Abstract Robust and biocompatible hydrogels are recognized as promising biomimetic soft materials to improve human life quality. To ensure their stable, reliable, safe service, the further required have non‐contact wireless stress sensing ability. Herein, a mechanoluminescence (ML) based micellar hydrogel is developed, in which surface‐modified BaSi 2 O N : Eu 2+ (M‐BSON) particles chemically incorporated into cross‐linked polyacrylamide/polymethyl acrylate (PAM/PMA) network structure. Because of interactions between M‐BSON PMA micelles, as‐fabricated composite exhibits enhanced mechanical properties with strength 2.73 MPa toughness 3.40 MJ m −3 , respectively. The chemical wrapping by hydrophobic micelles protects ML from water quenching, leading remarkable stress‐induced luminescence under environment hydrogel. its desirable performance, attractive stress‐light responsiveness, good biocompatibility, has potential be applied an intelligent artificial ligament for self‐monitoring failure warning. This work addresses inhomogeneous dispersion quenching issues structure, significantly promote applications bionic engineering.
