Abstract

This paper discusses electro-manipulation of droplets for microfluidic applications. There is a growing technology-driven interest in using external influences to move or shape small quantities of liquids, referred to as microfluidic actuation. The use of electrical, rather than mechanical, forces to achieve this actuation is convenient because the resultant devices contain no moving parts. Existing non-mechanical microfluidic actuation techniques that are driven by the application of a voltage include electrowetting and liquid dielectrophoresis, with many applications including lab-on-a-chip, polymer surface patterning, as well as optimisation of optical properties for polymer microlenses, and droplet driven displays.
