Idea
Smartphone-based cuffless blood pressure estimation platform delivering clinical-grade accuracy using photoplethysmography attractor features.
Research Paper
Core Innovation
This paper presents Attractor-Vascular Coupling Theory (AVCT), a novel mathematical framework linking cardiac attractor geometry from PPG signals to blood pressure. It demonstrates that smartphone PPG attractor features alone can achieve AAMI-standard BP estimation accuracy, validated with rigorous cross-validation and outperforming prior multi-sensor approaches.
Why It Matters
Accurate blood pressure monitoring is critical for managing cardiovascular health but current methods require bulky cuffs or multiple sensors. This solution enables convenient, continuous, and non-invasive blood pressure tracking using only a smartphone camera, reducing costs and improving accessibility. It can transform hypertension management and remote patient monitoring at scale.
Market Size (TAM)
$20–50B TAM for digital health monitoring; $2–10B SAM from healthcare providers and telemedicine platforms. 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 that enables accurate cuffless 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 requiring ECG, enabling blood pressure monitoring solely via smartphone cameras.
