    • Charge localization instability in a highly deformable dielectric elastomer 

      Lu, Tongqing; Keplinger, Christoph; Arnold, Nikita; Bauer, Siegfried; Suo, Zhigang (AIP Publishing, 2014)
      This paper shows that a highly deformable capacitor made of a soft dielectric and two conformal electrodes can switch between two states discontinuously, by a first-order transition, as the total charge varies gradually. ...
    • 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 ...
    • Electromechanical Catastrophe 

      Lu, Tongqing; Cheng, Sibo; Li, Tiefeng; Wang, Tiejun; Suo, Zhigang (World Scientific Pub Co Pte Lt, 2016)
      A transducer is a system that couples two loads. For example, an electromechanical transducer couples a mechanical force and an electrical voltage. A two-load, nonlinear system can exhibit rich behavior of bifurcation, ...
    • 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 ...
