The poster titled ‘Droplet trapping & control on a single Electrowetting-on-dielectric surface’ by Dieter ‘t Mannetje et al. was selected as the second prize winner at the ‘International meeting on Electrowetting’ in Athens, Greece. The poster describes a method to trap and steer droplets of aqueous solutions using Electrowetting, and to filter them based on various properties such as viscosity and droplet size. Moreover, the model used to describe the system can be used for a wide variety of situations, including drops sliding down inclined planes as seen for rain on windows, drops blown off a surface by air flow as can be seen for airplanes, and drops in a two-phase flow driven by the surrounding medium as encountered in microfluidic applications.
