Recently, origami (ancient arts of paper folding) is becoming a popular tool to design mechanical metamaterials. This overview summarizes an EML webinar on Nov. 4th, 2021. It covers some demonstrations of rigid origami-based foldable electronics, kirigami (i.e., paper cutting) based stretchable electronics, microscale origami, and deformable origami-based mechanical metamaterials. The author hopes that this overview and the EML webinar (https://imechanica.org/node/25538) may provide new opportunities to the mechanics community to future explore the interesting properties of origami-based mechanical metamaterials with unique functionalities.

最近，折纸（古老的折纸艺术）正成为设计机械超材料的流行工具。本概述总结了 2021 年 11 月 4 日举行的 EML 网络研讨会。它涵盖了基于刚性折纸的可折叠电子设备、基于剪纸（即剪纸）的可拉伸电子设备、微型折纸和基于可变形折纸的机械超材料的一些演示。作者希望这个概述和 EML 网络研讨会 (https://imechanica.org/node/25538) 可以为力学界提供新的机会，以在未来探索具有独特功能的基于折纸的机械超材料的有趣特性。EML 网络研讨会演讲者和视频在 https://imechanica.org/node/24098 上更新。
