Develops and tests an ultra-flexible hydrogel for chronic neural interfaces, suggesting improved signal quality and reduced immune response.
. We further developed an in-plane swelling control with a dry, soft-protective etching strategy that preserves the structural integrity during hydrogel processing. The resulting all-organic ECoG array conforms to the cortical surface, minimizing foreign body response and providing exceptional signal quality, with the longest record up to 550 d.
