Highly packable and deployable electronics offer a variety of advantages in electronics and robotics by facilitating spatial efficiency. These electronics must endure extreme folding during packaging and tension to maintain a rigid structure in the deployment state. Here, we present foldable and robustly deployable electronics inspired by Plantago, characterized by their tolerance to folding and tension due to integration of tough veins within thin leaf. The primary design approach for these electronics involves a high resistance to folding and tension, achieved through a thin multilayered electronic composite, which manages the neutral axis and incorporates tough Kevlar. The fabricated electronics can be folded up to 750,000 times without malfunctions and endure pulling an object 6667 times heavier than itself without stretching. Such robust electronics can be used as a deployable robot with sensor arrays, demonstrating practical applicability, as it maintains their mechanical and electrical properties during inflation from the packaged state.
高度可折叠和可展开的电子产品通过提高空间效率，在电子学和机器人技术领域具有多种优势。这些电子产品在包装过程中必须承受极度折叠，并能承受拉力，以在展开状态下保持刚性结构。在此，我们展示了受车前草启发的可折叠且能稳固展开的电子产品，其特点是由于在薄叶片中集成了坚韧的叶脉，使其能够耐受折叠和拉力。这些电子产品的主要设计方法包括通过一种薄的多层电子复合材料实现对折叠和拉力的高抗性，该复合材料能管理中性轴并融入坚韧的凯夫拉尔纤维。制造出的电子产品可折叠多达750,000次而无故障，并且能承受拉动比自身重6667倍的物体而不拉伸。这种坚固的电子产品可用作带有传感器阵列的可展开机器人，展示了其实际应用价值，因为它在从包装状态展开过程中能保持其机械和电气性能。
