Parametric evaluation of device performance as a function of fiber density (2r/d) and dielectric thickness (h/d). (a) 3D surface plot representing the effect of fiber density (2r/d) and dielectric thickness (h/d) on the E-field localization, (b) failure mechanism of the actuators, regions shaded in blue represent failure due to the electrical breakdown (EB), regions shaded in red represent failure due to the electromechanical instability (EMI), (c) contour plot of the actuation strain dependency to the fiber density (2r/d) and fiber spacing (h/d) values, (d) 3D surface plot representing the effect of fiber density (2r/d) and dielectric thickness (h/d) on the DEA actuation strain.
