Electroceutical Modeling with Advanced COMSOL® Techniques
Neuromodulation is the use of electromagnetic fields to modulate the human nervous system, typically to treat neurological disorders. Electroceuticals is an ambitious program to modulate any nerve, anywhere, anytime, for any reason — to treat disease, disorders, and enhance or interface ... En savoir plus
Modeling of Electro-Thermal Microbolometer for Thermal Imaging
A Microbolometer is a specific type of uncooled infrared radiation detector used in thermal cameras, which converts the incoming energy into a proportionate electrical signal, which is then amplified, processed and displayed, typically on the thermal camera’s LCD viewer. The main ... En savoir plus
Multiphysics Simulation of Micro-Thermoelectric Generators Based on Power Factor Optimized Materials
Thermoelectric generators (TEGs) which convert heat into electrical energy due to Seebeck effect, have recently attracted a great attention as green and sustainable energy sources.

Computational Study on Transcutaneous Frontal Nerve Stimulation: Simplification of Human Head Model
I. INTRODUCTION Migraine is a neurological disorder which affects nearly 15% of the population and it has been estimated that the European Community spends about €27 billion in a year. Its symptoms may be categorized as attacks of often severe, throbbing head pain with sensory ... En savoir plus
Polynomial-Chaos Uncertainty Modeling in Eddy-Current Inspection of Cracks
In the context of non-destructive evaluation methods, eddy-current testing plays a prominent role in crack-detection problems, due to its various attractive features. One of the physical quantities that typically interest us in such type of problems is the – complex – coil impedance and ... En savoir plus
Numerical Calculation of the Three Dimensional Inter-Bar Current Distribution in Induction Machines
The calculation of additional losses in induction machines is a challenging task. In skewed motors, a part of these losses is connected to the phenomena of inter-bar currents. Inter-bar currents flow between adjacent bars through the rotor lamination. Since they are aligned perpendicular ... En savoir plus
Simulation of Eddy Current Non Destructive Testing using COMSOL Multiphysics®
Nondestructive Testing (NDT) refers to a wide group of methods used in industry to evaluate the properties of a material, component or system without causing damage. These include radiography, ultrasound, electromagnetic and visual, among others. Eddy-current testing (ECT) is one such ... En savoir plus
Multiphysical Simulation of an Induction Sealing Process for Cups with Laminated Aluminum Foil
The filling process of thermoformed cups with food like yogurt is followed by placing a laminated aluminum foil for hermetic sealing on top of the cup. By today’s standards the sealing of the thermoformed aluminum foil with the cup is primarily realized by contact heat with a hot stamp. ... En savoir plus
