Abstract Intelligent impact‐protection wearable devices often require intricate circuitry to operate, which hinders the timely display of impact‐related injuries. Consequently, it is imperative develop intelligent protective materials that are self‐sufficient and capable visualization. In this work, impact protection material shear‐stiffening gel (SSG) combined with mechanoluminescent (ML) ZnS:Cu/PDMS@SiO 2 create ML‐SSG. This embodies various features, including protection, force visualization, flame resistance, long‐distance passive control, making ideal for devices. light significant shear stiffening effect SSG, ML‐SSG effectively dissipates up 80% energy exhibits excellent resistance. Concurrently, also visualizing injuries, displaying warning in real‐time via mechanoluminescence, assessing based on intensity mechanoluminescence. The incorporation SiO ZnS:Cu has resulted remarkable flame‐retardant property. innovative significantly improves performance complex environments. addition, realizes human–computer interaction through neural network mechanoluminescence characteristics. research expands potential applications multifunctional complicated environments, thereby promoting development
