Google Research uses smartwatch sensors and AI to detect signs of high blood pressure
What happened
On November 7, The Decoder reported on a Nature study from Google Research. It used the pulse and motion sensors in ordinary smartwatches, with AI, to detect signs of high blood pressure without calibration from a blood pressure cuff. A neural network learned pulse and heartbeat patterns from nearly 500,000 hours of sensor data. In a 196-person study across five US sites, the method identified high blood pressure 65.8% of the time, against 55.3% for standard office measurement.
