Creating durable, motion-compliant neural interfaces is essential for accessing dynamic tissues in vivo and linking neural activity with behaviors. Here, the authors introduce carbon nanotube-enhanced polyvinyl alcohol hydrogels, creating electrically anisotropic, fatigue-resistant fibers for long-term intraspinal electrophysiological recordings in mice.
