Problem solved: Sepsis and cardiovascular events are leading causes of death worldwide, with delayed diagnosis a primary factor. Current monitoring relies on bulky, intermittent equipment or invasive methods, leaving critical gaps in continuous care especially for at-risk populations in remote or resource-constrained environments.

Benefits: Enables detection hours ahead, potentially reducing mortality and complications by 40-60%, dramatically lowers healthcare costs, empowers non-specialists and remote monitoring, eliminates battery waste, and works reliably off-grid.

How it works: An ultra-thin flexible adhesive patch (5 cm diameter) applied to the neck, wrist, or temple uses a stretchable ultrasound array for continuous Doppler blood flow and velocity measurement, combined with optical sensors for perfusion and oximetry, plus bioimpedance. Data is fused in an onboard edge-AI processor running lightweight models to estimate blood viscosity and generate risk scores. It triggers immediate local alerts and sends data via wireless connection to a companion app or care system for predictive insights (e.g., “High sepsis likelihood – recommend intervention”).

Novelty/improvement: The first single-patch solution integrating continuous Doppler flow monitoring, AI-driven viscosity estimation, and complete self-powered operation. It advances existing wearable technologies by removing battery dependency and delivering true always-on predictive capability in a compact, affordable form.

Applications: Intensive care units and emergency rooms, home and elderly monitoring, field medicine, ambulances, telehealth platforms, chronic disease management, and global health initiatives.

Market potential: Positioned within the rapidly growing multi-billion-dollar wearable diagnostics and critical-care monitoring market, with strong scalability for both developed and emerging healthcare systems worldwide. Offers clear licensing or commercialization pathways.

How manufactured: Produced using established roll-to-roll printing and flexible hybrid electronics techniques on biocompatible substrates, similar to advanced wearable and sensor fabrication processes. Assembly leverages widely available materials and standard industry lines for rapid scaling.

Production cost vs. market: Projected at $5–10 per unit at volume, delivering exceptional value compared to weekly costs of current continuous glucose monitors or hospital-grade monitors that can exceed hundreds of dollars per use case.

This invention promotes health equity, reduces system burdens, and advances sustainable, accessible medical technology for a better future.
