Researchers from DTU are developing a non-invasive device that can monitor symptoms of a potential blood clot cheap and efficiently with novel IoT and sensor technology.

Around 15 million people in Europe alone are living with heart failure and are in the high-risk group for developing deep vein thrombosis (DVT). DVT occurs when a blood clot forms in one of the body’s deep veins, most often in legs. This can lead to death or severe disabilities.

Currently, physical examination and imaging are used in order to estimate or detect DVT or swelling in the body, but these processes are both slow and imprecise.

Researchers from DTU Fotonik, DTU Health Tech and DTU Electrical Engineering are now joining hands to develop a product that can monitor symptoms of DVT more efficiently and thus enable early treatment.

Collaborating and making an impact

The project combines a novel sensor and groundbreaking IoT technology in a so-called smart sock.

“The technology will be integrated in the sock or stocking where it will be able to sense changes in the body associated with DVT symptoms”, explains Assoc. Professor Sarah Renée Ruepp who is spearheading the project at DTU Fotonik.

In order to develop the smart sock, DTU Health tech is providing the sensors, DTU Electrical Engineering is developing electronics for interfacing of the sensors, and DTU Fotonik is providing loT technologies.

“We have a common goal to make it possible for both doctors and patients to monitor DVT cheap and efficiently. This technology will allow them to react early in case of a potential DVT occurrence”, says Assoc. Professor Sarah Renée Ruepp.

The smart sock is targeted those already at risk of developing blood clots, such as heart failure patients and post-knee/post-hip surgery patients.

“The collaboration between Departments means that we can make use of each others technological expertise to de-risk the technology in the short term and in the longer term to develop such a product”, she adds.

The project received DTU’s Discovery Grant in 2020 and will use said grant to make a working prototype. Down the road, they hope to found a new company based on the product.

DTU Discovery Grant

The DTU Discovery Grant is for early technical and commercial maturation and de-risking of technology. Each grant is up to 150,000 DKK, covering a period of up to 6 months.
