The device uses ballistocardiography, in other words a sensor detects smallbody to measure heart rate. One detects respiratory rate. Finally, a third sensor analyzes changes in and thus locates the leaks of . It can then alert the user that the mask is ill-fitting or defective, and notify them when it is time to .
The FaceBit is powered by a small button cell battery that provides 11 days of battery life. However, the device can work for weeks thanks to tiny . The researchers hope that other people will be able to build, validate and improve the FaceBit.electric harvesters , thermal and .
