In this paper, a theoretical approach is devised to analyze the droplet dynamics in a
microchannel subjected to electrocapillary actuation mechanisms. Specific attention is
devoted to estimate the influences of the applied potentials and the hydrophobic insulation
thicknesses, so as to obtain suitable interelectrode spacings, for a given droplet size. It is
revealed that there exists a threshold limit on the value of the interelectrode pitch, beyond
which the overall microfluidic transport rates are substantially lowered. On the other hand …
