Abstract Materials with target load plateaus offer the potential for developing innovative vibration suppression and isolation systems applications such as satellite platforms, submarines, electric vehicles. However, implementing these materials can pose significant challenges. In this study, stair‐stepping mechanical metamaterials programmable are presented, which created via a three‐level (unit, module, 3D object) construction strategy. The strategy inspired by inverse design concept achieves tunability in number properties of within force–displacement profiles metamaterials. This approach even yields appealing response patterns, validated experiments finite element simulations. Promisingly, programming unit from its initial configuration to “zero stiffness” enables excellent performance. Furthermore, two reversible methods proposed switching among various configurations, namely shape memory supporting payload. opens up new possibilities creating customized responses. It also provides opportunities incorporate multimodal capabilities into precision devices.

Abstract Existing mechanical metamaterials are typically designed to either withstand loads as a stiff structure, shape morph floppy mechanism, or trap energy multistable matter, distinct behaviours that correspond three primary classes of macroscopic solids. Their stiffness and stability sealed permanently into their architecture, mostly remaining immutable post-fabrication due the invariance zero modes. Here, we introduce an all-in-one reprogrammable class Kagome enable in-situ reprogramming modes access apparently conflicting properties all classes. Through selective activation metahinges via self-contact, architecture can be switched acquire on-demand rigidity, floppiness, global multistability, bridging seemingly uncrossable gap between structures, mechanisms, matters. We showcase versatile generalizations metahinge remarkable reprogrammability for range including stiffness, signal guiding, buckling modes, phonon spectra, auxeticity, opening plethora opportunities materials devices.
