将电子器件集成到皮肤、纺织品、生物组织等复杂形貌的表面，需要兼具机械顺应性、高性能和可规模化制造的制备策略。二维（2D）半导体是此类应用的理想材料，但将其集成到可延展电子系统仍具挑战：规模化液相加工制得的薄膜电子性能有限，而高质量化学气相沉积（CVD）材料则需要复杂的合成与转移工艺。本研究通过将高通量卷对卷机械剥离与商用临时纹身贴、水转印贴转移基底相结合，建立了基于半导体范德华材料的可规模化可延展电子器件制备路线。该方法可制备超薄MoS₂基电子器件，能转移至皮肤、合成皮革、植物叶片等粗糙曲面表面；转移后器件工作可靠，具备优异的电子与光电子性能，包括响应度达约3.5 A W⁻¹的光电探测器、温度电阻系数为每摄氏度-2至-3.5%的热敏电阻，以及迁移率达约18 cm² V⁻¹ s⁻¹的离子凝胶栅控场效应晶体管。
英文摘要
Integrating electronic devices onto surfaces with complex topography such as skin, textiles, and biological tissues requires fabrication strategies that combine mechanical conformability with high electronic performance and scalable manufacturing. While two-dimensional (2D) semiconductors are promising materials for such applications, their integration into conformal electronic systems remains challenging because scalable liquid-phase processing typically yields films with limited electronic performance, whereas high-quality CVD materials require complex synthesis and transfer processes. Here we establish a scalable route toward conformal electronics based on semiconducting van der Waals materials by combining high-throughput roll-to-roll mechanical exfoliation with commercially available temporary tattoo and waterslide decal transfer substrates. This approach enables the fabrication of ultrathin MoS2-based electronic devices that can be transferred onto rough and curved surfaces such as skin, synthetic leather, and plant leaves. The resulting devices operate reliably after transfer and exhibit strong electronic and optoelectronic performance, including photodetectors with responsivities up to approximately 3.5 A W$^{-1}$, thermistors with temperature coefficients of resistance from -2 to -3.5% per degree Celsius, and ionic-gel-gated field-effect transistors with mobilities reaching approximately 18 cm$^2$ V$^{-1}$ s$^{-1}$.
