在本文中，我们提出了生物启发的智能结构，利用柔性离子聚合物复合材料的驱动和kirigami设计原理。Kirigami设计用于将平面致动器转换为能够进行大的平面外位移并复制生物机制的主动3D结构。在这里，我们提出了burstbot，基于房室尖瓣的流体控制和推进机制，和vortibot，基于Vorticella campanula，纤毛虫原生动物的螺旋致动器。来自生物对应物的模型被用作设计优化和致动器性能测量的平台。对称和非对称的流体相互作用的burstbot的调查和流体输送应用程序中的有效性证明。vortibot致动器在几何上被优化为能够360度扫描的相机定位器。单圈螺旋致动器的实验结果表明，复杂的驱动来自一个单一的自由度控制信号。
In this paper we present bio-inspired smart structures which exploit the actuation of flexible ionic polymer composites and the kirigami design principle. Kirigami design is used to convert planar actuators into active 3D structures capable of large out-of-plane displacement and that replicate biological mechanisms. Here we present the burstbot, a fluid control and propulsion mechanism based on the atrioventricular cuspid valve, and the vortibot, a spiral actuator based on Vorticella campanula, a ciliate protozoa. Models derived from biological counterparts are used as a platform for design optimization and actuator performance measurement. The symmetric and asymmetric fluid interactions of the burstbot are investigated and the effectiveness in fluid transport applications is demonstrated. The vortibot actuator is geometrically optimized as a camera positioner capable of 360 degrees scanning. Experimental results for a one-turn spiral actuator show complex actuation derived from a single degree of freedom control signal.
