The gigantic magnitude features of the ionic current of electrolyte through carbon nanotubes (CNT) are explained by the dramatic increase of electroosmotic current induced by the strong slip at the CNT surface and the considerable excess volume charge inside the tube. In this study, we investigate the fundamental details of gating phenomena of such gigantic ionic current through CNT by using ...

In this work a cantilever beam has been chosen as the element of study, consisting of a piezoelectric polymer like PVDF with a thin permalloy layer coating on one side of it. This piezoelectric cantilever is designed using COMSOL software. It is seen that the deflection of the tip of a unimorph cantilever is dependent on its geometric dimension, type of material and the applied field. Hence in ...

This paper presents a novel design of a RF MEMS Switch. The switch is a capacitive type, which is actuated by an electrostatic force. The structure of the switch consists of a CPW (coplanar waveguides) transmission lines and a suspended membrane. The modelling of switch is done using COMSOL software and RF characteristics is found out by using CST software.

Laser-driven micromachines using total internal reflection were developed by using two-photon microfabrication. The optical torque exerted on the micromachine was evaluated by COMSOL Multiphysics software. The laser-driven micromachines will be applied to lab-on-a-chip devices.

Previous works on MEMS actuated Fabry-Perot interferometer (FPI) highlighted promising results for flexible display applications. Three primary color pixels have indeed been obtained using both photolithography and Roll-to-Roll printing process with satisfying color purity and transmittance. However both of these processes are expensive and time-consuming for preparing micropatterns. For these ...

We have simulated a capacitive MEMS switch for application to Coplanar Waveguide (CPW) circuits using COMSOL Multiphysics. The switch configuration involves a pair of metal bridges over the CPW line designed for operation in the Ka - Band frequencies. It is shown that the operating frequency of the switch can be tuned by adjusting the gap between the two bridges. Estimation of the switch ...
