A fractal micro-electromechanical system and its pull-in stability
Journal of Low Frequency Noise, Vibration and Active Control, 2021 Pull-in instability occurs in a micro-electromechanical system, and it greatly hinders its normal operation. A fractal modification is suggested to make the system stable in all operation period. A fractal model is established using a fractal derivative,

Periodic solutions and the avoidance of pull‐in instability in nonautonomous microelectromechanical systems [PDF]
Mathematical Methods in the Applied Sciences, 2021 We study periodic solutions of a one‐degree of freedom microelectromechanical system (MEMS) with a parallel‐plate capacitor under T‐periodic electrostatic forcing. We obtain analytical results concerning the existence of T‐periodic solutions of the problem in the case of arbitrary nonlinear restoring force, as well as when the moving plate is attached ...

Observation of Pull-In Instability in Graphene Membranes under Interfacial Forces [PDF]
Nano Letters, 2013 We present a unique experimental configuration that allows us to determine the interfacial forces on nearly parallel plates made from the thinnest possible mechanical structures, single and few layer graphene membranes. Our approach consists of using a pressure difference across a graphene membrane to bring the membrane to within ~ 10-20 nm above a ...
