Flexible and stretchable electrodes for dielectric elastomer actuators (2012, background): “Several research groups have attempted to disperse nano particles (titanium dioxide, BaTiO3) or dipole molecules into silicones in order to increase the permittivity of the elastomer [97–99].”
Increasing the performance of dielectric elastomer actuators: A review from the materials perspective (2015, background): “% of rutile-type TiO2 to a silicone rubber improved its dielectric properties while reducing its Young’s modulus [78].”
Fundamentals, processes and applications of high-permittivity polymer–matrix composites (2012, background): “In fact, recent works show that the improvement of dielectric permittivity is not the sole method to acquire a large electromechanical strain [86] and high electric energy storage density [269].”
Folded dielectric elastomer actuators (2007, background): “According to previous investigations, this material enables high active strains at relatively low fields [13, 15].”
Helical dielectric elastomer actuators (2005, methodology): “to studies we have performed [18, 19], following the work of Zhang et al [20], the permittivity of a dielectric elastomer (on which the material’s electromechanical response proportionally depends) can be increased at great advantage, by loading the material with highly dielectric ceramics.”
Electroactive polymer-based devices for e-textiles in biomedicine (2005, unknown): “For instance, by dispersing 30 wt% titanium dioxide powder into a silicone matrix, a driving field reduction of more than 1/3 and 1/4 has been obtained for the generated strain and stress, respectively [101].”
Standards for dielectric elastomer transducers (2015, background): “In practice, measurements are recommended only when the length/force variation over time is lower than 5% at least.”
