely transparent medical surgical mask. This kind of mask is called HelloMasks. It is made of 99% biomass-derived materials. It is made into a film by nanoelectrospinning technology. There are many tiny gaps in the fiber structure, which has good air permeability and can isolate viruses and bacteria. It also has a good anti-fog effect. And as a disposable mask, it is almost completely biodegradable.
