Abstract:The microfluidic handling technologies have broad application prospects
   in many fields, such as biology, chemistry, micromechanics and so on.
   Microdroplet, as a form of microfluidics, its movement patterns and
   handling technologies have attracted great concern. In this work, with
   the Cu(CH3(CH2)12COO)2 surface (a superhydrophobic surface with
   two-level rough structure) as substrate, we study the microdroplets
   electrowetting phenomenon under DC electric field. Then, the
   electrowetting induced oscillation of microdroplets is studied by
   applying AC electric field. We discuss and analyze some factors on the
   oscillation properties of droplets, for instance, the impacts of
   electric field frequency, voltage amplitude and the droplet size.
