Abstract The capacity of biological tissues to undergo self‐healing is crucial for the performance functions and continuation life. Conventional intrinsic materials demonstrate analogous functionality depending on dissociation‐recombination reversible bonds with no need extra repair agents. However, trade‐off relationship between mechanical strength kinetics in systems, coupled lack additional functionality, restricts their service life practical applications. Diversified highly ordered structures organisms significantly affect energy dissipation mechanism, signal transmission efficiency, molecular network reconstruction capability due multi‐dimensional differentiated macroscopic composite constructions, microscopic orientation textures, topologies/bonding types at level. These architectures exhibit distinctive strengthening mechanisms functionalities, which provide valuable references. This review aims providing current status advanced biomimetic internal micro/nanostructures. Through highlighting specific examples, classifications, design inspirations, fabrication strategies these newly developed based integrating dynamic interactions nano/microstructures are outlined. Furthermore, balance mechanisms, structure–functionalization relationships, potential application values discussed. concludes a perspective challenges, opportunities, prospects development, application, promotion self‐healable bio‐like architectures.

Currently, the development of hydrogels with excellent mechanical properties (elasticity, fatigue resistance, etc.) and conductive can better meet their needs in field flexible sensor device applications. Generally, a denser cross-linking density tend to have properties, but improvement comes at expense reduced electrical conductivity. Directly generating CaCO3 hydrogel prepolymer not only increase its network also introduce additional ions enhance internal ionic strength, which is beneficial improving conductivity hydrogel. It still big challenge directly generate static solution ensure uniform dispersion Herein, we adopted an improved preparation method that generated particles be evenly dispersed until polymerization completed. Finally, PAM/PVA/CaCO3 supertensile, compressive, toughness, resistance was prepared. In addition, presence free Na+ Cl– gives sensing performance monitor daily human activities. On basis application information communication, further deepened this by combining characteristics themselves. Combined ASCII code, applied exchange encryption decryption, achieving antitheft function smart locks. A variety integrated broad prospects for sensors, highlighting great potential human–computer interaction intelligent protection.
