Abstract The exploitation of wearable electronic devices with diversified environmentally adaptivity, advanced additive manufacturing, efficient microwaves absorption, and self‐powered sensing represents a pivotal strategic in promoting Artificial‐Intelligence personal electromagnetic safety. However, achieving robust multifunctional integration single flexible device is still an unprecedented challenge. Herein, the multidimensional multiphase nanofiller hierarchical structures tailored defects, comb/bottlebrush polysiloxane multifluorination multireversible bond, featuring dynamic interface interaction, are designeded. Subsequently, dual‐mode intelligent sensor assembled based on direct‐ink‐writing electrostatic‐spraying technology. 3D‐printed triboelectric nanogenerator (TENG) exhibited excellent output ( V oc = 185.4 V, I sc 1576.2nA, power density 729.8mW m −2 ) durability virtue multi‐scale roughness surface, interfacial polarization, charge trapping, storage transmission capacity. Accordingly, fabric‐based TENG designed for demonstrating human activity monitoring biomechanical energy harvesting. Benefiting from optimized impedance matching multiple magnetic‐dielectric coupling, exceptional protection behavior RL min ‐64.81 dB, EAB 5.1 GHz). Remarkably, synergistic properties superhydrophobic, oleophobic, self‐healing significantly improved reliability life‐span. This work presents as proof‐of‐concept extensive design‐freedom, pioneering sensing, safety, which will contribute to development high‐quality human‐machine healthcare, skin.
