The mechanical simulation and analysis of the cantilever-to-anchor configuration for an out-of-plane structure used in transducer applications is reported. The polymer-based Buckled Cantilever Plate “BCP” structure, gives the ability to orient an active device from a horizontal to a vertical position, once assembled. In this paper we compare four different cantilever-to-anchor configurations: ...

In this paper we present results of the mathematical modeling of AC electroosmotic micropumps. Unlike others we use the full dynamic description, instead of the linearized model. Skewed hybrid discretization meshes are employed in order to accurately capture the main features of the studied system. Also, we introduce zig-zag electrode arrangements for traveling-wave electroosmotic micropumps. ...

This paper will describe the dependence of capacitive accelerometer characteristics on the accelerometers physical dimension and its material properties. The sense element of the accelerometer is designed on the basis of a commercially available torsion based accelerometer technology. The sense element consists of an asymmetrically shaped flat plate of metal supported above a substrate surface ...

Low-dimensional semiconductor nanostructures, in which charge carriers are confined in a number of spatial dimensions, are the focus of much solid-state physics research, offering superior optical and electronic properties over their bulk counterparts. Both two-dimensional (2D) and zero-dimensional (0D) structures have seen wide-ranging applications in laser diodes, solar cells and LEDs to name ...

Relief patterning of the surface of microchannels has been actively pursued as a method of promoting mixing in systems with a low Reynold’s number (<<100). In this work, we explore, by using the COMSOL Multiphysics package and its Chemical Engineering Module, the possibility of enhancing the mixing quality of two fluids in a microchannel with a non-periodic fractal pattern of ridges ...

The paper presents recent results concerning the experimental mechanical characterization, the numerical modeling and the design of micro-needles used in the construction of probe heads for wafer testing. A fully coupled electro-thermal model was created using COMSOL and combined to a research-oriented thermo-mechanical Finite Element (FE) code in order to accurately reproduce the micro-needle ...

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 current paper focuses on the creation of a consistent environment for the numerical prediction of the physical properties of polymer composite. A limitation factor for the successful simulation of composite processes is the correct estimation of the effective properties depending on several factors such as the constituents (fiber, polymer), the process setup. The numerical prediction of the ...

Introdução: A medição adequada de vazão de fluidos é de grande importância nos processos industriais, pois tem implicações diretas na qualidade, produtividade, segurança e eficiência dos processos. Assim, torna-se necessário compreendermos como os fluidos se comportam para baixas velocidades, podendo, dessa forma, projetar estruturas que possam trabalhar em uma faixa de operação mais larga ou ...
