) and maintains stable impedance under continuous hydration. Integrated as a wearable electrode interface, CMCDA' supports reliable electrocardiogram acquisition for one week, outperforming the commercial conductive gel at curved body sites. These results highlight oxidative-cross-linked, cellulose-derived hydrogels as sustainable ionically conductive interfaces for long-term wearable bioelectronics.
