Beyond Planar: Enhanced Performance of Hollow Fiber Dielectric Elastomer Actuators.

ABSTRACT: Hollow fiber dielectric elastomer actuators (HFDEAs) offer several advantages over their conventional counterpart, planar dielectric elastomer actuators (DEAs). Due to their simple shape, flexibility, and conformability, HFDEAs are promising candidates for complex applications within soft robotics. This paper offers a comprehensive comparison between the actuation behavior of planar and HFDEAs using both analytical and numerical models. An electro-mechanical model establishes analytical correlations between the applied voltage and resulting strain. The results from the simplified model are subsequently compared with a numerical model in COMSOL Multiphysics, where simulations are run in more realistic conditions. Supporting experiments are conducted on HFDEAs with different geometries to va
