Self-Powered Smart Vascular Grafts for Real-Time Implant Monitoring

healthPrototypeTRL 3

Imagine a heart bypass graft that acts like a tiny power plant, turning the movement of your blood into electricity. This removes the need for bulky batteries that eventually run out and require more surgery to replace. It allows the graft to send health alerts directly to a smartphone, letting doctors catch problems before they become emergencies.

The business problem

What needed solving

Traditional vascular grafts have failure rates up to 50% because they cannot be monitored in real-time. Current implantable electronics are limited by battery life, making continuous monitoring impossible.

The solution

What was built

A triboelectric nanogenerator (TENG) for energy harvesting, a miniaturized power management unit, and a wireless transmission system integrated into a vascular graft (iGraft).

Who can put this to work

Medical Devices
enterprise
Target: Cardiovascular implant manufacturer

If you are a medical device company dealing with graft failure rates up to 50% due to thrombosis or infection — this project developed the iGraft that uses energy harvesting to monitor performance and send alerts to avoid failure.

Digital Health
mid-size
Target: IoMT (Internet of Medical Things) platform provider

If you are a digital health provider dealing with the limitation of battery life in implantable systems — this project developed a wireless system and power management unit that transmits data to smartphones or watches.

Biomaterials
SME
Target: Specialized biocompatible materials developer

If you are a materials company dealing with the lack of active sensing in vascular grafts — this project developed triboelectric nanogenerators (TENG) that convert mechanical body energy into electrical power.

Frequently asked

Quick answers

What is the estimated cost or price of the iGraft system?

Based on available project data, specific pricing or cost structures for the final product have not been disclosed.

Is the technology ready for industrial scale production?

The project is currently in the validation phase using in vitro and in vivo testing; industrial scaling details are not provided in the current reports.

What is the IP and licensing status of the TENG technology?

Based on available project data, there is no specific mention of patents or licensing agreements, though the project is led by research institutions.

How does the system integrate with existing healthcare infrastructure?

The system is designed to wirelessly transmit data to external electronic devices such as smartphones or watches, which then alert the healthcare system.

What is the timeline for market availability?

The project period runs from 2023-10-01 to 2026-11-30, suggesting the technology is still in the development and validation stage.

Consortium

Who built it

The consortium is purely academic and research-driven, consisting of 4 partners from 3 countries (AT, ES, PT). With 3 universities and 1 research institution, there is a 0% industry ratio, indicating the project is currently focused on high-risk, high-reward scientific discovery rather than immediate commercialization.
