Pull-in instability of cantilever and fixed–fixed nano-switches

Analytical modeling for the determination of nonlocal resonance frequencies of perforated nanobeams subjected to temperature-induced loads

“…Unlike the classical elasticity theory, nonlocal elasticity theory of Eringin [18][19][20] is a scale dependent theory accounts the nonlocal effects on resonance frequencies of simply supported beams at nanometric dimensions [21][22][23][24]. Nowadays, researchers have applied nonlocal elasticity theory for different materials [25][26][27][28][29][30] to predict linear and nonlinear [1,31] resonance frequency for uniform and nonuniform [32][33][34][35] nanostructures.…”

A novel mems charge-pump circuit

“…MEMS switches are surface-micro machined devices which use a mechanical movement to achieve a short circuit or an open circuit in the RF systems. RF MEMS switches are the specific micromechanical switches which are designed to operate for m 0.1 to 100 GHz [12]. With the recent exciting advancements in the field of miniaturized MEMS switch have shown to offer a superior RF performance in comparison to their semiconductor counterparts.…”

Surface effect on dynamic characteristics of the electrostatically nano-beam actuator

“…In recent years, nano-electromechanical system (NEMS) devices have been widely applied in a diverse range of applications, including nano-switches [1], ultrasensitive sensor [2] and RF communication modules [3] and others, and this certainly makes NEMS research a worthwhile field. When a driving voltage is applied between a moveable and a fixed structure, charges are induced on each which causes an electrostatic force to act on both structures.…”
