Google's AI detects high blood pressure from a regular smartwatch without a cuff

Google researchers have developed an AI model that estimates blood pressure by analyzing pulse and motion data from standard smartwatch sensors. In a study of 196 participants, the tool demonstrated a 65.8 percent detection rate for hypertension, outperforming conventional in-office blood pressure measurements. This technology is now integrated into the Google Health app, offering a potential shift toward continuous, non-invasive health monitoring that does not require a traditional inflatable cuff.
