与刚性致动器相比，软聚合物致动器在致动时具有更像流体的运动和柔性，因此需求不断增加，这使得它们在各种工程应用中具有价值。软聚合物致动器的主要类型之一是介电弹性体致动器，其工作原理是在电极之间施加电压电势差，以减小弹性体材料的厚度，同时扩大其面积。本文着眼于利用双光子聚合3D打印制造微型软聚合物介电弹性体致动器。该致动器包含微通道，该微通道通过使用毛细管作用填充有电极。一个复杂的螺旋几何形状的设计，印刷，并测试电极填充能力。本文中描述了相当多的障碍，包括使用新发布的双光子聚合树脂，其具有有限的支持资源，以及具有大顺应性的复杂螺旋几何形状，其制造、后处理、处理、电极填充、电极集成和致动测试大大复杂化。然而，通过使用目前可用于树脂的标准印刷配方，添加电极隔离层，以及印刷更厚的弹性体区域以获得更多的结构支撑，这些挑战得以克服。研究结果为微通道内电极的毛细管填充方法奠定了基础，并为多功能微软致动器的研制奠定了基础。
Soft polymer actuators are in increasing demand due to their more fluid like motion and flexibility when actuated than compared with rigid actuators, which makes them valuable in diverse engineering applications. One of the main types of soft polymer actuators is the dielectric elastomer actuator, whose working principle is to apply a voltage potential difference between electrodes to reduce the thickness of the elastomeric material while expanding its area. This paper looks at manufacturing a micro soft polymer dielectric elastomer actuator utilizing two-photon polymerization 3D printing. The actuator contains micro channels that are filled with an electrode by using capillary action. A complex helical geometry is designed, printed, and tested for electrode filling capabilities. Quite a few obstacles are described in this paper including the use of a newly released two-photon polymerization resin which has limited supporting resources, as well as the complex helical geometry having a large compliance that vastly complicates its fabrication, post-processing, handling, electrode filling, electrode integration, and actuation testing. However, these challenges are overcome by using the standard printing recipes currently available for the resins, adding electrode isolation layers, and printing thicker elastomer zones for more structural support. The results found solidify the approach of filling microchannels with electrodes through capillary action and lead to further the focus and creation of multi-functional micro soft actuators.
