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, ...

Investigation in this paper aims at performing Mechanical Stress Strain analysis, Thermal, Piezoresistive and Piezoeletric analysis of Silicon Structures using COMSOL. The simulation results have been cross checked by mathematical calculation.
In recent years, optical manipulation using optical radiation pressure has been widely studied. In this study, the radiation pressure exerted on various kinds of microscopic objects with different laser beams was evaluated by COMSOL Multiphysics software. By changing beam shapes, microscopic objects can be trapped and rotated. This paper is in Japanese.

The paper brings out the designing and implementation of blood viscosity monitoring device that gives us the INR to measure the effectiveness of anti coagulant medications .When a blood vessel is damaged, clotting cascade begins that results in blood clot. This process is affected by several medical conditions where it becomes mandatory for a patient to intake anti-coagulants. Thus to monitor ...

The Micro electro mechanical systems (MEMS) technology provides us a platform to interface between mechanical and electrical components. In this paper, we have designed MEMS accelerometer based on piezoelectric property, and simulated using COMSOL Multiphysics®. The design, which has PZT kept in the annular diaphragm, provides good sensitivity. When this accelerometer is subjected to stress ...

Cells are complex entities which not only passively sense external stimuli (viz. chemical, optical or mechanical) but also interact with extracellular matrix (ECM) by regulating cellular behavior such as growth, proliferation, migration, etc. Monitoring cell growth and migration of adherent cells becomes a crucial factor in determining cell-cell and cell-substrate interaction, important for ...

Large deflection actuators are becoming increasingly important for microsystems. Since actuation forces are usually small, large deflection actuators usually require flexures with low stiffness. Rectangular serpentine flexures are often used for such actuators due to their low stiffness and large linear deflection range. In this paper we investigate the performance of curved serpentine flexures ...

Electromagnetic micro valves are currently developed empirically or the different physics are treated separately. To accelerate the development-process and for a better understanding of the overall system, a multiphysics simulation is built up. This simulation considers the electromagnetics, the electronics (including the control of the process), the mechanics and the fluidics with respect to the ...

A surface acoustic wave (SAW) device consists of a piezoelectric material (or film) on which interdigitated transducers (IDT) are placed. Here, they are analyzed based on PZT-5H wurtzite ceramics and InSb zincblende crystals. In PZT-5H, it is possible to generate SAW’s by aligning the interdigitated transducers (IDT) with the crystal axes. In the case with InSb zincblende structures ...
