The mask sensor can detect your leak and heart rate

You may not be happy about it mask are part of everyday life during the COVID-19 pandemic, but they may soon be more helpful than protecting others and yourself. Researchers at Northwestern University (including Game Boy does not consume battery creator Josiah Hester) has developed mask sensor “FaceBit” can monitor a variety of health data from inside the N95 mask. The magnetically attached unit can measure your heart rate using subtle head movements from the blood pumping and can detect leaks or mismatches by looking for sudden drops. suddenly in the resistance of the mask.

In turn, those measurements can help the sensor detect a range of other conditions. Heart and breathing data can tell you when you’re stressed and need a break. And while the sensor won’t replace the N95’s fit test (to verify proper sealing), it’s powerful enough to help you maintain that fit all day long.

You also may not have to charge the sensor. While the prototype has a battery, the sensor uses breathing force, heat, motion, and the Sun to extend the mask’s life to 11 days. Ultimately, Hester wanted the mask to be battery-free.

FaceBit will need to go through clinical trials and other tests before it’s ready for real-world use. However, Hester’s group was project release public code and hardware to help others build and verify it. While you probably won’t buy one of these for personal use, it could be crucial for hospitals looking to keep workers safe and prevent burnout. during long shifts.
