Dr. Jean Berthier Senior scientist at CEA-Leti, Grenoble, France About the author Jean Berthier is a Scientist at the CEA/LETI and teaches at the University of Grenoble. He received an Engineering Diploma from the Institut National Polytechnique, and a MS in Mathematics from the University of Grenoble and a PhD from the University UPMC-Sorbonne in Paris. He is presently involved in the development of microdevices for liquid-liquid extraction (LLE), flow focusing devices (FFD) for bio-encapsulation of live cells, suspended microfluidic resonators (SMR) for high sensitivity biodetection, capillary self-alignment (CSA) for 3D microelectronics, and numerical methods for the prediction of droplets and interfaces behavior in microsystems. He is the first author of the book Microfluidics for Biotechnology first published by Artech House in November 2005, with a second edition in 2010. He is also the author of the book Microdrops and Digital Microfluidics published by William Andrew/Elsevier in February 2008 with a second edition due in December 2012. He is the first author of the book “The Physics of Microdroplets” published in 2012 by Scrivener/Wiley Publishing. He is a member of the editorial board of the journals Biomicrofluidics and Modern Instrumentation, a member of the American Chemical Society, and of the French Observatory for Micro and Nano Technology (OMNT). He has published numerous scientific papers and patents. |

Abstract
Microfluidic systems have found many applications: They are used in Biotechnology, Biology, Microelectronics, Mechatronics, Optofluidics, etc. An interesting subdomain of microfluidics is capillarity. The first reason of the growing popularity of the use of capillary forces in microsystems is the absence of external pumping systems, or on-chip moving parts. Capillary systems are passive and usually costless. The second reason is that, at the microscale, capillary forces are overcoming most of usual forces, like weight and inertia. In the presentation, I will focus on the main aspects of capillarity with the basic laws and their applications. I have selected three main groups of applications: digital microfluidics based on electrowetting, open microfluidics based on spontaneous capillary flows, capillary self-alignment with its applications to 3D microelectronics.
