Electrostatic stiffness properties of charged bilayers

Physics Letters A, 1989
Abstract We calculate the exact stiffness constants χ, χ: , c0 of mean, Gaussian, and spontaneous curvature for a double layer of surface charges separated by a fixed distance 2d in an electrolyte with finite screening length l0. This extends earlier studies of the limits of very small and very large d/lD.

A sandwich beam with electrostatically tunable bending stiffness

Smart Materials and Structures, 2006
The tuning of the bending stiffness of structural elements is of interest for, among other things, the suppression of vibrations related to resonance phenomena. For a given cross-sectional area and geometry, the variation of the elastic properties of the material composing the structure provides a viable approach to this task. Only very limited options

On the stiffness of an electrostatic suspension in liquid

Technical Physics, 2009
The stiffness of a spherical electrostatic suspension of a sphere in a liquid is calculated for specific shapes of electrodes. The sizes of the electrodes at which the image force does not influence the stability of the suspension are found.

A Micromechanical Mode-Matched Gyroscope Using Stiffness Nonlinearity and Electrostatic Tuning

2021 IEEE 34th International Conference on Micro Electro Mechanical Systems (MEMS), 2021
This work reports design of a dual-mode decoupled single-mass micromechanical gyroscope with a fully symmetrical structure aiming to achieve mode-matching despite of fabrication errors and packaging stress imbalance. Mode-matching is done by combing the spring-hardening effect caused by the nonlinear stiffness of the elastic beam and the linear ...

An electrostatic actuator with variable stiffness for suppression of rebound due to waveform deviations

2017 IEEE SENSORS, 2017
An inherent variable stiffness approach was proposed to suppress the rebound and impact of the electrostatic switch due to waveform deviations. A simple clamped-guided beam spring with large deflection, which generated inherent cubic nonlinear restoring force, was adopted for implementation of the approach.

Electrostatically tunable bending stiffness in a GFRP–CFRP composite beam

Smart Materials and Structures, 2007
The suppression of vibrations in structures is commonly considered a useful measure for the extension of their lifetime, when high amplitude vibrations are observed. In the experiments presented in this work, the modification of the stiffness of a beam as a means to suppress vibrations due to resonance is proposed as an alternative to the introduction ...
