用于可穿戴应用的超柔性皮肤相容有机光电子器件

摘要：

超高贴合性的有机光电器件正逐渐成为新一代可穿戴与生物医学技术的重要平台。其内在的机械柔软性以及对大面积、低温制备工艺的良好兼容性，使其能够与人体实现高度贴合、无缝集成。这些特性使其在皮肤附着式传感器、柔性能量采集器以及生物界面系统等应用中展现出显著优势。

然而，在反复形变条件下同时实现长期机械耐久性与稳定的电学和光学性能，仍然是该领域面临的关键挑战。本研究展示了近年来在材料体系与器件结构设计方面取得的最新进展，以应对这一难题。相关策略包括可拉伸半导体与导电高分子材料的开发，以及通过力学自适应的多层结构设计来有效缓解应变集中问题。

实验结果表明，这些器件在弯曲、拉伸和扭转等动态机械应力条件下，仍能保持良好的功能稳定性。其功能价值进一步通过在实时生理信号监测、运动追踪以及人机交互系统中的应用得以验证。上述研究加深了对柔性体系中力学–电子耦合机制的理解，并为未来体表集成电子器件的设计提供了具有实践意义的指导原则。

Title

Ultra-flexible skin-compatible organic optoelectronics for wearable application

Abstract：

Ultra-conformable organic optoelectronic devices are emerging as promising platforms for next-generation wearable and biomedical technologies. Their intrinsic mechanical softness and compatibility with large-area, low-temperature fabrication techniques enable seamless integration with the human body. These features make them ideal candidates for applications such as skin-attachable sensors, soft energy harvesters, and bio-interfacing systems. However, a key challenge remains in achieving long-term mechanical durability while maintaining stable electronic and optical performance under repeated deformation. This work presents recent advances in materials and device architectures that address this challenge. Strategies include the development of stretchable semiconducting and conducting polymers, as well as mechanically adaptive multilayer structures that mitigate strain concentration. Experimental results demonstrate that these systems retain functional stability under dynamic mechanical stress, including bending, stretching, and torsion. The functional relevance of these devices is further validated through their application in real-time physiological monitoring, motion tracking, and human–machine interfaces. The findings contribute to a deeper understanding of the mechanical-electronic coupling in soft systems and offer practical design principles for future body-integrated electronics.
