Art and science represent human creativity and rational thinking, respectively. When the two seemingly opposite fields are intertwined, there is always a life-changing spark. In particular, the integration of ancient traditional Chinese art into the latest electronic devices is always been an unexcavated topic. Fabricating two-dimensional material with a tensile strain less than 3% with an ultimate global stretch has been an important problem that plagues the current flexible electronics field. The current research is limited to material in small scale, and it is always necessary to develop and extend large-sized flexible electronic systems. Here, inspired by the traditional Chinese paper-cut structure, we present a highly deformable multifunctional electronic system based on the MoS nanosheet. In this work, we first demonstrate how the traditional paper-cut structure can open the view of flexible electronics. In order to obtain a large area of MoS with excellent performance, we use a metal-assisted exfoliation method to transfer MoS, followed by fabricating a field effect transistor to characterize its excellent electrical properties. Two photodetectors and a temperature sensor are produced with good performance. The mechanical simulation proves that the structure has more advantages in stretchability than other typical paper-cut structures. From the experimental and mechanical point of view, it is proved that the device can work stably under high deformation. We finally show that the device has broad application prospects in highly deformed organs, tissues, and joints. These findings set a good example of traditional Chinese culture to guide innovation in the field of electronic devices.
艺术和科学分别代表了人类的创造力和理性思维。当这两个看似对立的领域相互交织时，总会产生改变生活的火花。特别是，将古老的中国传统艺术融入最新的电子设备一直是一个未被挖掘的话题。制造具有小于3%拉伸应变且具有最终全局拉伸的二维材料一直是困扰当前柔性电子领域的一个重要问题。目前的研究仅限于小规模材料，开发和扩展大型柔性电子系统总是很有必要的。在此，受中国传统剪纸结构的启发，我们展示了一种基于MoS纳米片的高度可变形多功能电子系统。在这项工作中，我们首先展示了传统剪纸结构如何开启柔性电子的视野。为了获得大面积性能优异的MoS，我们采用金属辅助剥离法转移MoS，随后制造场效应晶体管以表征其优异的电学性能。制作出了两个性能良好的光电探测器和一个温度传感器。力学模拟证明该结构在拉伸性方面比其他典型剪纸结构更具优势。从实验和力学角度证明，该器件在高变形下能稳定工作。我们最终表明该器件在高度变形的器官、组织和关节中具有广阔的应用前景。这些发现为中国传统文化树立了一个很好的榜样，以指导电子设备领域的创新。
