Dielectric Elastomer Actuators with Carbon Nanotube Electrodes Painted with a Soft Brush

open access: yesActuators, 2018
We propose a simple methodology to paint carbon nanotube (CNT) powder with a soft brush onto an elastomer. A large deformation of dielectric elastomer actuator (DEA) occurs according to the small constraint of the electrodes. Uniform painting with a soft

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

open access: yesActuators, 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 ...
