Remote control of moving sessile droplets

TL;DR

This paper demonstrates that combined vertical and horizontal vibrations can remotely control the two-dimensional motion of sessile droplets, expanding on previous findings to enable remote manipulation.

Contribution

It introduces a method for remote 2D control of sessile droplets using combined vibrations, generalizing prior work on droplet motion control.

Findings

Remote 2D droplet control demonstrated

Vibrations induce controlled droplet motion

Method applicable for fluid dynamics visualization

Abstract

We recently put in evidence (\cite{noblin2}) that combined vertical and horizontal vibrations can induced a controlled motion of a sessile supported drop. In this video we generalize this finding and demonstrate that a remote 2d controlled motion is possible. This video was submitted as part of the Gallery of Fluid Motion 2010 which is showcase of fluid dynamics videos.
