Photoactuated pens have emerged as promising tools for expedient, mask-free, and versatile nanomanufacturing. However, the challenge of effectively controlling individual pens in large arrays for high-throughput patterning has been a significant hurdle. In this study, we introduce novel generations of photoactuated pens and explore the impact of pen architecture on photoactuation efficiency and crosstalk through simulations and experiments. By introducing a thermal insulating layer and incorporating an air ap in the architecture design, we have achieved the separation of pens into independent units. This new design allowed for improved control over the actuation behavior of individual pens, markedly reducing the influence of neighboring pens. The results of our research suggest novel applications of photoactive composite films as advanced actuators across diverse fields, including lithography, adaptive optics, and soft robotics.
光驱动笔已成为用于便捷、无需掩膜且通用的纳米制造的有前景的工具。然而，在大型阵列中有效控制单个笔以实现高通量图案化的挑战一直是一个重大障碍。在本研究中，我们引入了新一代光驱动笔，并通过模拟和实验探索笔的结构对光驱动效率和串扰的影响。通过在结构设计中引入隔热层并合并空气间隙，我们实现了将笔分离为独立单元。这种新设计使得对单个笔的驱动行为有了更好的控制，显著降低了相邻笔的影响。我们的研究结果表明，光活性复合膜作为先进的致动器在包括光刻、自适应光学和软机器人技术等不同领域有新的应用。
