‘Soft’ Graphene-Containing Electrodes That Adapt to Living Tissue – Printed Electronics World

Posted: July 6, 2021 at 1:46 am

Researchers from The University of Manchester and Harvard University have collaborated on a pioneering project in bioengineering, producing metal-free, hydrogel electrodes that flex to fit the complex shapes inside the human body.

Replacing rigid metals

Tringides and Mooney, in collaboration with the Nanomedicine Lab in Manchester, identified a mixture of graphene flakes and carbon nanotubes as the best conductive filler, replacing the use of traditional rigid metals.

Cinzia Casiraghi, Professor of Nanoscience from the NGI and Department of Chemistry at Manchester, said: "This work demonstrates that high-quality graphene dispersions - made in water by a simple process based on a molecule that one can buy from any chemical supply - have strong potential in bioelectronics. We are very interested in exploiting our graphene (and other 2D materials) inks in this field."

Collaborative effort

Kostas Kostarelos, Professor of Nanomedicine and leader of the Nanomedicine Lab, added: "This truly collaborative effort between three institutions is a step forward in the development of softer, more adaptable and electroactive devices, where traditional technologies based on bulk and rigid materials cannot be applied to soft tissues such as the brain."
