Electro-active polymers (EAPs) have the ability to undergo large deformations upon the stimulation by an electric field. They offer new design possibilities\ud in a variety of applications, such as simple soft and flexible actuators, stretchable\ud sensors, and energy harvesters. In the subclass of dielectric elastomers, the operation\ud principle relies on the Coulomb forces between charged electrodes that deform the\ud 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\ud the overall electro-mechanical coupling. This contribution presents the results of\ud various mechanical and electro-mechanical experiments conducted with the silicone\ud Elastosil P 7670TM filled with Barium-Titanate particles. These experiments are performed in such a fashion that the obtained results are well suited for the identification\ud of the necessary material parameters of an electro-viscoelastic modelling approach\ud in Part II of this contribution (Mehnert et al. Submitted). |
