Abstract Auxetic metamaterials refer to materials and structures with extraordinary deformation, i.e., transverse expansion (contraction) under uniaxial tension (compression). In recent decades, a very wide range of innovative functional performance has been discovered stemming from this behavior. This desirable exhibition adaptivity, programmability, functionality provides great potential in soft intelligent systems. However, thus far, the mainstream research on auxetic focused subjective design, monotonic mechanical properties, passive tunability. review thorough overview classical properties applications, primary objective proposing new roadmap auxetics for advances interdisciplinary field. The fundamental works are categorized different configurations mechanisms. particular, integration shape morphing, actuation, sensing, multiphysical response, inverse design is reviewed detail. To accelerate development smart structural systems, applications generalized into robotics (outside body), human–machine interaction (surrounding healthcare devices (inside body). Finally, several significant topics emphasized theory, material choice, manufacturing technique, applications.

ABSTRACT Aiming at the problem of rough and porous surfaces mechanical properties thermoplastic polyurethane elastomer (TPU) parts prepared by selective laser sintering, this article used dip‐dyeing process to improve surface modification TPU parts. It researched solvent type, temperature, time, pH value dyeing solution, initial concentration dyes on performance, properties, analyzed mechanism immersed in simultaneous dyeing. After dip‐dyeing, formed a homogeneous integument; roughness was reduced from 23.3 μm original 0.3 dyed The apparent performance dirt resistance are improved, colorfastness rate is 4 or more. Simultaneous efficiently improved through impregnation. When DMF solution used, temperature 30°C time 60 s, tensile strength reached 4.51 MPa elongation break 421.1%, which 61.48% 108.2% higher than that
