Overview

Microdrops and interfaces are now a common feature in most fluidic microsystems, from biology, to biotechnology, materials science, 3D -microelectronics, optofluidics, and mechatronics. On the other hand, the behaviour of droplets and interfaces in today's microsystems is complicated and involves complex 3D geometrical considerations. From a numerical standpoint, the treatment of interfaces separating different immiscible phases is difficult. This book aims to give the reader the theoretical and numerical tools to understand, explain, calculate and predict the often non intuitive, observed behaviour of droplets in microsystems. After a chapter dedicated to the general theory of wetting, the book successively
• presents the theory of 3D liquid interfaces,
• gives the formulas for volume and surface of sessile and pancake droplets,
• analyses the behaviour of sessile droplets,
• analyses the behaviour of droplets between tapered plates and in wedges,
• presents the behaviour of droplets in microchannels
• investigates the effect of capillarity with the analysis of capillary rise,
• treats the onset of spontaneous capillary flow in open microfluidic systems,
• analyses the interaction between droplets, like engulfment,
• presents the theory and application of electrowetting,
• presents the state of the art for the approach of 3D- microelectronics using capillary alignment.

Meet the Author

Jean Berthier is a Scientist at the CEA/LETI and teaches at the University of Grenoble, France. He is presently involved in the development of microdevices for liquid-liquid extraction (LLE), flow focusing devices (FFD) for bio-encapsulation of live cells, microfluidic resonators for high sensitivity biodetection and numerical methods for the prediction of droplets and interfaces behavior in microsystems. He is the first author of the book Microfluidics for Biotechnology published in 2005 with a second edition in 2010. He is also the author of the book Microdrops and Digital Microfluidics, published in 2008.

Kenneth A. Brakke is Professor of Mathematics and Computer Science at Susquehanna University in Pennsylvania. He received his PhD in mathematics from Princeton University in the field of geometric measure theory. Since 1988, he has written and maintained his freely available Surface Evolver software, which shows computer models of liquid surfaces.
