摘要：
机械超材料——具有由其内部架构产生的非寻常特性的结构——被设计为经历大变形时，通常利用大的内部旋转，因此需要引入柔性铰链。在机构极限下，这些超材料由通过理想铰链连接的刚体组成，这些铰链以零能量代价变形。然而，在这一极限下制造结构一直难以实现。在这里，我们展示了纺织铰链的制造和集成提供了一个可扩展的平台，用于创建具有类机构行为的大型结构化超材料。此外，利用最近引入的运动学优化工具，我们证明了纺织铰链能够实现极端的形状变形响应，为开发下一代基于机构的超材料铺平了道路。
英文摘要：
Mechanical metamaterials -- structures with unusual properties that emerge from their internal architecture -- that are designed to undergo large deformations typically exploit large internal rotations, and therefore, necessitate the incorporation of flexible hinges. In the mechanism limit, these metamaterials consist of rigid bodies connected by ideal hinges that deform at zero energy cost. However, fabrication of structures in this limit has remained elusive. Here, we demonstrate that the fabrication and integration of textile hinges provides a scalable platform for creating large structured metamaterials with mechanism-like behaviors. Further, leveraging recently introduced kinematic optimization tools, we demonstrate that textile hinges enable extreme shape-morphing responses, paving the way for the development of the next generation of mechanism-based metamaterials.
