American scientists have developed a facial FaceBit sensor to control the indicators of vital activity. This is reported on the University of Nurtusnn website.
The created sensor has a small size and embedded in a protective respirator type N95. The device holds on a magnetic mount and can be added to almost any suitable mask. FaceBit, named after the popular Fitbit FitBit series, has the ability to control the heart rate based on human breathing.
According to developers, heartbeat and respiration data can help prevent stress or exacerbation of respiratory diseases. The combined breathing-based device also allows you to determine the density of the fit of the mask to face.
The prototype created in the laboratory has a built-in battery, the device is charged by passing air through a special membrane. FaceBit is positioned as an inexpensive device for monitoring health indicators, the device can work on one battery charge up to 11 days.
The study states that FaceBit must pass clinical trials before shipping. However, scientists have published the source code of the project for all those wishing to create a similar accessory.
In May, scientists from the Institute of Chemistry of Max Planck Society Revealed the true efficacy of masks. According to the report, ordinary masks provide protection against penetration of viral particles by 30-70 percent, class N95 / FFP2 respirators – up to 95 percent.
