Textile-based wearable electronics have attracted intensive research interest due to their excellent flexibility and breathability inherent in the unique three-dimensional porous structures. However, one of the challenges lies in achieving highly conductive patterns with high precision and robustness without sacrificing the wearing comfort. Herein, we developed a universal and robust in-textile photolithography strategy for precise and uniform metal patterning on porous textile architectures. The as-fabricated metal patterns realized a high precision of sub-100 µm with desirable mechanical stability, washability, and permeability. Moreover, such controllable coating permeated inside the textile scaffold contributes to the significant performance enhancement of miniaturized devices and electronics integration through both sides of the textiles. As a proof-of-concept, a fully integrated in-textiles system for multiplexed sweat sensing was demonstrated. The proposed method opens up new possibilities for constructing multifunctional textile-based flexible electronics with reliable performance and wearing comfort.
基于纺织品的可穿戴电子设备因其独特的三维多孔结构所固有的优异柔韧性和透气性而引起了广泛的研究兴趣。然而，挑战之一在于在不牺牲穿着舒适度的情况下实现高精度和高稳健性的高导电图案。在此，我们开发了一种通用且稳健的织物内光刻策略，用于在多孔纺织品结构上进行精确且均匀的金属图案化。所制备的金属图案实现了低于100 µm的高精度，同时具有理想的机械稳定性、可洗涤性和透气性。此外，这种可控涂层渗透到织物支架内部，通过织物的两面有助于显著提高小型化设备和电子集成的性能。作为概念验证，展示了一种用于多路汗液传感的完全集成的织物内系统。所提出的方法为构建具有可靠性能和穿着舒适度的多功能基于纺织品的柔性电子设备开辟了新的可能性。
