Description

Electrowetting (EW) is one of the most versatile tools to manipulate drops on the sub-millimeter length scale. It provides active control over the energy landscape experienced by liquids at interfaces for a broad range of applications including drop-based microfluidics, adaptive optics, and display technology. After a brief review of basic physical concepts of electrowetting, I will illustrate the capabilities of electrowetting with examples of switchable superhydrophobic surfaces and enhanced drop sliding on inclined plains that enable a detailed control of drop condensation patterns from supercooled vapor for enhanced heat transfer. Moreover, I will discuss are series of recent experiments on adaptive optofluidic lenses that allow not only for varying the focal length but also for a detailed control of optical aberrations and general wavefront shaping
