Abstract. Dielectric elastomer generator systems (DEGSs) are a class of electrostatic soft-transducers capable of converting oscillating mechanical power from different sources into usable electricity.
What is actuation strain?
ACTUATION STRAIN. ALL THE STRAIN WHICH IS NOT MECHANICAL, NOT DUE TO A MECHANICAL STRAIN. ACTUATION STRAIN DOES NOT NECESSARELY PRODUCE STRESSES.
How are electroactive polymers made?
Electret was formed by combining carnauba wax, rosin and beeswax, and then cooling the solution while it is subject to an applied DC electrical bias. The mixture would then solidify into a polymeric material that exhibited a piezoelectric effect.
How does a dielectric elastomer work?
Dielectric elastomers (DEs) are fundamentally a transducer technology, meaning they convert energy from one form to another. More specifically, DE devices are electromechanical transducers that convert electrical energy to mechanical energy. Transducers that convert electrical to mechanical energy are actuators.
What is an elastomer actuator?
ABSTRACT. Dielectric elastomer actuators (DEAs) are soft, electrically powered actuators that have no discrete moving parts, yet can exhibit large strains (10%–50%) and moderate stress (∼100 kPa).
What are fluidic actuators?
Abstract. Fluid actuated soft robots, or fluidic elastomer actuators, have shown great potential in robotic applications where large compliance and safe interaction are dominant concerns. In the proposed approach, a sealed elastic tube filled with fluid (gas or liquid) is segmented by adaptors.
What is dielectric elastomer actuators?
Dielectric elastomers actuators (DEA) are a class of electroactive polymers which work based on inducing of deformation with an electric field, which was demonstrated in 1880 by Wilhelm Conrad Roentgen by spraying charges on a piece of natural rubber (Röntgen 1880).
