Thick-panel origami structures forming seamless surfaces3D打印与折纸艺术完美结合：无缝可展开结构 |
Thick-panel origami structures are able to deploy into expansive configurations, making them suitable for industrial applications such as deployable stadium domes, water-tight roof tiling, sun shields, furniture, antennas, solar arrays, space telescopes, etc. Existing methods often introduce structural complexities or fail to ensure seamless surfaces, limiting their practicality. Here our process involves modifying valley-crease panels and extending adjacent panels to eliminate grooves, thus achieving a seamless surface. The paper presents the geometric conditions for ensuring motion compatibility and analyzes the kinematics of the modified structures. Additionally, an approach for minimizing the number of top panels is proposed to simplify fabrication and enhance lightweight design. Prototypes of these designs are 3D-printed to validate the concepts. The methods and results offer valuable insights for developing deployable structures with customizable shapes and enhanced functionality.

随着航空航天技术的快速发展，未来航天器对结构、性能和功能的要求愈加严苛，轻量化、高强度、具备多功能和多模态变形能力的材料设计成为关键需求。折纸超材料因其独特的几何设计和力学特性，具有可重构、多稳态和能量吸收的特性，已成为航空航天领域的研究热点。这类材料通过精密折叠结构，结合现代数学建模与材料科学，具备可调控变形、轻量化、易展开与回缩等优势。在航天领域，折纸超材料不仅应用于可展开结构（如天线、太阳能帆板等），还在减震、吸能、防护等方面展现出潜力。折纸超材料的可编程几何特性赋予航天器自适应变形能力，能应对太空环境中的外部压力和温度变化，提升结构可靠性与寿命，并有效降低发射成本。本文综述了折纸超材料的特性、设计方法、制造技术及应用，探讨其在航空航天中的发展趋势与未来研究方向。

模块化手性折纸超材料，开启可编程多模态新时代 |
具有多模态变形机制的超材料类似机器，尤其是在具备自主功能时。一种典型的可调控手性的结构组件能将线性运动转化为旋转运动。这些具有类似机器双模态的手性超材料在波操控、与圆偏振相关的光学活性以及手性活性流体等领域具有潜在应用。然而，双运动本质上是耦合的，无法独立控制，且它们仅限于小变形（即应变≤2%），这限制了其应用。在这里，我们构建了模块化手性超材料，由拉胀平面镶嵌和受折纸启发的柱状阵列组成，实现了解耦驱动。在单自由度驱动下，组件的扭转角度在 0° 到 90° 之间，面内收缩可达 25%，面外收缩超过 50%。通过实验和模拟，我们发现组件的变形包括由旋转方形镶嵌主导的面内扭转和收缩，以及由管状 Kresling 折纸阵列主导的面外收缩。此外，我们展示了两种不同的驱动条件：自由平移的扭转和自由旋转的线性位移。我们的超材料基于高度模块化的组件构建，实现了可编程的不稳定性、局部手性控制、可调的承载能力和可扩展性。我们的概念为实现多模态、多稳态和可编程机器提供了途径，可应用于机器人变形器、温度调节、滞后回线中的机械记忆、非对易状态转换以及用于能量吸收和信息加密的即插即用功能组件。

Exotic mechanical properties enabled by countersnapping instabilities
|
Mechanical snapping instabilities are leveraged by natural systems, metamaterials, and devices for rapid sensing, actuation, and shape changes, as well as to absorb impact. In all current forms of snapping, shapes deform in the same direction as the exerted forces, even though there is no physical law that dictates this. Here, we realize countersnapping mechanical structures that respond in the opposite way. In contrast to regular snapping, countersnapping manifests itself in a sudden shortening transition under increasing tension or a sudden increase in tensile force under increasing extension. We design these structures by combining basic flexible building blocks that leverage geometric nonlinearities. We demonstrate experimentally that countersnapping can be employed to obtain new exotic properties, such as unidirectional stick–slip motion, switchable stiffness that does not otherwise affect the state of the system, and passive resonance avoidance. Moreover, we demonstrate that combining multiple countersnapping elements allows sequential stiffness switching for elements coupled in parallel, or instantaneous collective switching for elements in series. By expanding the repertoire of realizable elastic instabilities, our work opens routes to principles for mechanical sensing, computation, and actuation.

MIT engineers print synthetic “metamaterials” that are both strong and stretchy
MIT engineers have now found a way to fabricate a metamaterial that is both strong and stretchy. The base material is typically highly rigid and brittle, but it is printed in precise, intricate patterns that form a structure that is both strong and flexible.
The key to the new material’s dual properties is a combination of stiff microscopic struts and a softer woven architecture. This microscopic “double network,” which is printed using a plexiglass-like polymer, produced a material that could stretch over four times its size without fully breaking. In comparison, the polymer in other forms has little to no stretch and shatters easily once cracked. |
科学家造出“刚柔并济”的神奇材料，硬如钢铁，柔似橡胶，拉伸4倍不破裂
这种新材料的双重特性关键在于其结合了坚硬的微观支撑结构和柔软的编织架构。这种微观的“双重网络”是通过一种类似有机玻璃的聚合物打印而成，能够制造出一种材料，使其在不完全断裂的情况下可以拉伸至其原始尺寸的四倍以上。相比之下，其他形式的聚合物几乎没有伸展性，一旦出现裂痕就会很容易碎裂。
