Effect of different prestretching index and preloading on actuation behaviors of dielectric elastomer actuator

Journal of Materials Research and Technology, 2021
Herein, the prestretching indexes of dielectric elastomers (DE) were determined by measuring the tensile properties, and then the actuation displacement and output force of the conical dielectric elastomer actuator (CDEA) with different prestretching ...

Styrenic-Rubber Dielectric Elastomer Actuator with Inherent Stiffness Compensation

Actuators, 2020
Up to date, Dielectric Elastomer Actuators (DEA) have been mostly based on either silicone or acrylic elastomers, whereas the potential of DEAs based on inexpensive, wide-spread natural and synthetic rubbers has been scarcely investigated. In this paper,

Geometry-based customization of bending modalities for 3D-printed soft pneumatic actuators [PDF]

, 2018
In this work, we propose a novel type of 3D-printed soft pneumatic actuator that allows geometry-based customization of bending modalities. While motion in the 3D-space has been achieved for several types of soft actuators, only 2D-bending has been ...

Effects of Thinner Compliant Electrodes on Self-Clearability of Dielectric Elastomer Actuators

Actuators, 2020
A metalized plastic capacitor stands a higher chance to clear faults when embodied with thinner electrodes. However, it is not clear whether the same thickness effect applies to carbon-based compliant electrodes in clearing the defects in dielectric ...
