Researchers have developed a new mathematical framework called Attractor-Vascular Coupling Theory (AVCT) to estimate blood pressure using smartphone photoplethysmography (PPG). This theory posits that cardiac attractor geometry contains sufficient information for accurate blood pressure readings. A model trained on AVCT-derived features achieved very low mean absolute errors for systolic and diastolic blood pressure, meeting stringent AAMI standards and demonstrating the potential for clinical-grade BP tracking with just a smartphone camera.
