Molecular Strategies for Improved Dielectric Elastomer Electrical Breakdown Strengths [PDF]
AbstractDielectric elastomer transducers (actuators and generators) possess great commercial potential because they allow for novel transducer designs and applications due to—amongst others—their flexibility and low weight. On the other hand, the flexibility and inherent softness of dielectric elastomers also pose restrictions on their use, since the ...

Thickness-dependence of the breakdown strength: Analysis of the dielectric and mechanical failure [PDF]
The breakdown strength as well as the mechanical strength of ceramic materials decreases with increasing volume. The volume-effect of the mechanical strength can be explained by the Weibull theory. For the breakdown strength the same explanation has been often assumed.
