Modeling and Design of Electrostatic Voltage Sensors Based on Micromachined Torsional Actuators

Dittmer A., Dittmer J., Dittmer A., Dittmer J., Judaschke R., Büttgenbach S., Technische Universität Braunschweig, DE

The optimization of design parameters and methods for electrostatic voltage sensors based on torsional actuators is presented. The analytical software model used for this optimization process is discussed and compared to measurement results. Voltage excitation [...]

Stacked Coupled-Disk MEMS Resonators for RF Applications

Nygaard K.H., Grinde C., Fjeldly T.A., Norwegian University of Science and Technology, NO

A novel, stacked coupled-disk resonator design is presented where the silicon discs vibrate in radial contour modes, actuated by electrodes wrapped around the disk periphery. The self-aligned, central stem mediates the coupling and also anchors [...]

Systematic Approach on Modeling and Identification for Nanobattery Prototyping

Bhattacharya P., Ye Z., Walker E., Lacy F., Banerjee M., Southern University, US

Nanobattary microstructure consists of anode, cathode, electrolyte, separator for miniaturized power source. Miniaturization is a challenging area of research. Miniature power sources have a variety of applications on miniature power-controlled devices. Li-Ion is selected by [...]

Modeling the electrical characteristics of FET-type sensors for biomedical applications

Deen M.J., Shinwari M.W., McMaster University, CA

Uniquely examining and identifying biological pathogens is of great importance in health care, as it facilitates early detection, isolation and possibly prevention of many diseases. Availability of highly efficient and easily produced sensors could have [...]

Frequency Domain Modeling of SAW Devices

Wilson W.C., Atkinson G.M., NASA Langley Research Center, US

The lack of integrated design tools for MEMS devices in general, and for Surface Acoustic Wave (SAW) devices specifically, has led to the development of tools that will enable integrated design, modeling, simulation, analysis and [...]

Conditional Probabilistic Modeling of Carbohydrate Metabolism

Barjis I., Sierra M., New York City College of Technology, US

The ongoing processes of metabolic network are very complex, and consequently, difficult to understand and teach; furthermore, it is impossible to predict and analyze it when unpredictable changes are made. Because of the complexity of [...]

A Kinetic Study of the MOCVD of GaN

Moscatelli D., Cavallotti C., Politecnico di Milano, IT

Quantum chemistry investigations have been performed to study the gas phase chemistry active during the MOVPE of GaN when Ga(CH3)3 and NH3, diluted in a H2 carrier gas, are used as precursors. Optimized molecular geometries, [...]

Monte Carlo Algorithm for Nanoscale Electro-Thermal Optimization

Skorek A.W., Ble S.V., Anders G., Nazarko J., University of Quebec at Trois-Rivieres, CA

In this paper, we will present a Monte Carlo method based algorithm established for a sample nanoelectronics device. We are assuming that at the nanoscale level like at the highest the thermal phenomena are important [...]

Continuum Modeling the Behavior of Carbon Nanotubes in different load condition

Chaboki A., Sadrnejad S.A., Yahyaiee M., University of Sydney, AU

Molecular dynamics and quantum mechanics are the best method for analysis the CNTs behavior. Bur because of the difficulties and cost, this task is limited to small structure with limited atoms number. In this paper, [...]

Fabrication and Modeling of CNT Field-Emission Devices

Koohsorkhi J., Rouhi N., Abdi Y., Mohajerzadeh S., Robertson M.D., Thompson R.D., Acadia University, CA

We report the fabrication of field-emission devices based on vertically aligned carbon nanotubes that possess a novel gate structure with applications in flat-panel displays, nanolithography systems and new sensor technologies. The devices consist of CNTs [...]
