Negative-Poisson’s-Ratio (NPR) Microstructural Material by Soft-Joint Mechanism

Lu Y-W, Chang C-J, Lin P-T, Gea H-C, Rutgers University, US

We present an example of making a negative-coefficient material - Negative Poisson’s Ratio (NPR) material, which expands in the cross section when stretching. The NPR materials can provide unique characteristics in energy absorption. The NPR [...]

Electromechanical System for Lorentz Force Compensation

Sekalski P., Napieralski A., Simrock S., Technical University of Lodz, PL

The cavity is the main element of each linear accelerator used for high-energy physics purpose. The resonant frequency of cavities depends on its shape. Due to the pulse operation they are deformed by dynamic Lorentz [...]

Ultra High performance In-line Contact MEMS RF Switch

Hong Y-T, Kim C-H, Lee S-H., Kwon S-W, Song I-S, Samsung Advanced Institute of Technology, KR

An in-line direct RF MEMS Switch was presented in this paper. This switch having single contact point was fabricated, and characterized. The switch is a series type and is actuated by a supportive membrane. A [...]

A Capillary Electrophoresis Chip for Rhodamine B and Inorganic Ion detection Utilizing Contactless Capacitance Detection

Liu W.L., Chen W.J., Hsieh S.H., Tsai T.K., National Pingtung University of Science and Technology, TW

A microfluidic channel and a contactless capacitance detector wereintegrated on a glass chip by a semiconductor manufacturing process forseparating and analyzing Rhodamine B and inorganic ion. The electrodes of thecapacitance detector were formed successively by [...]

Dielectrophoretic ratchets for linear and rotary nanomotors

Hughes M.P., Astumian R.D., University of Surrey, UK

Dielectrophoresis (DEP) is a phemomenon of induced particle motion in non-uniform electric fields. In this paper, we will describe how the phenomenon can be used to design electrokinetic ratchet devices to provide both linear and [...]

Investigating the Benefit-Cost of MEMS Application for Structural Health Monitoring of Transportation Infrastructure

Jha M.K., Davy A.B., Morgan State University, US

This paper develops a fuzzy-logic based procedure for quantitative cost and benefit calculation of MEMS application for structural health monitoring of transportation infrastructure. This will be a major step forward for widespread MEMS application in [...]
