The research presented here shows a multiphysics model for a polymerelectrolyte transistor (PET) simulated in COMSOL Multiphysics.Dynamic transient response and current-voltage characteristics are determined from multiple simulations of an alkaline-acid-alkaline PET in a common collector configuration, showing transistor activity in the ionic currents of the device. This shows that increasing ...

The development and analysis of interconnects in inhomogeneous structures such as very large scale integration chips, printed circuit boards, and multichip modules are essential for next-generation electronic products. In this paper, we illustrate fast and sufficiently accurate computation of capacitance matrices of multilayered and multiconductor interconnects applying the finite element ...

The field quality requirements of most particle accelerator magnets are very tight and, therefore, very precise simulations are needed to accurately calculate these devices. CERN\'s ROXIE code is widely used as a reference software to calculate normal conducting and superconducting magnets for particle accelerator applications. ROXIE uses the full vector potential coupled to the BEM-FEM method ...

In our experiments with manipulating cells with DEP, we noted that some cells are constantly spining. By hypothesing that the cell spining is caused by the non-circular shape of the cell body and the off-centered location of its nucleus and that the rotation direction depends on the relative location of nucleus with respect to the electrical field, we found that the observed cell rotation was ...

Contact electro-thermal phenomena are of great theoretical and technological interest to a large number of processing applications, such as spot welding, current-assisted sintering, electrical circuitry (switches) and motors. A model has been developed, aiming at predicting physical and metallurgical phenomena in a steel sample upon rapid heating induced by current pulse discharge. Electric pulse ...

Ferroelectric technology continues to attract significant interest due to its wide range of applications (capacitors, nonvolatile memories, accelerometers ...). In this work we present a finite element model of a ferroelectric. Piezoelectric and ferroelectric matrix are included. The coupling between the piezoelectric and ferroelectric parameters be introduced formally using a thermodynamic ...

State of the art proximity sensors are most often based on optical or tactile methods. Although these sensor systems are widely used (e.g. clamping protection) the reveal several drawbacks. Most optical sensors need a line of side whereas tactile sensors cannot be used to determine a distance to an approaching object. Capacitive sensing technology has proven to be an interesting alternative to ...

Introduction: Medium voltage reclosers are representing nowadays an important link between transmission power systems and low voltage grids. With a high level of renewable energy penetration, the medium voltage networks are becoming bidirectional. Therefore, the associated switching devices must ensure the protection of newer types of power systems as well as new types of loads. The optimal ...

In this paper an attempt has been made to design and analyze integrated circuit interconnects for unshielded four conductors with three levels system using Finite Element Method (FEM). The computational and simulation work has been carried out with help of COMSOL Multiphysics software. We illustrate that FEM is as accurate and effective for modeling multilayered multiconductor transmission lines ...
