Fractal Pull-in Stability Theory for Microelectromechanical Systems

open access: yesFrontiers in Physics, 2021
Pull-in instability was an important phenomenon in microelectromechanical systems (MEMS). In the past, MEMS were usually assumed to work in an ideal environment.

Numerical and Analytical Study on the Pull-in Instability of Micro-Structure under Electrostatic Loading [PDF]

open access: yes, 2006
The one-mode analysis method on the pull-in instability of micro-structure under electrostatic loading is presented. Taylor series are used to expand the electrostatic loading term in the one-mode analysis method, which makes analytical solution ...

Closed-Loop Control of Electro-Ribbon Actuators

open access: yesFrontiers in Robotics and AI, 2020
Electro-ribbon actuators are lightweight, flexible, high-performance actuators for next generation soft robotics. When electrically charged, electrostatic forces cause the electrode ribbons to progressively zip together through a process called ...

Pull-in and wrinkling instabilities of electroactive dielectric actuators [PDF]

open access: yesJournal of Physics D: Applied Physics, 2010
We propose a model to analyse the insurgence of pull-in and wrinkling failures in electroactive thin films. We take into consideration both cases of voltage and charge control, the role of pre-stretch and the size of activated regions, which are all crucial factors in technological applications of electroactive polymers (EAPs).

Surface instabilities generated by a slider pulled across a granular bed

open access: yesPhysical Review E, 2023
We report an instability of a slider slowly dragged at the surface of a granular bed in a quasistatic regime. The boat-shaped slider sits on the granular medium under its own weight and is free to translate vertically and to rotate around the pitch axis while a constant horizontal speed is imposed.

Static and Dynamic Analysis of Electrostatically Actuated MEMS Shallow Arches for Various Air-Gap Configurations

open access: yesMicromachines, 2021
In this research, we investigate the structural behavior, including the snap-through and pull-in instabilities, of in-plane microelectromechanical COSINE-shaped and electrically actuated clamped-clamped micro-beams resonators.

Snap-through and pull-in instabilities of an arch-shaped beam under an electrostatic loading [PDF]

open access: yes, 2007
The snap-through and pull-in instabilities of the micromachined arch-shaped beams under an electrostatic loading are studied both theoretically and experimentally. The pull-in instability that results in a system collision with an electrode substrate may
