Notes:
The acrylic acid and silicone are common dielectric elastomer materials. These actuatorshave shown excellent activate properties including large strains up to 380% and high energy densitiesup to 3.4 J/g, high efficiency, high responsive speed , good reliability and durability, etc. When avoltage is applied on the compliant electrodes of the dielectric elastomers, the polymer shrinks alongwith the electric field and expands in the plain area which erects the orientation of the line. In thispaper, we synthesize a novel silicone dielectric elastomer with high dielectric constant, large strainand high force output. Pre-strain and certain driving electric field are applied on the novel siliconefilm, respectively. The strain responsing to the Maxwell stress is measured. Using the largedeformation theory of finite element method to simulate the deformable behavior of materials, thesimulation results agree with the experiment. The coupling effect of the mechanics and electric fieldsapplied on the electrode of the dielectric elastomers is inverstigated. The finite element simulation oflarge deformation theory can be used to describe the dielectric elastomers materials large deformationthat induced by the static electric field
