Drawing upon the strong application potential of mechanical hand claws, we have designed a dual-responsive hand claw structured by a photothermal double layer based on poly(N-isopropylacrylamide) and carbon nanotubes. By harnessing the photothermal conversion effect of carbon nanotubes on the hydrogel surface, the hydrogel reversibly absorbs and drains water, thus realizing the basic function of the hand claw. In addition, the integration of the magnetic material with the flexible robot, with the help of magnetic field actuation, effectively improves the mobility and flexibility of the hand claw and makes up for some of the shortcomings of traditional flexible robots. The enhancement of performance through optical-magnetic coupling will provide some valuable insights for the research of underwater microrobots.

基于聚（N-异丙基丙烯酰胺）和碳纳米管的光热双层结构的强大双响应手爪

借鉴机械手爪强大的应用潜力，我们设计了一种基于聚（N-异丙基丙烯酰胺）和碳纳米管的光热双层结构的双响应手爪。利用碳纳米管在水凝胶表面的光热转换效应，使水凝胶可逆地吸水和排水，从而实现手爪的基本功能。此外，磁性材料与柔性机器人的融合，借助磁场驱动，有效提高了手爪的机动性和灵活性，弥补了传统柔性机器人的一些缺点。通过光磁耦合增强性能将为水下微型机器人的研究提供一些有价值的见解。
