Researchers have developed a novel deep learning framework called Phy-BP for contactless blood pressure monitoring using triaxial bodyseismography (BSG). This system extends traditional ballistocardiography (BCG) by incorporating an adaptive quality-control algorithm to select relevant BSG segments and embedding a physical model of 3D wave propagation into the deep learning architecture. This physics-constrained approach aligns multi-axis features during training, enhancing robustness against real-world distortions and improving performance even with limited training data. Experiments on a substantial hospital dataset demonstrated Phy-BP's ability to filter low-quality measurements and provide accurate blood pressure monitoring. AI
