Google research detects hypertension cuff-free with smartwatches
What happened
On 6 November 2026, Google Research published a study in Nature proposing AI-PPG-ACC-HTN, a multimodal AI system that passively identifies hypertension status using photoplethysmography (PPG) and accelerometer (ACC) signals from smartwatches, without cuff calibration. Reports say the system identifies signs of hypertension from watch sensor data, and progress so far is limited to the research publication.
