Mechanical metamaterials have considerable application potential, but are often limited to single applications owing to material and manufacturing constraints. To achieve a “single structure, multiple applications” goal, this study presents a multifunctional metamaterial structure. The metamaterial cells gain significant deformation and recovery abilities by incorporating the concept of a tensegrity structure to balance flexibility and rigidity and using a rigid-flexible fabrication process. Inspired by cat-tongue barbs and Hooke's law, an innovative pre-stress programming structure is designed for integrated fabrication, enabling multilevel pre-stress control for each cell. This programmable stress allows the twin-cell array to transition in situ from monostable to bistable states and provides multilevel critical-force functions for bistable states. After assembling a nine-cell array, the structure offers a wide range of adjustable stiffness levels, enabling soft-rigid transitions and varied force-displacement responses without the need for additional tools. It also allows controlled collapse ratios and deformation through stiffness control. Additionally, the nine-cell array features isotropy with a Poisson ratio of v = −1 and clear indentation resistance. This approach is promising for applications such as adjustable energy dissipators, automotive equipment, and passive safety.
