柔性机械超材料是一种柔性结构，通过其部件的大变形来实现独特的性能。虽然它们的静态特性已经得到了广泛的研究，但其动态特性的研究仍处于早期阶段，特别是在其高变形引起的非线性区域。然而，最近的研究表明，这些系统提供了新的机会，大振幅弹性波的控制。在这里，我们总结了最近的结果，非线性波在柔性弹性超材料的传播，并强调可能的新的研究方向。
Flexible mechanical metamaterials are compliant structures engineered to achieve unique properties via the large deformation of their components. While their static character has been studied extensively, the study of their dynamic properties is still at an early stage, especially in the nonlinear regime induced by their high deformability. Nevertheless, recent studies show that these systems provide new opportunities for the control of large amplitude elastic waves. Here, we summarize the recent results on the propagation of nonlinear waves in flexible elastic metamaterials and highlight possible new research directions.
