Abstract

Dielectric elastomer actuators (DEAs), with the advantages of high energy density, large actuation strain and light weight, have been explored for numerous assistive related applications, including refreshable tactile displays, tunable optics, and bio-mimic robotics. However, their steps to practical applications are limited by the poor reliability and durability, especially under large actuation strain. Here we report a self-clearable compliant electrode comprising an ultra-thin singlewalled carbon nanotube (SWNT) electrode with an overcoated thin polymer layer. This bilayer electrode can provide the acrylic-based DEAs with a long lifetime stably under both cyclic and continuous actuation at 150% actuation strain in area.
