Two-dimensional (2D) materials such as graphene and molybdenum disulfide et al. offer significant new prospects for electronics, optics, and biosensing applications due to their unique physical and chemical properties. The controlled manipulation of such materials to create three-dimensional (3D) architectures is an intriguing approach to favorably tuning their properties and creating new types of 3D devices with small form factors. However, 2D materials exhibit extremely low bending stiffnesses compared with traditional functional materials, therefore, it is rather challenging to obtain stable 3D structures under van der Waals (vdW) interaction despite the easier out-of-plane manipulation. The centuries-old paper-shaping techniques named as ‘kirigami’ and ‘origami’ may provide a potential solution to this deadlock. The general idea is that through pre-patterning and mechanical deformations, 2D materials can be reshaped and transformed into 3D structures on demand, which extends the application of kirigami/origami from conventional functional films to atomically thin nanosheets. This kind of shaping and structuring strategy not only integrates 2D materials with 3D micro/nano-structures in a controllable manner, but also offers a new paradigm for tailoring the properties of 2D materials, thus enabling more functions beyond the capability of planar geometry. Such 3D micro/nano-architectures containing engineered 2D materials can provide a platform to explore the frontier physics and produce micro/nano-devices with improved performance or unprecedented functionalities. Hence, it is necessary to review the recent progress in this emerging field, which combines the exemplary kirigami/origami strategy with promising 2D materials to increasingly inspire the multidisciplinary applications. This review focuses on 2D materials kirigami/origami, including intrinsic and engineered properties, mechanisms, methods and applications. The research challenges and opportunities are also discussed to promote future theoretical and technological studies in this blooming interdisciplinary field.

二维（2D）材料，例如石墨烯和二硫化钼等。由于其独特的物理和化学特性，它们为电子，光学和生物传感应用提供了重要的新前景。对此类材料的受控处理以创建三维（3D）架构是一种有趣的方法，可以很好地调整其属性并创建具有小尺寸尺寸的新型3D设备。但是，与传统功能材料相比，2D材料显示出极低的弯曲刚度，因此，尽管更容易在平面外进行操作，但在范德华（vdW）相互作用下获得稳定的3D结构却颇具挑战。几百年来被称为“ kirigami”和“ origami”的纸张整形技术可能为这种僵局提供潜在的解决方案。总体思路是，通过预构图和机械变形，可以根据需要将2D材料重塑并转换为3D结构，从而将kirigami / origami的应用范围从常规功能膜扩展到原子薄的纳米片。这种成型和结构化策略不仅以可控的方式将2D材料与3D微观/纳米结构集成在一起，而且还为定制2D材料的特性提供了新的范例，从而实现了超出平面几何形状能力的更多功能。包含工程2D材料的此类3D微/纳米架构可以提供一个平台，以探索前沿物理学并生产出性能提高或功能空前的微/纳米设备。因此，有必要回顾一下这个新兴领域的最新进展，它结合了示例性的折纸/折纸策略和有前途的2D材料，从而日益激发了多学科应用。这篇综述着重于2D材料kirigami / origami，包括内在和工程特性，机制，方法和应用。还讨论了研究挑战和机遇，以促进这一新兴学科领域的未来理论和技术研究。
