Active Elastomer Components Based on Dielectric Elastomers
International Polymer Science and Technology, 2015A new design concept developed at the Fraunhofer LBF allows dielectric elastomers to be integrated efficiently as load-bearing components, serving as both actuator and sensor at the same time. Since the concept is based on perforated metal electrodes with high electrical conductivities, it can also be used for highly dynamic and acoustic applications ...
