Microelectrofluidic Systems: Modeling and Simulation by Tianhao Zhang

By Tianhao Zhang

Composite structures that combine microelectromechanical and microelectrofluidic (MEF) parts with electronics are rising because the subsequent iteration of system-on-a-chip (SOC) designs. despite the fact that, there is still a urgent want for a dependent method for MEFS layout automation, together with modeling innovations and simulation and optimization tools.Integrating top-down and bottom-up layout philosophies, Microelectrofluidic structures provides the 1st finished layout approach for MEFS. This technique helps hierarchical modeling and simulation from the part point to the method point. It results in multi-objective optimization instruments helpful in all levels of the layout strategy, from conceptualization to ultimate production. The authors commence through defining the fundamental variables and parts had to describe MEFS habit, then version that habit throughout 3 layers of abstraction: the low-level part, high-level reconfigurable structure, and bio/chemical program layers. they've got built a hierarchical built-in layout setting with SystemC and current its structure and linked sensible packages.Microelectrofluidic platforms is visionary in its leverage of digital layout ideas for microsystem layout and heralds a brand new period of computerized SOC layout. the method it provides holds the possibility of major rate reductions in layout time and life-cycle upkeep expenses, and its ideas and instruments for strong layout and alertness flexibility can result in the high-volume construction wanted for the unavoidably becoming product marketplace.

3 Two-port transducer consists of two energy domains. An ideal energy transduction process is lossless, and power is transmitted with no energy storage or dissipation associated with the transduction process. 19) Additionally, the relationship between the across variable and the through variable are represented by constant coefficients and are linear. 20) where ½½ , ½¾ , ¾½ , and ¾¾ are constants that depend on the particular transducer. 20) yields two possible ideal two-port transducers: 27 HIERARCHICAL MODELING ¯ ¯ Transforming Transducer ½¾ ¾½ ¼ Ò ¾¾ ½ ½½ ¾¾ ¼ Ò ¾½ ½ ½½ Gyrating Transducer ½¾ These two general solutions are the only nontrivial solutions for the ideal two-port transduction.

In addition, the essential solid body characteristics allow micromechanical systems to be analyzed as lumped-element models [34]. The variables at a given spatial location in a solid body can always be used to represent the variables of other regions. In order to account for the elasticity and tortures of deformation, the solid body has to be cut into several lumps. Then, by applying a pertinent physical law to the solid body, a set of simultaneous ODAEs are generated. The solution of these equations describe the system dynamic behavior.

A uniform classification of variables associated with power and energy is necessary to conveniently model the system’s coupled-energy domain behavior. MEFS modeling and simulation methodologies are always based on analogies between these variables in different energy domains. The principle of energy-conservation provides the basic methodology to characterize and define the fundamental variables in mechanical, electrical, fluid, and thermal energy domains [34]. The physical quantities in multiple energy domains can be viewed as types of singleport element variables: across and through.
