Nice idea if usefully effective and accurate.
Smart Mask Tracks Respiratory Sounds for Disease Identification
City University of Hong Kong
November 2, 2022
A smart face mask developed by researchers at the City University of Hong Kong (CityU) can detect and recognize respiratory sounds using an integrated, high-sensitivity soundwave sensor and machine learning algorithms. The ultra-thin, lightweight sensor, comprised of carbon nanotube and polydimethylsiloxane materials, can be used with both rigid masks and deformable non-woven fabric masks. The researchers found the acoustic wave sensor can measure both static and dynamic pressure and sense air movement, including directional flow and vibration. Said CityU's Wang Jianping, "Advanced artificial intelligence technology enables the integrated mask to recognize different coughing and breathing patterns automatically, indicating its potential use to diagnose respiratory-related diseases in the future." ...
