传统的平面气动致动器由于不可避免地连接到其上的管和泵而不能充分利用其薄、轻和柔性的性质。在这篇文章中，我们建立在我们以前的工作，并提出液体袋电机，一个家庭的可打印的软致动器，包括一个或多个气密囊（称为袋）充满低沸点液体。当超过34摄氏度的热量施加到它们上时，袋内的液体蒸发，整个结构膨胀。特别是，我们新提出的卷到卷的大规模生产的液体袋电机与矩形形状的因素，除了以前报告的数控热拉伸。讨论了驱动器的材料选择和所需的液体体积。基于这种制造过程，我们评估了所提出的致动器的机械性能。通过利用致动器的优势，我们实现了三种形状改变界面：（1）与印刷纸电路相结合的电驱动可印刷纸机器人;（2）通过环境热量被动致动的无束缚建筑立面;以及（3）通过入射光和体温改变颜色和纹理的衣服。我们相信，液体袋电机将作为一个新的工具箱，用于制造和应用的软致动器在互动的情况下。
Conventional planar pneumatic actuators have not been able to make the most of their thin, lightweight, and flexible nature due to tubes and pumps inevitably connected to them. In this article, we build upon our prior work and propose Liquid Pouch Motors, a family of printable soft actuators that consist of one or more gas-tight bladders (called pouches) filled with low boiling point liquid. When the heat over 34 degrees C is applied to them, the liquid inside the pouch evaporates and the whole structure inflates. Especially, we newly presented roll-to-roll mass production of Liquid Pouch Motors with the rectangular form factor in addition to the previously reported CNC heat drawing. We also discussed the suitable material selection and the volume of liquid needed for the actuators. Based on this fabrication procedure, we evaluated the mechanical properties of the proposed actuators. By leveraging the benefits of the actuators, we then implemented three shape-changing interfaces: (1) electrically driven printable paper robots combined with printed paper circuit; (2) an untethered architecture facade that passively actuates by ambient heat; and (3) dresses that change their color and texture by the incident light and the body temperature. We believe that Liquid Pouch Motors will work as a new toolbox for the fabrication and application of soft actuators in interactive scenarios.
