To achieve adhesive and conformable wearable electronics, improving stretchable transparent electrode (STE) becomes an indispensable bottleneck needed to be addressed. Here, we adopt a nonuniform Young’s modulus structure with silver nanowire (AgNW) and fabricate a STE layer. This layer possesses transparency of >88% over a wide spectrum range of 400–1000 nm, sheet resistance below 20 Ω sq⁻¹, stretchability of up to 100%, enhanced mechanical robustness, low surface roughness, and good interfacial wettability for solution process. As a result of all these properties, the STE enables the fabrication of a highly efficient ultraflexible wearable device comprising of both organic photovoltaic (OPV) and organic photodetector (OPD) parts with high mechanical durability and conformability, for energy-harvesting and biomedical-sensing applications, respectively. This demonstrates the great potential of the integration of OPVs and OPDs, capable of harvesting energy independently for biomedical applications, paving the way to a future of independent conformable wearable OPV/OPDs for different applications.

为了实现粘性和可贴合的可穿戴电子产品，改进可拉伸透明电极 (STE) 成为需要解决的不可或缺的瓶颈。在这里，我们采用具有银纳米线 (AgNW) 的非均匀杨氏模量结构并制造 STE 层。该层在 400-1000 nm 的宽光谱范围内具有 >88% 的透明度，薄层电阻低于 20 Ω sq ^-1, 可拉伸性高达 100%，增强的机械强度，低表面粗糙度和良好的界面润湿性，适用于溶液工艺。由于所有这些特性，STE 能够制造高效的超柔性可穿戴设备，包括具有高机械耐久性和一致性的有机光伏 (OPV) 和有机光电探测器 (OPD) 部件，用于能量收集和生物医学传感应用程序，分别。这证明了 OPV 和 OPD 集成的巨大潜力，能够独立地为生物医学应用收集能量，为未来用于不同应用的独立贴合可穿戴 OPV/OPD 铺平了道路。
