Moving nanowires through microfluidic channels under electrokinetic forces can be a valuable technique to aid in the fabrication of certain devices. The trajectories of a nanowire under the influence of an externally applied electric field have been modelled through a straight channel, through a converging channel, and around a 90° corner. In a straight channel, a nanowire initially ...

Continuous forming and propagation of large planar deformations on a thin solid elastic film can create propulsion when the film is immersed in a fluid. In this work, we present a numerical analysis of the effect of traveling plane-wave deformations on an elastic-film actuator within a fluid medium inside a channel. In particular, we analyzed a micropump that consists of a wave actuator. ...

The impedance based biosensor utilizes the electrical impedance measurements between interdigitated electrodes integrated into a microchannel containing the target cells in a suspension medium. The detection is based on measuring the change in impedance caused by the presence of bacteria. In this paper we describe the simulation of impedance measurements using the electromagnetics module of ...

The micromixer is one of the important components of Lab-On-a-Chip, but where the molecular diffusion, which is often a slow process, limits the mixing efficiency of two or more streams due to the unique laminar flows in these micro scale devices. This paper studies a mixing concept based on a vibrating micro-plate in the microfluidic channels to achieve an efficient mixing ability. A ...

Efficient, effective, and functional operation of autonomous systems requires a comprehensive real-time understanding, by those systems, of the embedding environment. This paper presents a brief overview of the multiphysics considerations involved in the development of models for thermoresistive and magnetoresistive sensors systems.

Induced Charge Electroosmosis (ICEO) refers to a fluid flow phenomenon in which an electric field induces a charge cloud (electric double layer) on a polarizable surface and sets up a tangential electric field to move this charge cloud along the surface, which in turn causes a fluid flow pattern. In our case, we considered nonlinear effects such as nonlinear capacitance, surface conduction, ...

In this paper a transient analysis of the thermoelastic contact problem for disk brakes with frictional heat generation is performed using the finite element analysis (FEA) method. The computational results are presented for the distribution of the temperature on the friction surface between the contacting bodies (the disk and the pad). Also, the influence of the material properties on the ...
