New sensor called FaceBit can tell if health mask fits properly and provide other data


Health care workers now must undergo cumbersome 20-minute tests to ensure proper mask fit. The test involves wearing a shield over the face, then spraying a sweet or bitter aerosol at the face and seeing if the worker can smell it. If so, the mask isn’t tight enough. — AP

FaceBit, as it is called, also measures heart rate and respiration, similar to the fitness wearable Fitbit, but with special attention to mask fit.
