CHICAGO (WBBM NEWSRADIO) – A new smart sensor has been developed at Northwestern University that measures how well a mask fits a person's face.
FaceBit is sort of like a Fitbit and also measures heart rate and respiration. It’s the size of a quarter and attaches to a mask with a magnet.
The Chicago Tribune reported the co-developer, Josiah Hester, is an assistant professor of computer science, computer and electrical engineering at Northwestern’s McCormick School of Engineering.
Hester said the device detects how well a mask fits by measuring the change in resistance to the wearer’s breathing.
“We know mask fit is a big industry problem, but now it’s much more important to the general population,” Hester said.
Clinical studies are needed before mass production.
