Molecular Strategies for Improved Dielectric Elastomer Electrical Breakdown Strengths [PDF]
Macromolecular Rapid Communications, 2018 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 ...
