Soft actuators with the capability to generate programmable and reconfigurable motions without the use of complicated and rigid infrastructures are of great interest for the development of smart, interactive, and adaptive soft electronic systems. Here, we report a new strategy to achieve a transparent and reconfigurable actuator by using a dielectric elastomer actuator (DEA), which provides mechanical strains under electrical bias, integrated with origami ethyl cellulose (EC) paper that “instructs” the shape changes of the actuator. The actuator can be reconfigured and multiple mechanical motions can be programmed in the device by creating crease patterns that induce variations in the local stiffness to direct the actuations. With the versatile design and fabrication approach, a light emission device with dynamic shape changes was demonstrated.

在不使用复杂而僵化的基础结构的情况下，能够产生可编程和可重新配置运动的软致动器对于智能，交互式和自适应软电子系统的开发非常感兴趣。在这里，我们报告一种通过使用介电弹性体致动器（DEA）来实现透明且可重新配置的致动器的新策略，该介电体致动器在电偏压下提供机械应变，并与折纸乙基纤维素（EC）纸集成在一起，从而“指示”绝缘纸的形状变化执行器。可以通过创建折痕图案来对致动器进行重新配置，并可以在设备中对多种机械运动进行编程，这些折痕会引起局部刚度的变化以指导致动。通过通用的设计和制造方法，演示了具有动态形状变化的发光器件。
