增塑聚氯乙烯（PVC）凝胶基软致动器在空气中响应快、变形大、电场下功耗低，作为新型软致动器显示出巨大的应用潜力。在我们以前的研究中，我们已经开发了一种多层膨胀和收缩型致动器，使用PVC凝胶和不锈钢网格电极。然而，使用刚性金属电极的致动器带来了显著的重量和尺寸、柔性和性能方面的限制的挑战。在这项研究中，为了开发具有更高性能和灵活性的致动器，我们提出了一种使用PVC凝胶和柔性电极的新型片状致动器。我们解释了所提出的片状致动器的驱动机制，并研究了不同增塑剂含量和膜厚度的致动器的基本特性。此外，我们还对所提出的PVC凝胶片驱动器和传统的电介质弹性体驱动器进行了对比实验，发现PVC凝胶片驱动器具有正电势，可以在较低的直流电场下驱动，从而获得比传统电介质弹性体驱动器更大的变形和更快的响应。并通过理论模型讨论了两种驱动器之间的差异，与实验结果吻合较好。
The plasticized polyvinyl chloride (PVC) gel-based soft actuator exhibits a fast response in air, large deformation, and low power consumption under an electrical field, so it shows great potential for use as a new type of soft actuator. In our previous study, we have developed a multilayered expansion and contraction-type actuator using PVC gel and stainless mesh electrodes. However, the actuator using rigid metal electrodes bring challenges of a notable weight and size, a limitation in flexibility and performance. In this study, to develop an actuator with higher performance and flexibility, we proposed a novel sheet actuator using PVC gel and flexible electrodes. We explain the driving mechanism of the proposed sheet actuator and investigate the basic characteristics of the actuators with different content of plasticizer and membrane thickness. Besides, we conducted a comparison experiment between the proposed PVC gel sheet actuator and the traditional dielectric elastomer actuator, founding that, the PVC gel sheet actuator had a positive potential to be driven at a lower DC field to get a bigger deformation and a faster response than those of the traditional dielectric elastomer actuator. And we discussed the difference between the two types of actuators with a theoretical model, finding a good agreement with the experimental results.
