FaceBit, a very useful sensor to attach to your N95 mask – All Senegalese news in real time | All the news in Senegal today: sport, Senegalese politics, people and miscellaneous facts in Senegal

FaceBit is a small sensor to be placed in an N95 mask, a sensor that records a certain number of health data.

Wearing a mask has become routine due to the Covid-19 pandemic still raging across the planet, but these masks could soon be used for more than “just” protecting ourselves and others. Researchers at Northwestern University (including the creator of the Game Boy battery-free Josiah Hester) have developed FaceBit, a mask sensor that can analyze a number of health constants directly from inside a simple N95 mask. Fixed magnetically, it makes it possible in particular to determine the heart rate of the wearer of the mask and even to detect possible leaks or a bad position of the mask.

These measurements can later help the sensor detect a number of health issues. Heart and breathing data can help identify when you’re stressed and need a break. And while the sensor isn’t a substitute for an N95 mask fit test, it can help you maintain that fit throughout the day.

And there might not be a need to recharge that sensor either. Indeed, although there is indeed a battery in the prototype, the sensor uses the force of the breath, the heat, the movement and the Sun to extend the longevity of the system to 11 days. Josiah Hester would even like the mask to be completely battery-free.

The FaceBit will still have to pass a battery of clinical tests and other tests of all kinds before it can possibly be ready for the general public. That being said, Josiah Hester’s team has already released the code for the project and the various components to help those interested in building it and verifying that it works. While you probably won’t buy one for yourself, this little innovation could be of great interest to hospitals looking to keep their staff safe throughout their working days.
