电活性聚合物（EAP）具有在电场刺激下经历大变形的能力。它们在各种应用中提供了新的设计可能性，例如简单的柔软和灵活的致动器，可拉伸传感器和能量采集器。在介电弹性体的子类中，操作原理依赖于使软聚合物变形的带电电极之间的库仑力。由于力取决于电介质的介电常数，因此添加具有高介电常数的填料颗粒是增加整体机电耦合的有希望的方法。本文介绍了使用填充钡钛颗粒的硅树脂Elastosil P 7670 TM进行的各种机械和机电实验的结果。这些实验是在这样一种方式，所获得的结果是非常适合识别的必要材料参数的电粘弹性建模方法在第二部分的贡献（Mehnert等人提交）。
Electro-active polymers (EAPs) have the ability to undergo large deformations upon the stimulation by an electric field. They offer new design possibilities in a variety of applications, such as simple soft and flexible actuators, stretchable sensors, and energy harvesters. In the subclass of dielectric elastomers, the operation principle relies on the Coulomb forces between charged electrodes that deform the soft polymer. As the forces are dependent on the permittivity of the dielectric, the addition of filler particles with a high permittivity is a promising approach to increase the overall electro-mechanical coupling. This contribution presents the results of various mechanical and electro-mechanical experiments conducted with the silicone Elastosil P 7670 TM filled with Barium-Titanate particles. These experiments are performed in such a fashion that the obtained results are well suited for the identification of the necessary material parameters of an electro-viscoelastic modeling approach in Part II of this contribution (Mehnert et al. Submitted).
