A new soft and elastic technology for neural implants have been developed in a collaboration between Linköping University, ETH Zurich, New York University and Columbia University, led by Assistant Professor Klas Tybrandt. The softness enables chronic integration of electronics with sensitive tissue, making it attractive for a wide range of biomedical applications. The technology is based on a novel gold nanowire composite which is biocompatible, long-term stable, and retains high conductivity up to 100 % strain. High density electrodes grids are fabricated by a tailor-made process. The soft neural grids provide outstanding recording quality during three months of implantation and can resolve high spatiotemporal neural signals.
