Regularized Model of Post-Touchdown Configurations in Electrostatic MEMS: Interface Dynamics
نویسندگان
چکیده
Interface dynamics of post contact states in regularized models of electrostatic-elastic interactions are analyzed. A canonical setting for our investigations is the field of MicroElectromechanical Systems (MEMS) in which flexible elastic structures may come into physical contact due to applied Coulomb forces. We study the dynamic features of a recently derived regularized model (A.E. Lindsay et al, Regularized Model of Post-Touchdown Configurations in Electrostatic MEMS: Equilibrium Analysis, Physica D, 2014), which describes the system past the quenching singularity associated with touchdown, that is after the components of the device have come together. We build on our previous investigations of steadystate solutions by describing how the system relaxes towards these equilibria. This is accomplished by deriving a reduced dynamical system that governs the evolution of the contact set, thereby providing a detailed description of the intermediary dynamics associated with this bistable system. The analysis yields important practical information on the timescales of equilibration.

Regularized Model of Post-Touchdown Configurations in Electrostatic MEMS: Equilibrium Analysis
In canonical models of Micro-Electro Mechanical Systems (MEMS), an event called touchdown whereby the electrical components of the device come into contact, is characterized by a blow up in the governing equations and a non-physical divergence of the electric field. In the present work, we propose novel regularized governing equations whose solutions remain finite at touchdown and exhibit addit...
متن کاملRegularized Model of Post - Touchdown Configurations in Electrostatic MEMS : Bistability Analysis
This paper considers the problem of stiction in electrostatic-elastic deflections whereby elastic surfaces adhere to one another after coming into physical contact under attracting Coulomb interactions. This phenomenon is studied in a family of recently derived models which account for forces which become important when the elastic surfaces are in close proximity. The presence of bistability in...
متن کاملAnalysis of the Dynamics and Touchdown in a Model of Electrostatic MEMS
We study a reaction-diffusion equation in a bounded domain in the plane, which is a mathematical model of an idealized electrostatically actuated microelectromechanical system (MEMS). A relevant feature in these systems is the “pull-in” or “jump-to contact” instability, which arises when applied voltages are increased beyond a critical value. In this situation, there is no longer a steady state...
متن کاملDynamics and Touchdown in Electrostatic MEMS
Perhaps the most widely known nonlinear phenomena in nanoand microelectromechanical systems is the “pull-in” or “jump-to-contact” instability. In this instability, when applied voltages are increased beyond a certain critical voltage there is no longer a steady-state configuration of the device where mechanical members remain separate. This instability affects the design of many devices. It may...

This paper is a continuation of [9], where we analyzed steady-states of the nonlinear parabolic problem ut = ∆u− λf(x) (1+u)2 on a bounded domain Ω of R with Dirichlet boundary conditions. This equation models a simple electrostatic Micro-Electromechanical System (MEMS) device consisting of a thin dielectric elastic membrane with boundary supported at 0 above a rigid ground plate located at −1....
