弗吉尼亚理工学院和 Meta AI 的研究团队提出了一种名为 UNIMATE 的统一模型，通过创新的模型架构解决了当前超材料 AI 设计中的关键瓶 颈，首次实现了对超材料设计三大核心要素，即三维拓扑结构、密度条件和力学性能的统一建模与协同处理。 超材料是一类由人工设计的亚波长结构组成的材料，能够突破天然材料的固有限制，实现对电磁波的精确调控，如负折射率、超透镜、隐身技术等。其 中，机械超材料作为一类拥有特殊力学性能的人造材料，在航空航天、生物医药、能源存储等多个领域展现出巨大的应用潜力。其独特之处在于性能并非 由材料的化学成分决定，而是通过精心设计的微观结构来实现。例如，具有负泊松比的超材料在拉伸时会横向膨胀，这种特性使其在柔性器件中具有重要 应用价值；而具有高能量吸收行为的超材料则适用于缓冲装置。 在材料科学与人工智能交叉领域，超材料的设计与优化一直是备受关注的研究方向。在机械超材料的设计过程中，通常涉及三个关键模态：3D 拓扑结 构、密度条件和力学性能。这三个模态之间存在着密切的关联，已知其中任意两个模态，就可以推导出第三个模态。然而，研究团队通过全面回顾现有文 献发现，大多数已有研究仅考虑其中两个模态。 ...
