Smart structure has the characteristics of active deformation, variable stiffness, large-size

molding, etc., and has shown great application potential and practical value in aerospace,biomedicine and other fields. The smart deformable structure combines smart materials with 4Dprinting technology to achieve multi-modal active response capability under external excitation.This report will focus on typical smart materials and introduce their new ideas and newachievements. Based on mechanical theory and material research, a variety of shape memorypolymers were invented; a variety of active deformation structures were invented and successfullyapplied in the Tianwen 1 Mars probe. A variety of deformable intelligent structures such asintelligent actuators, and zero Poisson ratio/negative Poisson ratio cellular structures have beendeveloped.
