Analysis and Simulation of Curved Bimorph Microactuators

Pal S., Xie H., University of Florida, US

Difference in strains in the two layers of a bimorph causes it to curl, thereby leading to actuation. Thermal, piezoelectric and shape-memory alloy based straight bimorph actuators have been widely reported. However, little attention has [...]

Design and Fabrication of a Low Power Electro-thermal V-shape Actuator With Large Displacement

Khazaai J., Oakland University, US

We propose the design and microfabrication of a V-shape MEMS electro-thermal actuator featuring large displacement generation and low power consumption. Electro-thermal MEMS actuators are suitable for a variety of applications where large forces and long [...]

Design Simulations of MEMS Micropump by 3D Fluid-Structure Interaction Analysis

Johari J., Universiti Kebangsaan Malaysia, MY

The major technical impediment in developing new microdevices lies in the lack of understanding physical phenomena and their interactions of thermal, mechanical, electric, magnetic and/or fluidic fields for performing their intended functions. Due to the [...]

A visual approach on MEMS process modeling using device cross-sections

Schmidt T., Mielke M., Hahn K., Ortloff D., Popp J., Brueck R., University of Siegen, DE

With MEMS entering fast moving consumer markets the need for more efficient design concepts becomes apparent. A technology centered approach where a product is designed around a highly specialized and optimized technology cannot cope with [...]

Development of Device-Level Chemical-Mechanical Polishing Simulation Module Using Cellular Automata Method

Yeh H.-M., Chen K.-S., National Cheng Kung University, TW

This work briefly presents the basic theory, the development, and a primary demonstration of a device-level chemical-Mechanical Polishing (CMP) CAD module. By integrating the phenomenological material removing relation such as Preston’s equation, contact mechanics, finite [...]

3D Molecular Theory of Solvation for Nanochemistry in Solution

Kovalenko A., National Institute for Nanotechnology, CA

Predictive molecular modeling of nanosystems in solution, important in many applications, requires long-time description of millions molecules, which is by far not feasible with ab initio methods, challenging for molecular simulations, and problematic for continuum [...]

Designing nanomaterials mechanical properties from the observable nanostructure features

Tengen T.B., Vaal University of Technology, ZA

Recent findings report that both mean grain size and dispersion should be used to design nanomaterials with desired mechanical properties. Grain size deals with “equivalent radius” that assumes that grains are spherical. But two grains [...]

Application of Computational Chemistry to Nanotechnological Problems

Gusarov S., Kovalenko A., National Institute for Nanotechnology, CA

Computer modeling and simulation are crucial in understanding and controlling structure-property relations by explaining experimental data and by revealing critical conceptual issues about the underlying mechanisms whose resolution requires excessive experimentation. There is a great [...]

Simulation of Self-Assemblig Monolayers of Complicated Organic Molecules at the Interface

Fefelov V.F., Gorbunov V.A., Myshlyavtsev A.V., Myshlyavtseva M.D., Myshlyavtseva M.D., Omsk State Technical University, RU

In present paper we construct and study the simple model of self-assembled monolayer (SAM) with several different orientations of complicated organic molecules with respect to interface. In order to study the model we used transfer-matrix [...]

The Simplest Model of Multisite Adsorption of Molecules with Different Orientation in Adlayer

Fefelov V.F., Gorbunov V.A., Myshlyavtsev A.V., Myshlyavtseva M.D., Myshlyavtseva M.D., Omsk State Technical University, RU

The aim of the work is construction and study of the simplest model of multisite adsorption of molecules with different orientation in adlayer. To construct the model lattice gas (LG) model is used. In the [...]
