Unlike traditional e\u2010skin, ionic skin utilizes a polymer network scaffold with mobile ions, effectively overcoming the issue of poor dispersion of conductive fillers in polymer matrices. As an ionic liquid with facile synthesis and low cost, 1\u2010ethyl\u20103\u2010methylimidazolium chloride ([EMIM]Cl) forms strong interactions with both polymers and water molecules. Cellulose is a natural polymeric material with advantages such as low cost, environmental friendliness, and renewability. 2,2,6,6\u2010Tetramethylpiperidinyl\u20101\u2010oxyl (TEMPO)\u2010oxidized cellulose nanofibrils (TOCNs) exhibit excellent biocompatibility. In this work, the TOCN\u2010[EMIM]Cl ionic hydrogel was formed by mixing a TOCN dispersion with [EMIM]Cl ionic liquid, followed by Ca\n                    <jats:sup>2<\/jats:sup>\n                    <jats:sup>+<\/jats:sup>\n                    cross\u2010linking.
