力学超材料是一种有别于传统力学行为的工程材料，它源于人工可编程的微结构以及材料的固有属性。在过去的十年中，随着计算性能和复杂微观结构制造能力的巨大进步，力学超材料已经吸引了研究人员的广泛关注，因为它能够实现自然界中不可能出现的多重物理属性。该领域迅速崛起的趋势之一是将材料行为和单元结构与其他不同的多种物理因素(如电场或磁场)以及温度、光或化学反应等刺激相结合，从而扩大按需主动调制力学响应的范围。在本文中，我们旨在概述有关超材料的力学和多物理性质调制的相关文献，重点介绍双能级设计的新兴趋势，着重讨论力学超材料在关键工程领域应用中的巨大潜力。本文对该领域的发展趋势、挑战和未来路线进行了系统深入分析，涵盖实时可重构性和功能编程、4D打印、纳米超材料、人工智能和机器学习、多物理折纸/剪纸、活性物质、软物质和保形超材料、复杂微结构制造、服役寿命效应和可扩展性等概念。
