Abstract :
It is well recognized that size-e ect often plays a signi cant role in the
mechanical performance of nano-structures. Herein, strain gradient continuum elasticity
is employed to investigate the size dependent pull-in instability of the cantilever nanoactuators
immersed in ionic liquid electrolyte. The presence of dispersion forces, i.e.
Casimir and van der Waals eld, is considered in the theoretical model as well as the
double-layer electrochemical attraction. To solve the non-linear constitutive equation of
the system, two approaches, i.e. the Rayleigh Ritz Method (RRM) and the numerical
solution method, are employed. Impact of the size dependency and dispersion forces on the
instability characteristics are discussed as well as the e ect of ion concentration in liquid.
