Dielectric elastomer actuators under equal-biaxial forces, uniaxial forces, and uniaxial constraint of stiff fibers
Lu, Tongqing; Huang, Jiangshui; Jordi, Christa; Kovacs, Gabor; Huang, Rui; Clarke, David R.; Suo, Zhigang (Royal Society of Chemistry, 2012)A membrane of a dielectric elastomer deforms when a voltage is applied through its thickness. The achievable voltage-induced deformation is strongly affected by how mechanical loads are applied. Large voltage-induced ... -
Highly deformable actuators made of dielectric elastomers clamped by rigid rings
Lu, Tongqing; Chiang Foo, Choon; Huang, Jiangshui; Zhu, Jian; Suo, Zhigang (AIP Publishing, 2014)In the nascent field of soft machines, soft materials are used to create devices that actuate robots, sense environment, monitor health, and harvest energy. The soft materials undergo large deformation in response to ... -
Large, Uni-directional Actuation in Dielectric Elastomers Achieved By Fiber Stiffening
Huang, Jiangshui; Zhu, Jian; Clarke, David R.; Suo, Zhigang (American Institute of Physics, 2012)Cylindrical actuators are made with dielectric elastomer sheets stiffened with fibers in the hoop direction. When a voltage is applied through the thickness of the sheets, large actuation strains are achievable in the axial ... -
Maximizing the Energy Density of Dielectric Elastomer Generators Using Equi-Biaxial Loading
Huang, Jiangshui; Shian, Samuel; Suo, Zhigang; Clarke, David R. (Wiley-VCH Verlag Berlin, 2013-03-29)Dielectric elastomer generators (DEGs) for harvesting electrical energy from mechanical work have been demonstrated but the energy densities achieved are still small compared with theoretical predictions. We show that ... -
Pattern formation in plastic liquid films on elastomers by ratcheting
Huang, Jiangshui; Yang, Jiawei; Jin, Lihua; Clarke, David R.; Suo, Zhigang (Royal Society of Chemistry (RSC), 2016)Plastic liquids, also known as Bingham liquids, retain their shape when loads are small, but flow when loads exceed a threshold. We discovered that plastic liquid films coated on elastomers develop wavy patterns under ... -
Spontaneous and Deterministic Three-Dimensional Curling of Pre-Strained Elastomeric Bi-Strips
Huang, Jiangshui; Liu, Jia; Kroll, Benedikt; Bertoldi, Katia; Clarke, David R. (Royal Society of Chemistry, 2012)Three dimensional curls (“hemi-helices”) consisting of multiple, periodic and alternating helical sections of opposite chiralities, separated by perversions, are one of a variety of complex shapes that can be produced by ... -
The Thickness and Stretch Dependence of the Electrical Breakdown Strength of an Acrylic Dielectric Elastomer
Huang, Jiangshui; Shian, Samuel; Diebold, Roger Mitchell; Suo, Zhigang; Clarke, David R. (American Institute of Physics, 2012)The performance of dielectric elastomer actuators is limited by electrical breakdown. Attempts to measure this are confounded by the voltage-induced thinning of the elastomer. A test configuration is introduced that avoids ...
