Dielectrophoresis (DEP) is a method for cell manipulation without physical contact in lab-on-chip devices, since it exploits the dielectric properties of cells suspended in a microfluidic sample, under the action of locally generated high-gradient electric fields. The DEP platform that has been developed offers an integrated solution for customizable applications. Several functional units, ...

In this work, the process of micro-channels in electrochemical micro-milling by using rotating magnet assisted helical tool is presented. The results show helical tool and Lorentz force of the rotating magnetic field that enhance the renewal of the electrolyte and machining efficiency. The feed rate can be raised under the magnetic field assisted in terms of experimental results; moreover, the ...

Linear motor has a lot of applications, such as magnetic levitation train, electromagnetic weapons. It is a very important research significance. We established a three-dimensional model of linear motor to calculate the magnetic field lines and flux density distribution, and got the electromagnetic force too. We compared the results of simulation using COMSOL and experiment under different ...

The silicon cantilever with the planar coil was applied to the magnetic flux density measurements. The influence of shape and dimensions of planar coil on magnetic energy density was described. In cause of magnetic anisotropy of analyzed silicon structure FEM method and couple field method was applied in simulation. The Lorentz force based sensors owing to their potentially simpler fabrication ...

Electrofluidic transport through a single walled carbon nanotube (SWCNT) is enhanced by electroosmosis. Electroosmosis is made possible in these devices by the combination of a large slip length within SWCNTs and the interfacial potential at the solution/nanotube interface. A computational model of a SWCNT device was developed using COMSOL Multiphysics to investigate the complete electrical ...

New giant piezoelectric factor materials such as PMN-PT and PZN-PT were researched during the last decade and are actually becoming commercially available. As they seem very attractive for actuator designs, we studied their potential in replacing PZT ceramics. In a first comparative approach, we tested a series of classic rectangular composite bimorph structures of different combinations of ...

Two mathematical models of the electrokinetic flow are presented where the electroosmotic flow is induced by the interaction of a surface electric charge with a perpendicularly imposed electric field. In order to solve such problems, an anisotropic mesh of rectangular finite elements is developed. Stationary distributions of the model variables are computed for various sets of model ...

In “Micro-Electro-Mechanical-Systems” shortly known as MEMS, one of the most important and effective principle of creating transduction of electrical power to displacement force is thermal expansion. A slim beam of MEMS material, typically Silicon, is heated by the application of electrical current via Joule heating; it expands and creates motion. In the design of many MEMS devices ...

In the model silicon nanorods are designed as cantilever array and coated with thin film of aluminum or aluminum nitride, to be characterized, thus, adding a detectable mass and altering the cantilever resistance to bending. The simulated results show that when films of different thickness are placed on the cantilever, there is a corresponding change in the resonant frequency and the ...
