A non-obtrusive technique to characterize dielectric charging in RF-MEMS capacitive switches [PDF]

open access: yes, 2012
Degradation and failure due to dielectric charging has been a dominant and pervasive reliability concern for RF-MEMS switches. Traditionally, the operational lifetime dictated by this degradation phenomenon is extrapolated from a series of measurements ...

Flip-chip distributed MEMS transmission lines (DMTLs) for biosensing applications [PDF]

open access: yes, 2008
Design and characterization of a flip-chip distributed MEMS transmission line (DMTL) are presented. The concept of using this DMTL as a biosensor is then introduced. Radio frequency experiments on the DMTL loaded with biosamples have been conducted using

Pulsed Digital Oscillators for Electrostatic MEMS [PDF]

open access: yes, 2012
This paper introduces a new actuation scheme for implementing Pulsed Digital Oscillators (PDOs) for electrostatic MEMS resonators. In this scheme, the capacitance of the device is biased with a voltage and it is periodically sampled. Short pulses of zero

Friction Reduction for a Rotational Gyroscope with Mechanical Support by Fabrication of a Biomimetic Superhydrophobic Surface on a Ball-Disk Shaped Rotor and the Application of a Water Film Bearing

open access: yesMicromachines, 2017
Friction between contacting surfaces of metal materials restricts the application of mechanical support in the high-precision inertial device of a rotational gyroscope. Instead, a disk- or ring-shaped rotor is electrostatically or magnetically suspended.

Accelerated testing of multi-walled CNT composite electrical contacts for MEMS switches

open access: yes, 2014
The use of gold-coated multi-walled carbon nanotube (Au/MWCNT) bilayer composite surfaces has been discussed in previous work as a method for improving the reliability of switch contacts [1, 2].
