- •
The pull-in instability of the NEMS bridge immersed in ionic liquid electrolyte media is explored for the first time.
- •
The dispersion forces are included in the model considering the three layer interaction.
- •
The strain gradient elasticity is employed to incorporate the effect of size-dependency and beam stretching.
- •
To solve the constitutive equation of the system the differential transformation method (DTM) and numerical solution are employed.
