According to foreign media reports, when the new coronavirus first appeared, the US CDC recommended that people make their own masks due to insufficient supply of masks. So a fashion designer named Chelsea Klukas wanted to design a personalized mask. Klukas is a designer, and she wants to make the mask more interesting. In an interview, she said: “I have enough materials on hand, so I found a DIY video on YouTube to learn how to make a mask.” The most distinctive part of the mask she designed is that there is an LED matrix screen on the mask, and the wearer can also customize the display content of the screen. Through the supporting mobile phone application, this LED screen can display patterns and text, etc. content. This LED screen can be drawn out, which means the mask can be cleaned. It should be noted that if you want your mask to display personalized content, the wearer needs to charge it regularly, just like using electronic devices such as mobile phones. Before the new coronavirus disappears, masks will continue to play the role of daily necessities for people to travel. And this mask that will display patterns and text has another function: always remind others to keep enough social distance with themselves. For example, you can make the LED screen display some prompt words, such as “please stay away from me” or “please keep one meter away” and so on.
