Modeling the effect of the increase in the actuation voltage

Jamshidzade M., Cassles J., University of Barcelona, ES

In the past few years many reports have demonstrated the development of RF-MEMS switches considering the mechanical, electrical and chemical behaviors separately. However there are a few works which address the whole aspects of RF-MEMS [...]

Modeling the effect of the increase in the actuation voltage on the dynamic behavior of a RF MEMS switch

Jamshidzadeh M., Casals J., Assistant Professor, IR

Abstract—In the past few years many reports have demonstrated the development of RF-MEMS switches considering the mechanical, electrical and chemical behaviors separately. However there are a few works which address the whole aspects of RF-MEMS [...]

Investigation on capillary force of nanoscale water cluster using a Hybrid AFM-MEMS System

Kwon S., Kim B., Jhe W., Seoul National University, KR

The interaction force between surfaces has a major effect on the behavior of the materials, such as nanoparticles, proteins, various bio-molecules, and so on. The phenomenon of stiction influenced by interaction forces impacts the repetitive [...]

Effect of local curvature on the interaction between hydrophobic surfaces

Hansson P., Swerin A., Thormann E., Claesson P.M., Schoelkopf J., Gane P.A.C., YKI, Institute for surface chemistry, SE

Previous measurements of the attractive interaction between hydrophobic macroscopic surfaces have showed that long-range forces that are considerably stronger than the van der Waals force dominate the interaction Silica nanoparticles have been deposited on substrates [...]

Molecular Simulation of the Nanoscale Water Confined between an Atomic Force Microscope Tip and a Surface

Choi H.J., Kim J-Y, Hong S.D., Ha M.Y., Jang J., Pusan National University, KR

Under ambient humidity, water condenses as a meniscus between an atomic force microscope (AFM) tip and a surface, giving rise to a strong capillary force on the tip. We performed a molecular dynamics simulation of [...]

Manipulation of Capillary force by Electrowetting for Micromanipulation

Chandra S., Batur C., University of Akron, US

Microassembly is the future of MEMS and NEMS technology. But greatest barrier to the idea of micro scale assembly is micromanipulation. The steps in micromanipulation are pickup, moving and releasing and the most difficult part [...]
