Google Research presents a smartwatch AI system for detecting hypertension without cuff calibration
AIGoogle Research says a multimodal AI system using smartwatch PPG and accelerometer data can passively detect signs of hypertension without cuff calibration. In a 196-participant, five-site study benchmarked against 24-hour ambulatory blood pressure monitoring, the system reached 65.8% sensitivity and 90.0% specificity for initial screening.
