Researchers have developed BCG-FM, a novel foundation model for analyzing cardiac health through ambient mechanical biosignals. This model utilizes a piezoelectric sensor embedded in a bed surface to record ballistocardiography (BCG) data overnight, requiring no user effort. Pretrained on 2.75 million hours of recordings from nearly 146,000 individuals, BCG-FM achieved a 3.26-year Mean Absolute Error in biological age estimation and demonstrated clinically relevant discrimination across various health conditions.
