Abstract
Extraneural Electrodes In article number 2203431, Youn Soo Kim and co-workers introduce an ideal conductive hydrogel for tissue-like extraneural electrodes with high conformability to improve the tissue–electronic interface. This hydrogel exhibits excellent adhesion, biocompatibility, non-swelling, and electrical conductivity in water. The hydrogel is implanted into the sciatic nerve of rats, and neuromodulation is successfully demonstrated through low-current electrical stimulation.
