Phys. Lett. 104 (6) (February 10): 062902. doi:10.1063/1.4865200.0003-6951http://nrs.harvard.edu/urn-3:HUL.InstRepos:13910568Hydrogels containing electrolyte can work as ionic conductors to actuate dielectric elastomer (DE) artificial muscles. Based on a popular design of a circular actuator, we study theoretically and experimentally the cyclic performance of acrylic DE actuators with solid hydrogel electrodes. The viscoelasticity of solid electrodes constrains the maximum strain that is attainable for one cycle of triangular voltage, and it also diminishes the accumulated increment of the maximum strain after many cycles of loadings.en-USJournal Article2015-01-25Yuanyuan Bai, Yanhui Jiang, Baohong Chen, Choon Chiang Foo, Feng Xiang, Jinxiong Zhou , Hong Wang, and Zhigang Suo2015-02-0310.1063/1.4865200
