ERC Proof of Concept Grant

Implantable electrode arrays are a key component of neuroprosthetic systems. They are used clinically to restore functions of the nervous system lost through injuries or degenerative diseases. Examples include cochlear implants and deep brain and spinal cord stimulators. However, existing systems have weaknesses. The implants currently used usually consist of metals such as platinum encapsulated in silicone. These materials are characterized by mechanical properties that are very different from the host tissues. This often causes suboptimal tissue integration in the long term and can lead to inflammation and scar formation.

Connecting biological tissue with electrical systems

One promising approach lies in bioelectronic materials that connect biological tissue with electrical systems. “Our special coating is based on a bio-inspired hydrogel, a soft material that consists largely of water. By incorporating conductive polymers, we achieve excellent electrical properties. Thus, our coating has properties similar to those of tissues. We hope that this will have a profound effect on establishing a good biological and electrical interface,” explains Ivan Minev, Professor of Electronic Tissue Technologies at EKFZ for Digital Health at TUD and Leibniz-IPF. He has already previously received prestigious ERC funding for his research – a Starting Grant and a Consolidator Grant.

From laboratory to clinical application

The project includes extensive tests to characterize the new coating and its subsequent investigation in preclinical studies. Priv.-Doz. Dr. med. habil. Witold Polanski, an experienced neurosurgeon at Dresden University Hospital, will contribute valuable clinical expertise: “This funding enables us to bridge the gap between basic research and clinical application. COATARRAY has the potential to significantly increase the performance and durability of implanted electrode arrays – which would be of great benefit to patients in particular.”

Market potential will be analyzed and regulatory requirements are examined at an early stage of the project. Experts from the Regulatory Affairs Office of the EKFZ for Digital Health provide support in this process. The joint goal is to bring new medical devices into clinical use as fast as possible. In addition to regulatory requirements, potential patents and subsequent commercialization are also considered early on. The TUD|Excellence Center for Innovation, Transfer and Entrepreneurship (TUD|excite) provides support in this area. The Swiss start-up Neurosoft Bioelectronics will supply some of the electrode array designs on which the coating will be tested.

“I am grateful for the opportunity to further advance our translational efforts in bioelectronics through ERC funding. Our approach could not only improve existing neuro-prosthetic systems, but also enable completely new treatment methods. I hope that our project will help to sustainably improve the quality of life of patients in the future,” says Professor Minev.

The project is being carried out in collaboration between EKFZ for Digital Health, the Department of Neurosurgery at Dresden University Hospital and with the support of the TUD|Excellence Center for Innovation, Transfer and Entrepreneurship (TUD|excite). It is funded over a period of 18 months with 150,000 Euros.

About the ERC Proof of Concept Grants

The Proof of Concept (PoC) Grant is a funding line of the European Research Council (ERC) that can be awarded in addition to the main funding lines (Starting, Consolidator, Advanced and Synergy Grant). It is aimed exclusively at researchers who already hold an ERC grant and now wish to explore the commercial or societal potential of their pioneering research projects. PoC grants are endowed with 150,000 Euros for a maximum of 18 months. The grant scheme is part of the EU’s research and innovation program, Horizon Europe. In the final round of the 2024 ERC PoC grant competition, 134 projects will receive support, bringing the total number of grants awarded under the 2024 work program to 245 worth 36.75 million Euros.
