Fitbit study looks into non-cuff blood pressure monitoring

Smartwatches have become portable mini diagnostic centers, in no small part thanks to Apple’s push for sensors that keep track of various aspects of the wearer’s health. Those sensors have come a long way and are now able to track not just heart rate but also blood oxygen levels, sleep quality, and even ECG. There are, however, still a few biometrics that can’t be easily measured using just a fitness tracker or smartwatch, like glucose levels or blood pressure, and Fitbit’s research Labs is trying to find a way to make at least the latter easier.
