A large-strain and ultrahigh energy density dielectric elastomer for fast moving soft robot

Nature Communications
Dielectric elastomer actuators (DEAs) with large actuation strain and high energy density are highly desirable for actuating soft robots. However, DEAs usually require high driving electric fields (>100 MV m−1) to achieve high performances due to the low

Self-Sensing Control for Soft-Material Actuators Based on Dielectric Elastomers [PDF]

, 2019
Due to their energy density and softness that are comparable to human muscles dielectric elastomer (DE) transducers are well-suited for soft-robotic applications. This kind of transducer combines actuator and sensor functionality within one transducer so

Contact-separation-induced self-recoverable mechanoluminescence of CaF2:Tb3+/PDMS elastomer

Nature Communications
Centrosymmetric-oxide/polydimethylsiloxane elastomers emit ultra-strong non-pre-irradiation mechanoluminescence under stress and are considered one of the most ideal mechanoluminescence materials.

Interdigitation between surface-anchored polymer chains and an elastomer : consequences for adhesion promotion

, 2004
We study the adhesion between a cross-linked elastomer and a flat solid surface where polymer chains have been end-grafted. To understand the adhesive feature of such a system, one has to study both the origin of the grafted layer interdigitation with ...

A scanning force microscopy study on the morphology of elastomer-coagent blends [PDF]

, 1993
Atomic force scanning microscopy (AFM) was used to investigate the dispersion of low molecular weight compounds in ethylene-propylene copolymers (EPM). Where other microscopical techniques failed to provide morphological details of this type of blend, as

Volume changes measurement of elastomers using 3D DIC

Acta Polytechnica CTU Proceedings, 2023
The presented research aims at measuring the volume changes of elastomers using digital image correlation (DIC) in the 3D configuration (stereo DIC). The deformation measurement method in stereo configuration was applied during the mechanical testing of

Dielectric elastomer actuators

Journal of Applied Physics, 2021
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). This Tutorial describes the physical basis underlying the operation

Characterization of soft stripe-domain deformations in Sm-C and Sm-C* liquid-crystal elastomers [PDF]

, 2008
The neoclassical model of Sm-C (and Sm-C*) elastomers developed by Warner and Adams predicts a class of “soft” (zero energy) deformations. We find and describe the full set of stripe domains—laminate structures in which the laminates alternate between ...
