In order to design an RF MEMS based device, it is beneficial to have information concerning mechanical behavior. For model verification purpose, solution offered by simulation software equipped with predefined physics application is one valuable way to provide initial reference. To avoid unwanted particular total strain in RF MEMS structures, a compensation layer can be utilized. When the number ...

A clothing system should offer the user a period of relatively comfort. However, changes in the ambient conditions over day affect the heat and mass transport in the system, influencing the user comfort perception. In order to gather information to allow the optimization of clothing systems, it is essential to understand the heat and moisture transfer occurring across multi-layer textiles. For ...

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: ...

The hydraulic flocculates are employed in water treatment plants (WTPs), but may present problems during the mixing stage reducing the efficiency of treatment. In this context modeling of a hydraulic flocculate using COMSOL and a 1:10 scale model of the Maringá-PR Brazil city WTP flocculate was done. The WTP flocculate is shown in figure 1 and the model illustrating the acrylic flocculate ...

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 ...

Considering a liquid drop in relative movement with respect to the air flow at uniform velocity, the liquid will be driven to the surface by the viscous friction. Internal vortices will appear inside the drop. This problem has already been studied in fluid mechanics and is well known as a classic problem. The idea of the present work is to resume the same analysis in a porous medium within a ...

Polishing is one of the oldest finishing processes. However, exposure to emissions of crystalline silica dust is high. Some toxicological studies have identified this pollutant as responsible for a particular type of lung cancer, silicosis. Operational solutions are needed for reducing near-field emissions of fine and ultrafine dust. Granite dust is emitted at high concentrations during ...

Designing and constructing a lab-on-a-chip device poses a variety of questions. Transport of all required substances, detection of the analyte and its deposition on a sensor have to be incorporated. Different strategies have been developed to achieve good coverages of the sensor, like employing electric or magnetic gradients. On the basis of a ramp like structure, the binding of the analyte to a ...

Microdialysis is a technique of continuous glucose monitoring in diabetic patients. In microdialysis, a saline serum is perfused into a microdialysis probe. Glucose pass from the plasmatic fluid through the porous membrane. The glucose concentration in the dialysate obtained is measured by an external analytical device. This preliminary work aimed to obtain a model to relate glucose ...
