Modeling of a Dielectric Elastomer Bender Actuator
Actuators, 2014 The current smallest self-contained modular robot uses a shape memory alloy, which is inherently inefficient, slow and difficult to control. We present the design, fabrication and demonstration of a module based on dielectric elastomer actuation.

Phase chirality and stereo-selective swelling of cholesteric elastomers [PDF]
, 2003 Cholesteric elastomers possess a macroscopic ``phase chirality'' as the director n rotates in a helical fashion along an optical axis $z$ and can be described by a chiral order parameter.
