Stretchable electronics has emerged over the past decade and is now expected to bring form factor‐free innovation in the next‐generation electronic devices. Stretchable devices have evolved with the synthesis of new soft materials and new device architectures that require significant deformability while maintaining the high device performance of the conventional rigid devices. As the mismatch in the mechanical stiffness between materials, layers, and device units is the major challenge for stretchable electronics, interface control in varying scales determines the device characteristics and the level of stretchability. This article reviews the recent advances in interface control for stretchable electronic devices. It summarizes the design principles and covers the representative approaches for solving the technological issues related to interfaces at different scales: i) nano‐ and microscale interfaces between materials, ii) mesoscale interfaces between layers or microstructures, and iii) macroscale interfaces between unit devices, substrates, or electrical connections. The last section discusses the current issues and future challenges of the interfaces for stretchable devices.

可拉伸电子设备的界面设计

可拉伸电子产品在过去十年中出现，现在有望为下一代电子设备带来无形状因素的创新。可拉伸器件随着新软材料和新器件架构的合成而不断发展，这些材料需要显着的变形能力，同时保持传统刚性器件的高器件性能。由于材料、层和设备单元之间机械刚度的不匹配是可拉伸电子产品的主要挑战，不同尺度的界面控制决定了设备特性和可拉伸水平。本文回顾了可拉伸电子设备界面控制的最新进展。它总结了设计原则，并涵盖了解决与不同尺度的界面相关的技术问题的代表性方法：i）材料之间的纳米和微米尺度界面，ii）层或微观结构之间的介观尺度界面，以及iii）单元器件之间的宏观尺度界面，基板或电气连接。最后一节讨论可拉伸设备接口的当前问题和未来挑战。
