A semi-analytical model for calculating touch-point pressure and pull-in voltage for clamped diaphragms with residual stress

Sharma A., George P.J., University, IN

A closed form model for calculating touchpoint pressure and pull-in voltage is proposed for a clamped square diaphragm under the influence of residual stress. The governing differential equation is solved to get the closed form [...]

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 [...]

Simulation of Cantilever Beam Micro-switch Pull-in and Collapse Voltages

Reid J.R., Starman L.A., Air Force Research Laboratory, US

Simulations of cantilever beam micro-switches such as those shown in Figure 1 exhibit two important operational voltages: the pull-in voltage when contact is initiated at the landing electrode, and the collapse voltage when the cantilever [...]

Simulation of Carbon Nanotube-based Nanoelectromechanical Switches

Dequesnes M., Rotkin S.V., Aluru N.R., University of Illinois at Urbana-Champaign, US

We study the pull-in voltage characteristics of several multiwall nanotube electromechanical switches such as suspended carbon nanotubes over a graphitic ground lectrode. Electromechanical analysis has been performed by accounting for three coupled energy domains: elastostatics, [...]

RF Measurement Techniques for Micro-Cantilever Characterization and Application

Wang C-H, Weber R.J., Iowa State University, US

The reflection coefficient (S11) of a one-port device is most sensitive to its input impedance if a matched condition is obtained. This implies two methods to measure the deflection-induced impedance change for a 1-port device [...]

A Novel Approach for Determining Pull-In Voltages in Micro-electro-mechanical Systems (MEMS)

Long D.S., Shannon M.A., Aluru N.R., University of Illinois at Urbana-Champaign, US

In this paper we introduce a novel method, based on the Lagrange Multiplier Method (LMM), for calculating pull-in voltages in MEMS. This method combines the finite-element with a displacement constraint and boundary element method. The [...]
