Using only resources built into a phone, University of Washington researchers have developed an app that uses inaudible sonar to monitor someone’s breathing rate, and can deduce when drug overdose has stopped breathing. Called Second Chance, it is claimed to detects opioid overdose-related symptoms ~90% of the time, and can track someone’s breathing from up ...
