Rev. 2016;68(2):020802-020802-41. doi:10.1115/1.4033570 Figure Legend: Various diagrams of produced actuator thrust as function of (a) operating parameters, (b) dielectric materials, and (c) geometry parameters. Note that the thrust data in Fig. 20(c) are already normalized with the electric power. This ratio will be introduced as fluid mechanic effectiveness in Sec. 3.3.5.
