ENHANCING THE DIELECTRIC PERMITTIVITY OF ELASTOMERS
, 2008 The electromechanical transduction properties of any dielectric elastomer are intrinsically regulated by the dielectric permittivity of the material. This parameter proportionally controls both the achievable active stresses and strains. Accordingly, a suitable increase of the material permittivity may provide a valuable means to improve the ...

Dynamic response of dielectric elastomers
International Journal of Non-Linear Mechanics, 2004Dielectric elastomers have received a great deal of attention recently for effectively transforming electrical energy to mechanical work. Their large strains and conformability make them enticing materials for many new types of actuators. Unfortunately, their non-linear material behavior and large deformations make actual devices difficult to model ...

ABSTRACT Life shows us that the distri bution of intellig ence throughout flexible muscular ne tworks is a highly successful solution to a wide range of challenges, for example: human hearts, octopi, or even starfish. Recreating this success in engineered systems requires soft actuator technologies with embedded sensing and intelligence.
