In this paper, a methodology to simulate the electric behavior of spiral inductances is presented and discussed. All the methodology is built with the COMSOL software used with the Matlab scripting interface and then allows performing fully parameterized simulations. The program architecture is explained and is used to simulate two applications. The first calculates the voltage induced by an ...

This paper gives an overview of modelling microsensors on geometry and system level. The focus will be on the generation of the multiphysics reduced order system model and the coupling with package and ASIC models. The method is based on modal superposition. This means all the details of the sensor can be considered in a finite element model. The mechanical mode shapes of this model form the ...

In this study, a detailed finite element model coupling the motion dynamics and electromagnetics of a diaphragm based MEMS vibration energy harvester is presented. The energy harvester converts low frequency vibrations to high frequency response by magnetic actuation of a diaphragm carrying coils. AC/DC, Solid Mechanics and Moving Mesh (ALE) modules are coupled together in one 3-D model to ...

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 ...
This paper covers the following: * All-Optical Light Modulation of surface plasmon polaritons (SPPs) is achieved using asymmetric single nanoslits. A high on/off switching ratio of >20 dB and phase variation of >? were observed with the device lateral dimension of only about 2 ?m. * Efficient unidirectional excitation of SPP as well as beam splitting are achieved using the ...

Nanoscale structural analysis and design is presented. All the simulations are carried out using a finite element solver and optimization is performed using parameter and topology optimization schemes. It is concluded that COMSOL is effective for analysis and design of nanoscale structure design in electromagnetic field and it may be combined with several optimization methods to improve system ...

The BioMEMS (Bio-Electro-Mechanical Systems) have become of considerable interest because they constitute a converging solution for many pluridisciplinary studies. The different covered fields are the biology (single cell, proteins, enzymes, neurons…), the chemistry (polymers), microelectronics and the microtechnologies associated with. Devices whose aim is the study of biological entities are ...

The evaporation process of microscopic drops was investigated by depositing them onto atomic force microscope (AFM) cantilevers and measuring the deflection of the cantilever in response to the presence of the drop. We could thus improve a previously presented FE simulation model by comparing the simulations of the cantilever’s transversal deflection to 3-D images of the cantilever’s ...

COMSOL Multiphysics has been used to study the effect of different heater design parameters on the temperature distribution in a chemical microreactor. The primary objective of the simulations has been to optimize the temperature uniformity inside the reaction chamber. In the simulations, special attention has been given to how the number, positions and widths of the heater strips relate ...

With their small size, low manufacturing cost, fast transient response, and capacity to generate fluid power directly from small electrical power sources, microdevices incorporating electroosmostic flow (EOF) have wide-ranging applications, including newly developed high-performance bioassay systems suitable for use in resource-limited settings. We report on a class of EOF-based devices called ...
