Stretchable electronics require sophisticated fabrication strategies to achieve both high electrical performance and mechanical compliance. While various approaches exist, from geometric designs to composite materials, most face challenges in balancing fabrication complexity with device performance. Here, we present a multilayer template stripping approach for fabricating stretchable conductors. This method combines the precision and scalability of template-based fabrication with the simplicity of transfer printing to create engineered microwire networks. Through systematic investigation of geometric parameters, we establish design rules for optimizing mechanical resilience of microwire arrays. We demonstrate both high-performance designs achieving 100% stretchability and robust architectures tolerant to fabrication variations, while maintaining low electrical resistance. The process is compatible with various metals and enables rapid, large-area fabrication, offering a practical route toward scalable manufacturing of stretchable conductors.
可拉伸电子器件需要复杂的制造策略来实现高电气性能和机械柔顺性。虽然存在各种方法，从几何设计到复合材料，但大多数方法在平衡制造复杂性与器件性能方面面临挑战。在此，我们提出一种用于制造可拉伸导体的多层模板剥离方法。该方法将基于模板制造的精度和可扩展性与转印印刷的简易性相结合，以创建工程化微线网络。通过对几何参数的系统研究，我们建立了优化微线阵列机械弹性的设计规则。我们展示了既能实现100%拉伸性的高性能设计，又有能耐受制造变化的稳健架构，同时保持低电阻。该工艺与各种金属兼容，能够实现快速、大面积制造，为可拉伸导体的可扩展制造提供了一条实用途径。
