Abstract

MXene (Ti 3 C 2 T x )‐based hydrogels hold great promise for wearable bioelectronics but are limited by unstable interlayer spacing, poor mechanical resilience, and inadequate skin compatibility. An ion‐driven interfacial engineering strategy is introduced that stabilizes Ti 3 C 2 T x nanosheets via Ca 2+ intercalation and Cl − electrostatic screening, expanding interlayer spacing and enabling ultrafast gelation (
