Abstract

Silicone materials are very appropriate for dielectric elastomer (DE) transducer applications due to their distinguished mechanical and electrical characteristics like high elasticity and an efficient electromechanical behavior. Since the material parameter permittivity influences significantly the work output, Wacker Chemie AG developed a new silicone named ELASTOSIL® Film 5030 with increased permittivity for improving the work output. Within this contribution, the mechanical characteristics including the hyperelasticity and electromechanically coupled behavior is compared to standard silicone material ELASTOSIL® Film 2030 from Wacker Young’s modulus of both materials are obtained conducting tensile tests, while the electromechanical behavior is characterized by investigating a planar single layer DE transducer. The new material has a similar Young’s modulus compared to the standard material. Furthermore, the electrically actuated deformation of the planar single layer DE transducers made form new silicone is proportional larger to its permittivity and inversely proportional to its Young’s modulus under same electrical field applied.
