Northwestern University engineers have developed a new smart sensor platform for face masks that they are calling a “Fitbit for the face.”
Dubbed “FaceBit,” the lightweight, quarter-sized sensor uses a tiny magnet to attach to any N95, cloth or surgical face mask.
Not only can it sense the user’s real-time respiration rate, heart rate and mask wear time, it also may be able to replace cumbersome tests by measuring mask fit. All this information is then wirelessly transmitted to a smartphone app, which contains a dashboard for real-time health monitoring. The app can immediately alert the user when issues—such as elevated heart rate or a leak in the mask—unexpectedly arise. The physiological data also could be used to predict fatigue,...
