This work contextualizes the research of materials that can be applied as artificial muscles. The main motivation of this research is the importance of the development of mechatronic systems for the replacement of traditional devices of actuation and motion based on rotational electrical motors by other devices that reproduce biological muscle movements. Electroactive polymers (EAPs) are materials that respond to electric stimuli with shape and/or dimension changes, and accomplish movements that are smooth enough to mimic biological muscles. Among EAPs, the ionomeric polymer-metal composites (IPMCs) are an interesting alternative to biomimetic devices due to large displacements when submitted to low applied voltage. This article presents a brief review of IPMCs, a sample preparation procedure, and some electromechanical experimental results. We also discuss the applicability of this technology in medical devices and as artificial muscles.
本文将材料的研究置于人工肌肉的应用背景下。这项研究的主要动机是开发机电系统的重要性，以取代基于旋转电机的传统致动和运动设备，转而采用其他能够再现生物肌肉运动的设备。电活性聚合物（EAP）是一种对电刺激做出响应并产生形状和/或尺寸变化的材料，其运动足够平滑，可以模拟生物肌肉。在 EAP 中，离子聚合物-金属复合材料（IPMC）是仿生设备的一个有趣选择，因为在施加低电压时会产生较大的位移。本文简要回顾了 IPMC，介绍了一种样品制备程序，并给出了一些机电实验结果。我们还讨论了这项技术在医疗器械和人工肌肉中的适用性。
