The influence of dispersion forces on the dynamic pull-in behavior of vibrating nano-cantilever based NEMS including fringing field effect

Electromechanical instability of nanobridge in ionic liquid electrolyte media: influence of electrical double layer, dispersion forces and size effect

“…The dispersion forces between interacting bodies are generally explained as Casimir or van der Waals (vdW) attractions depending on the distance between the bodies. The effect of dispersion forces on the pull-in instability of nanoactuators operating in non-liquid environments (i.e., gas or vacuum) has been studied by previous researchers [22][23][24][25][26][27][28][29][30]. Herein, we examine the impact of dispersion forces on the pull-in instability of liquid-immersed nanobridge considering the corrections due to the presence of liquid media in between the electrodes.…”

Non-linear dynamic instability of a double-sided nano-bridge considering centrifugal force and rarefied gas flow

“…The instability analysis of nano-structures on the basis of strain gradient theory cen be found in the literature [31][32][33][34]. In the present study, the nonlinear dynamic pull-in instability of a double-sided nano-bridge as an angular speed sensor is investigated.…”

Studying the effects of small scale and Casimir force on the non-linear pull-in instability and vibrations of FGM microswitches under electrostatic actuation

“…Sedighi and his co-workers [55] took the influences of Casimir and van der Waals attractions into account for the analysis of dynamic pull-in instability of vibrating nano-actuators. The Casimir force effect was also considered in the analysis of electrostatically actuated nanoelectromechanical systems (NEMS) [56].…”
