论文摘要
可重新配置的结构应用的未来主动超材料需要快速，不受限制，可逆和可重编程（多模式）转换性，并具有形状锁定性。本文中，我们旨在构建和演示一种磁性热力学工具，该工具使单个材料系统能够通过在形状内存组合物和异构磁性磁性磁性磁性磁性上的磁性磁力机械触发的磁性触发的磁性触发的磁性触发的磁性触发的磁性触发的磁性触发的磁性触发的磁性触发，并通过磁性磁力机械触发的Prestress进行转换。我们证明了两个物理概念的相互帮助 - 磁控制与形状记忆聚合物的热机械行为相结合，而无需新的材料合成和高功率能量才能重编程。我们的方法可以打开活跃的超材料，柔性但僵硬的机器人以及多模式变形结构的新路径，我们可以在其中以可逆和可重编程的方式设计它们。
Future active metamaterials for reconfigurable structural applications require fast, untethered, reversible, and reprogrammable (multimodal) transformability with shape locking. Herein, we aim to construct and demonstrate a magneto-thermomechanical tool that enables a single material system to transform with untethered, reversible, low-powered reprogrammable deformations and shape locking via the application of magneto-thermomechanically triggered prestress on a shape memory polymer and structural instability with asymmetric magnetic torque. We demonstrate the mutual assistance of two physics concepts - magnetic control combined with the thermomechanical behavior of shape memory polymers, without requiring new materials synthesis and high-power energy for reprogramming. Our approach can open a new path of active metamaterials, flexible yet stiff soft robots, and multimodal morphing structures, where we can design them in reversible and reprogrammable ways.
