Electromechanical Performance of Nems Actuator Fabricated From Nanowire Under Quantum Vacuum Fluctuations Using Gdq and Mvim

The casimir attraction can significantly interfere the physical response of nanoactuators. the intensity of the casimir force depends on the geometries of interacting bodies. the present paper is dedicated to model the influence of the casimir attraction on the electrostatic stability of nanoactuators made of cylindrical conductive nanowire/nanotube. an asymptotic solution, based on pathintegral approach, is employed to consider the casimir force. the continuum theory is employed to derive the constitutive equation of the actuator. the governing nonlinear equations are solved by three different approaches. various perspectives of the issue including comparison with the van der waals (vdw) force regime, the variation of instability parameters and effect of geometry are addressed.
