During the new crown epidemic, masks have become part of daily life, so a series of studies on masks have been put on the agenda. Researchers at Northwestern University have developed a "FaceBit" mask sensor that can track a wide range of health data from N95 masks.
According to reports, the "FaceBit" mask sensor can measure heart rate through the subtle head movements produced by blood pumping and can detect air leaks or wearing errors by looking for sudden drops in mask resistance.
In addition, these measurements can help the sensors detect a range of other conditions, such as heart and breathing data that can let users know when they're stressed and need to rest.
The sensor contains a battery and can be charged through breathing, heat, exercise and solar energy for up to 11 days.
FaceBit needs to pass clinical trials and other tests before it can be put into practical use. However, the researchers have released the project's code and hardware to the public to help others build and validate it.
