There are several obstacles currently limiting the use of dielectric elastomers in actuators and energy generators, ranging from too large mechanical losses to high voltages needed for actuation. Acrylic elastomers, natural and synthetic rubbers and polydimethylsiloxane PDMS are interesting materials for the next generation of dielectric elastomer transducer materials.
Most important results
In order to be independent of novel materials in the beginning phase of the project, the two groups agreed that work at the Johannes Kepler University will also focus on fundamental problems of dielectric elastomer transducers, avoiding electromechanical instabilities during operation and seeking strategies to make the materials long term stable. In addition the materials base was widened to include natural rubber.
