A journal paper entitled “Physics-based Modeling of Mechano-electric Transduction of Tube-shaped Ionic Polymer Metal Composite,” was recently published in Journal of Applied Physics (Vol. 117, 114903, 2015; http://dx.doi.org/10.1063/1.4914034). This paper reports our research results in a physics-based model that is proposed to simulate mechanoelectrical transduction of 3D shaped ionic polymer metal composites. The lead author Tyler Stalbaum is a PhD student in the Mechanical Engineering Department of UNLV.

A journal paper entitled “Ionic Electroactive Polymer Artificial Muscles in Space Applications,” was recently published in Scientific Reports (Vol. 4, 6913, 2014; http://www.nature.com/ srep/2014/141105/srep06913/fig_tab/ srep06913_T1.html). This paper includes our research results regarding the material behaviour of ionic polymer-metal composite actuator under prolonged exposure to space environment. This paper was based upon a multi-national collaborative effort including European Space Agency and NASA EPSCoR.
