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 behavior 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.
After a chapter dedicated to the general theory of wetting, this practical book successively details:
- The theory of 3D liquid interfaces
- The formulas for volume and surface of sessile and pancake droplets
- The behavior of sessile droplets
- The behavior of droplets between tapered plates and in wedges
- The behavior of droplets in microchannels
- The effect of capillarity with the analysis of capillary rise
- The onset of spontaneous capillary flow in open microfluidic systems
- The interaction between droplets, like engulfment
The theory and application of electrowetting
- The state of the art for the approach of 3D-microelectronics using capillary alignment
