Google Research Introduces SensorFM: A Wearable Health Foundation Model Pretrained on One Trillion Minutes of Sensor Data
One trillion minutes of sensor data. Google just released SensorFM—a foundation model that redefines what's possible in wearable health AI.
Why it matters
Google Research demonstrates a new frontier in foundation models: scaling laws apply beyond text and images to unlabeled sensor signals. SensorFM's pretraining on 1T minutes from 5M participants and its performance across 34/35downstream health tasks signals a shift toward multimodal, real-world health AI that could reshape clinical workflows and consumer wearables.
The key facts
