Finite Element Modeling and Analysis of CMOS-SAW Sensors

Tigli O., Zaghloul M.E., Washington State University Vancouver, US

Finite element (FE) modeling and performance analysis of Surface Acoustic Wave (SAW) devices that are developed in CMOS (Complementary Metal Oxide Semiconductor) technology are presented. CMOS-SAW devices were designed, fabricated and characterized as a biosensor [...]

Improved Modeling of the Comb Drive Levitation Effect

Li F., Clark J.V., Purdue University, US

Lumped comb drive models found in the literature ignore the electrostatic levitation effect, which decreases their accuracy. The levitation effect occurs when the substrate is within close proximity to the comb drive. This common configuration [...]

Passive Temperature-Compensation of MEM Resonators

Rottenberg X., Jansen R., Stoffels S., De Coster J., De Raedt W., De Coster J., De Raedt W., Tilmans H.A.C., IMEC, BE

MEM-resonators are recognized key components for future sensing, wireless and communications applications. Si-based resonators have gained special interest since they offer the perspective to replace bulky quartz resonators on-chip, maintaining high Q-factor and reaching high [...]

Dynamic Compact Thermal Model of an Electrothermal Micromirror Based on Transmission Line Theory

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

The two main challenges in electrothermal MEMS design are their slow response and inherently low efficiency. Therefore, thermal modeling is essential for design and optimization. A compact parametric model is desirable as it computationally efficient [...]

An Online Electrostatics Modeling Tool for Microdevices with Dirichlet Boundary Conditions by Schwarz-Christoffel Mapping

Li F., Clark J.V., Purdue University, US

We present an online software tool that quickly and accurately models and simulates the electrostatic properties, such as capacitance, charge distribution, and electrostatic force, of microdevices in 2.5D domain with Dirichlet boundary conditions by using [...]

Calibration and Validation Procedure for Reliable and Predictive High-level Transducer Models Suited for System-level Design

Khalilyulin R., Schrag G., Wachutka G., Münich University of Technology, DE

We present an elaborated parameter extraction and model validation procedure for high-level transducer models that are aimed for system-level design as well as for hardware-software co-simulation (Matlab/Simulink transducer model embedded in control circuitry) in order [...]

A Sparse Grid based Collocation Method for Model Order Reduction of Finite Element Models of MEMS under Uncertainty

Sumant P.S., Wu H., Cangellaris A.C., Aluru N., University of Illinois at Urbana-Champaign, US

A methodology is proposed for the model order reduction of finite element models of MEMS devices under random input conditions. In this approach, the reduced order system matrices are represented in terms of their convergent [...]

Designing universal oligonucleotides for DNA/nanoparticle conjugates

Ivan G., Grolmusz V., Eotvos Lorand University, HU

As DNA sequences originating from different species are highly specific, it is a challenge to design “universal” DNA/nanoparticle conjugates that are able to hybridize to each member of a set of nucleotide sequences. Possible applications [...]

Novel first-principle simulations of 3D atomistic structure

Zhang D., Polizzi E., UMass, US

Modeling approaches in computational electronics have become increasingly driven by the need of more fundamental and comprehensive understanding of the nanoscale physics of system only through knowledge of the constituent atoms. First principle calculation, which [...]

MD boundary conditions for pressure gradient flows: nano-mixing, and nano-droplet deformation in extensional flows

Borg M.K., Nicholls W., Reese J.M., University of Strathclyde, UK

We develop new non-periodic boundary conditions in molecular dynamics (MD) simulations, applied to inlets and outlets of nanochannel flow problems. We demonstrate Poiseuille-type flow simulations for two applications in relatively complex geometries: a mixing channel [...]
