Muscle‐Inspired Highly Anisotropic, Strong, Ion‐Conductive Hydrogels

Biological tissues generally exhibit excellent anisotropic mechanical properties owing to their well‐developed microstructures. Inspired by the aligned structure in muscles, a highly anisotropic, strong, and conductive wood hydrogel is developed by fully utilizing the high–tensile strength of natural wood, and the flexibility and high‐water content of hydrogels. The wood hydrogel exhibits a high–tensile strength of 36 MPa along the longitudinal...
