“Smart” mask auto-adjusts its breathability in response to conditions

As most of us have noticed over the past couple of years, face masks can sometimes be a hindrance – necessary though they are. An experimental new mask, though, automatically becomes easier to breathe through when maximum air filtration isn’t required….
