The British designer has developed an antibacterial face mask at home with 16 LED lamps that respond to words and a smile.

The main problem with wearing masks during a coronavirus pandemic is that they do not allow people to see each other’s faces, and this can cause discomfort during communication. British designer Tyler Gleiel has solved this problem.

The electronic devices in the mask do not glow chaotically, but respond to human words and smiles: the designer used a primitive Arduino Nano processor and a microphone that transmit signals to the LED matrix. This mask requires a 9-volt battery and a bit of insulating tape, so the device is not very compact.
