Book Description
After spending over 12 years developing new microsystems for biotechnology – especially concerned with the microfluidic aspects of these devices – Jean Berthier is considered a leading authority in the field. Now, following the success of his book, Microfluidics for Biotechnology, Dr. Berthier returns to explain how new miniaturization techniques have dramatically expanded the area of microfluidic applications and microsystems into microdrops and digital microfluidics. Engineers interested in designing more versatile microsystems and students who seek to learn the fundamentals of microfluidics will all appreciate the wide-range of information found within Microdrops and Digital Microfluidics.

Book Description
This book provides an insightful guide to the design, testing and optimization of micro-electrode-dot-array (MEDA) digital microfluidic biochips. The authors focus on the characteristics specific for MEDA biochips, e.g., real-time sensing and advanced microfluidic operations like lamination mixing and droplet shape morphing. Readers will be enabled to enhance the automated design and use of MEDA and to develop a set of solutions to facilitate the full exploitation of design complexities that are possible with standard CMOS fabrication techniques. The book provides the first set of design automation and test techniques for MEDA biochips. The methods described in this book have been validated using fabricated MEDA biochips in the laboratory. Readers will benefit from an in-depth look at the MEDA platform and how to combine microfluidics with software, e.g., applying biomolecular protocols to software-controlled and cyberphysical microfluidic biochips.

Book Description
Microfluidic devices that do not require bulky peripheral hardware, such as pumps and external battery/power supplies, are a suitable technology for portable applications in resource-constrained settings, such as point-of-care (POC) diagnosis in developed countries, environmental monitoring, and on-site forensic analysis, etc. The existing portable microfluidic devices are mostly based on microchannel structures, in which the pre-defined channels limit their functional flexibility, rendering them difficult to scale up. Digital microfluidics, on the other hand, can tackle this problem since they deal with discrete droplets individually and can therefore provide more on-demand flexibility and versatility. Most digital microfluidic devices, however, require external electric power sources. We first propose finger-powered digital microfluidic (F-DMF) based on electrowetting on dielectric (EWOD). Instead of requiring an external power supply, our F-DMF uses piezoelectric elements to convert the mechanical energy produced by human fingers into electric voltage pulses for droplet manipulation. The voltage outputs of piezoelectric element mounted in cantilever beam configuration are studied theoretically and experimentally. Using this energy conversion scheme, the basic modes of droplet operations, such as droplet transport, splitting, and merging on EWOD devices are confirmed. The key assay steps involved in glucose detection and immunoassay are also successfully performed using F-DMF-EWOD. Exploiting the same energy conversion scheme, F-DMF based on the electrophoretic transport of discrete droplets (EPD), which has the potential to overcome pinning and surface contamination often encountered in EWOD, is then presented. Successful EPD actuation, however, requires the piezoelectric elements to provide both sufficient charge and voltage pulse duration. These requirements are quantified using numerical models to predict the electrical charges induced on the droplets and the subsequent electrophoretic forces. The transport and merging of aqueous droplets as well as direct manipulation of body fluids is experimentally demonstrated using F-EPD-DMF. Further, a mechanical system and an efficient pin-assignment scheme are explored to facilitate the practical implementation of pre-programmed and functional actuation of droplets in the EPD-based system. For the second part of this thesis, one practical issue in digital microfluidics biochip (DMFB) design is discussed: the droplet routing problem, which largely decides the performance and correctness of the system. The problem is formulated to a multi-agent path finding problem (MAPF) and an approximate algorithm based on Independent Detection (ID) is applied to solve the problem. The modified ID algorithm shows promising performance on selected benchmark problems with medium number of droplets ( 12). Overall, it achieves better timing result (~15% reduction) and total routing length (~50% reduction) with no compromise in fault tolerance (indicated by the total number of used cells), when compared with the previous best known results.

Book Description
The Physics of Microdroplets gives the reader the theoretical and numerical tools to understand, explain, calculate, and predict the often nonintuitive observed behavior of droplets in microsystems. 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
