表述电活性聚合物（EAP）用于共同描述显示出由于电场激发而经历大变形的能力的聚合物材料。这种能力使它们成为开发可用于机器人等领域的软致动器的有趣候选人。当使用介电弹性体时，这些类型的致动器通常由夹在一对顺应性电极之间的聚合物材料的薄膜组成。然而，这些电极影响聚合物的机械材料响应。出于这个原因，我们证明了在这方面的贡献的影响，顺应性电极的粘弹性材料的行为的聚合物材料，即VHB 4905（TM），使用实验数据和建模方法。
The expression electro-active polymers (EAPs) is used to collectively describe polymeric materials that show the ability to undergo large deformations due to the excitation by an electric field. This ability makes them interesting candidates in the development of soft actuators that can be used for example in robotics. When using dielectric elastomers these types of actuators usually consist of a thin film of polymeric material sandwiched between a pair of compliant electrodes. However these electrodes influence the mechanical material response of the polymer. For this reason we demonstrate in this contribution the influence of the compliant electrodes on the viscoelastic material behavior of a polymeric material, i.e. VHB4905 (TM), using both experimental data and a modelling approach.
