dc.description.abstract | Electroactuation of liquid-liquid interfaces
offers promising methods to actively modulate droplet
formation in droplet-based microfluidic systems. Here,
flow-focusing junctions are coupled to electrodes to control
droplet production in the well-known jetting regime.
In this regime, a convective instability develops
leading to droplet formation at the end of a thin and
uniform, long liquid finger. We show that in AC electric
fields the jet length is a function of both the magnitude
of the applied voltage and the electrical parameters
such as the frequency of the AC field and the
conductivity of the dispersed phase.We explain that dependency
using a simple transmission line model along the liquid jet. An optimum frequency to maximize the
liquid ligament length is experimentally observed. Such
length simply cannot be obtained by other means under
the same operating conditions, in the absence of the
AC signal. At low frequency, we reach a transition from
a well-behaved, uniform jet brought about near the optimum
frequency to highly unstable liquid structures in
which axisymmetry is lost rather abruptly | es |
