离子聚合物是一种很有前途的材料，用于开发肌肉样致动器。这些材料在构造为金属-聚合物-金属复合片材时能够经历显著变形。这些薄片的机械特征，例如柔韧性、柔软性以及在与水直接接触时发生大变形的能力，使一些人认为这些可能是人造肌肉。本文描述了肌肉状聚合物变形的电化学模型的数值分析。一个通用的连续模型描述这些致动器的运输和变形过程中，简要介绍，沿着用于预测变形，电流和质量运输的模拟方案的详细描述。模型的预测与实验数据进行了比较，表明水的传输在大规模变形中的重要作用。该模型还用于比较天然肌肉和肌肉状聚合物致动器的性能。
Ionic polymers are a promising material for the development of muscle‐like actuators. These materials are capable of undergoing significant deformation when structured as metal‐polymer‐metal composite sheets. The mechanical characteristics of these sheets, such as flexibility, softness, and ability to undergo large deformation in direct contact with water, have led some to consider these as possible artificial muscles. This paper describes the numerical analysis of an electrochemical model of the deformation of muscle‐like polymers. A general continuum model describing the transport and deformation processes of these actuators is briefly presented, along with a detailed description of the simulation scheme used to predict deformation, current, and mass transport. The predictions of the model are compared with experimental data, indicating a significant role of water transport in the large‐scale deformation. The model is also used to draw a comparison between the performance of natural muscles and muscle‐like polymer actuators.
