## Description

- description: Variable-stiffness materials have a unique ability to change their
    stiffness reversibly in response to external stimuli or conditions. However, achieving
    ultrahigh stiffness change is often constrained by the geometric organization
    of the microstructures in most materials that exhibit variable stiffness. Therefore,
    to overcome this limitation, we introduce a metamaterial design inspired by triply
    periodic minimal surfaces for fabricating multiphase metamaterials. The specific
    geometric features of minimal surface designs facilitate interlocking bi- or tri-continuous
    interpenetrating phases such as air, resin, and alloy within a single multiphase
    metamaterial. These multiphase metamaterials are constructed by injecting a low-melting-point
    alloy (LMPA) into a 3D-printed elastic resin mold. The thermally-induced solid-liquid
    phase transition of the LMPA governs the stiffness change in multiphase metamaterials,
    ranging from Kilopascals to Gigapascals. Further contributing to this phenomenon,
    the superior resilience of the elastic resin enhances the shape-memory effect
    of the multiphase metamaterials. Applications of these materials in origami and
    deployable structures have been successfully demonstrated, highlighting their
    reconfigurability and volume compressibility. This innovative design strategy
    provides the foundation for crafting other metamaterials with intricately arranged
    internal phases. In conclusion, the proposed multiphase metamaterials have promising
    potential for various engineering applications where adaptability and morphing
    capabilities are essential.
