FIG. 1.

The non-saturation response of a 4-mm dielectric liquid droplet at different applied voltages. (a) The experimental side-view images of the liquid droplet were captured with applied voltages of (1) 21 V, (2) 113 V, and (3) 215 Vrms, which corresponds to contact angles of 22°, 90°, and 176°, respectively. (b) Experimental data and curve fitting using Eq. (1) are plotted in black dots and in red line, respectively.

Image of FIG. 2.
FIG. 2.

Cross section of energy distributions of a dielectric droplet with 4 mm in diameter under an applied voltage of 215 Vrms.

Image of FIG. 3.
FIG. 3.

The information of a dielectric droplet in liquid actuated at 113 Vrms and 215 Vrms, respectively. (a) The profiles of a droplet, (b) the magnitude of dielectric force acting on the liquid-liquid interface, and (c) the strength of electric fields on the solid-liquid interface.
