Idea
Model delivering clinical-grade cuffless blood pressure monitoring using only smartphone camera photoplethysmography.
Research Paper
Core Innovation
This paper presents AVCT, a novel theory linking cardiac attractor geometry extracted from PPG signals to blood pressure, enabling accurate cuffless BP estimation. It validates the approach with a LightGBM model using smartphone PPG data, achieving AAMI-standard accuracy with fewer sensors and strict cross-validation, surpassing prior methods.
Why It Matters
Accurate blood pressure monitoring is critical for managing cardiovascular health but current methods require cumbersome cuffs or multiple sensors. This solution enables convenient, continuous, and reliable blood pressure tracking using just a smartphone camera, reducing barriers to widespread hypertension management and improving patient outcomes at scale.
Market Size (TAM)
$20–50B TAM for blood pressure monitoring devices; $2–10B SAM from healthcare providers and consumer health markets. Driven by rising hypertension prevalence and demand for remote patient monitoring.

Research Paper Overview
Attractor-Vascular Coupling Theory: Formal Grounding and Empirical Validation for AAMI-Standard Cuffless Blood Pressure Estimation from Smartphone Photoplethysmography
Summary
This work introduces Attractor-Vascular Coupling Theory (AVCT), a mathematical framework linking cardiac attractor geometry to blood pressure estimation using smartphone photoplethysmography (PPG). Validated on 46 subjects with strict cross-validation, the model achieves clinical-grade accuracy meeting AAMI standards without cuffs or multiple sensors, enabling reliable blood pressure tracking via smartphone cameras alone.
