In the presented work the dynamic simulation of a silicon anodization process is performed. Two mechanisms of etch form development (diffusion in electrolyte, current flow) are considered and simulated. Influence of electrolyte conductivity and radius of the opening in the masking layer is discussed.

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 ...

Heat Generation from Dielectric Loss, Internal Heat Generation and Vibration in COMSOL4.2 Multiphysics
T. R. Jeba, B. Vins, and V. Ramamoorthy
This paper presents a FEA approach to estimate temperature rise and thermal stress experienced in PZT/Solid structure due to internal heat generation and dynamic excitation. The power dissipative density consumed by structural damping of the mass structure, internal heat generation due to applied voltage and dielectric loss of the PZT material is first determined. The dissipative power is then ...

In this paper, we have proposed an impedance biosensor based on polymer nanowire (made of polyaniline) for efficient electric field mediated capture of biomolecules. Existing polymer nanowire based biosensors fail to achieve high sensitivity for low surface to volume ratio as the whole length of the nanowire is exposed to the analyte .Also biosensors are dependent on diffusion mediated capture ...

Cantilever beam-type transducers have been in great demand and explored widely in the recent years, typically in thin film form because of their sensor and actuator applications. The piezoelectric cantilever is the most preferred structure employed in technological applications. Depending on the required flexural motion and sensitivities, these piezoelectric cantilevers can be used in unimorph, ...

In our recent experiments we are revisiting the topografiner technology for the imaging of surface topography with a resolution of a few nanometers. In these new technique called Near-Field Emission Scanning Electron Microscopy (NFESEM), low-energy electrons are emitted from a polycrystalline tungsten tip via electric-field assisted tunneling. In order to characterize and improve the ...

The integration of high level of stress in field effect transistors is performed through incorporation of intrinsically strained SiGe layers. With the help of COMSOL simulations, we performed two studies addressing the level of stress in the area of interest. In the first case, we analyzed the geometric effects of the SiGe film stress relaxation on the edges. In a second time, we studied the ...

A biotransformação de substratos utilizando enzimas imobilizadas em nanopartículas presentes num meio fluido (substrato), contido num bioreator CSTR, foi investigada. O software COMSOL Multiphysics foi usado para simular o sistema através do uso das equações de difusão de espécies apropriadas para o consumo do substrato. Nessa investigação, a difusão na superfície da nanopartícula, onde ocorre a ...

The conversion of mechanical energy from environmental vibrations into electrical energy is a key point for powering sensor nodes toward the development of autonomous sensor systems. Piezoelectric energy converters realized in a cantilever configuration are the most studied for this purpose. In order to improve the performances of the converter, the geometry has to be properly designed. In this ...
