具有柔性大变形的离子聚合物-金属复合材料作为仿生致动器和传感器在各个领域得到了广泛的应用。这项工作主要集中在各种离子聚合物金属复合材料的应用，如一个领域需要一个大的合力，大尖端偏转，或高响应频率所提出的理论预测的验证。这种性能可以通过多层离子聚合物金属复合致动器的层数和厚度比来控制。因此，我们认为主要的设计因素，如层数和厚度比在分析中提出的理论模型和进行实验，以验证静态和动态的机电响应的多层（多晶型）离子聚合物金属复合结构作为致动器。聚合物（Nafion）与电极或基底之间的关系用β表示。从这个理论分析，三个属性进行了分析和预测的基础上的欧拉-伯努利梁理论，考虑到离子聚合物金属复合材料，电极，和粘合层（基板层）的动力学。一个对称的离子聚合物金属复合材料多晶型的预测结果进行了比较，有限元分析和实验使用离子聚合物金属复合材料多晶型与一至五层的结果。最后，本文研究了层数和厚度如何影响动态特性。这有助于预测和优化设计多层离子聚合物金属复合材料致动器，以满足特定的要求。
Ionic polymer metal composites with a flexible large deformation have been used as biomimetic actuators and sensors in various fields. This work mainly focuses on the validation of the proposed theoretical prediction for various ionic polymer metal composite applications, such as a field needing a large resultant force, large tip deflection, or high response frequency. Such properties can be controlled by the number of layers and the thickness ratio of a multilayered ionic polymer metal composite actuator. Thus, we considered major design factors such as the number of layers and the thickness ratio in analysis of the proposed theoretical model and performed experiments to verify the static and dynamic electromechanical responses of multilayered (multimorph) ionic polymer metal composite structures acting as actuators. The relation between the polymer (Nafion) and electrode or substrate is represented by β. From this theoretical analysis, three properties were analyzed and predicted based on the Euler–Bernoulli beam theory, considering the dynamics of the ionic polymer metal composite, electrode, and bonding layers (substrate layers). The predicted results of a symmetric ionic polymer metal composite multimorph were compared with results of finite element analysis and experiments using ionic polymer metal composite multimorphs with one to five layers. Finally, this work examined how the number of layers and thickness affect the dynamic properties. This can contribute to predicting and optimally designing a multilayered ionic polymer metal composite actuator for satisfying a specific requirement.
