Fabrication and actuation characterisation of a new UV curing acrylic dielectric elastomer
IET Nanodielectrics, 2022 Most commonly used dielectric elastomers (DEs) such as acrylic dielectric elastomers VHBTM 4910 need a high actuation voltage and pre‐stretching to obtain a large actuation strain, and present high mechanical loss caused by viscoelasticity. In this work,

Wireless Powered Dielectric Elastomer Actuator [PDF]
IEEE Robotics and Automation Letters, 2021 The need for cable connection with soft robotic systems suppresses the benefits granted by their softness and flexibility. Such systems can be untethered by equipping batteries or by relying on non-electrical actuation mechanisms. However, these approaches cannot simultaneously support long-term and intelligent operations.
