Inspired by the starfish's unique ability to achieve flexibility and posture-holding with minimal energy expenditure, we present a novel bioinspired morphing structure. Our two-component design, consisting of a thermoplastic mesh and elastomeric jacket, effectively mimics the functions of the starfish's ossicles, mutable collagenous tissues, and derma. This structure exhibits a remarkable combination of self-healing, time-dependent shape memory, and self-posture-holding properties. Systematic variations in mesh geometry demonstrate precise control over structural stiffness and thermal response, enabling customization for specific applications. The structure's scalability and ease of fabrication further enhance its adaptability. We experimentally demonstrate the potential of our biomimetic morphing structure using several prototypes. This work lays the foundation for developing a new type of versatile morphing structures with applications in diverse fields, including robotics, biomedical devices, and adaptive structures.
受海星以最小能量消耗实现灵活性和姿势保持的独特能力启发，我们提出了一种新型的仿生变形结构。我们的双组分设计由热塑性网和弹性体护套组成，有效地模仿了海星的小骨、可变胶原组织和皮肤的功能。这种结构展现出自我修复、时间依赖性形状记忆和自我姿势保持特性的显著组合。网几何形状的系统变化展示了对结构刚度和热响应的精确控制，从而能够针对特定应用进行定制。该结构的可扩展性和易于制造进一步增强了其适应性。我们使用几个原型通过实验证明了我们的仿生变形结构的潜力。这项工作为开发一种新型的多功能变形结构奠定了基础，该结构可应用于包括机器人技术、生物医学设备和自适应结构在内的各种领域。
