Japanese startup Donut Robotics designs smart masks that connect to phones via bluetooth

 
A new app would say if you’ve crossed paths with someone who is infected

The face mask, called 'C-Mask,' can be worn over regular, fabric-based masks. It connects to an app via Bluetooth, enabling it to transcribe speech to text messages, which are then sent via the user’s smartphone. It can also translate from Japanese into eight other languages and amplify the user’s voice, in case they are not heard through the mask.
