Soft actuators have tremendous applications in diverse fields. Facile preparation, rapid actuation, and versatile actions are always pursued when developing new types of soft actuators. In this paper, we present a facile method integrating laser etching and mechanical cutting to prepare Janus actuators driven by oil. A Janus film with superhydrophobic and hydrophobic sides was fabricated successfully. By cutting the functional layer at the desired positions, a number of quintessential oil-driven soft devices were demonstrated. Furthermore, Janus actuators with surfaces of different wettabilities exhibited different swelling behaviors, and different media manifested different surface extensions; thus, these actuators are promising candidates for soft actuators and also realized on-off switchability between an oil/water mixture and ethanol. This study offers novel insight into the design of soft actuators, and this insight may be helpful for developing an oil-driven soft actuator that can be operated like a human finger to manipulate any object and extending stimuli-responsive applications for soft robotics.
软驱动器在多个领域有着广泛的应用。在开发新型软驱动器时，人们一直追求简便的制备方法、快速的驱动以及多样的动作。在本文中，我们提出了一种将激光蚀刻和机械切割相结合的简便方法来制备由油驱动的双面驱动器。成功制备了具有超疏水和疏水两面的双面薄膜。通过在所需位置切割功能层，展示了许多典型的油驱动软器件。此外，具有不同润湿性表面的双面驱动器表现出不同的溶胀行为，不同的介质表现出不同的表面延伸；因此，这些驱动器有望成为软驱动器的候选者，并且还实现了油/水混合物和乙醇之间的通断切换。这项研究为软驱动器的设计提供了新的见解，这种见解可能有助于开发一种能像人类手指一样操作以操纵任何物体的油驱动软驱动器，并扩展软机器人的刺激响应应用。
