Ionic Neuromodulation and Neurosensing Platform for In Vitro Studies
Overview We successfully simulated a template iontronic system for closed-loop neuromodulation and neurosensing. The model’s goal is to support the careful design of novel platforms for in-vitro micro-electrode-array sensors coupled to conductive polymer-based (CP) ionic actuators used ... En savoir plus
Modeling of Thermal Load and Electric Fields in Microfocus X-Ray Tubes
The thermal load on the system components is one of the technical problems in the development of microfocus X-ray tubes. To improve their stability in long-term use, it is important to understand the physical phenomena and their influence on the system stability and filament lifetime. To ... En savoir plus
High Speed Inductive eRPS Sensor Error Reduction Using COMSOL Multiphysics®
Modern electrical vehicle motors require a precise current control over the rotation of the rotor. These motors have high performance, but their control requirement impose a precise knowledge of the rotor angular position. Rotor position sensor (RPS) are traditionally designed using ...

Electromagnetic Simulation of High-Temperature Superconductors
High-temperature superconductor (HTS) technology is more and more commercially exploited, mainly for nuclear fusion reactors. The demand for HTS tape is met by multiple commercial manufacturers; there is a mature production process. With this technology now available, some other ... En savoir plus
Shielding of Magnetic Fields of an Electrical Substation
Normally, power lines for electrical power distribution are shielded such that there is (almost) no magnetic field outside the cable. In a substation, these cables are connected to transformers via unshielded components such as switching boards and busbars. Thus, magnetic fields are ... En savoir plus
The Counterintuitive Physics Behind Magnetically Levitated Hoverboards
The following set of COMSOL® simulations were a vital part of a multi-year-long research project about magnetically levitated hoverboards. A hoverboard can be seen as a small skateboard, that uses magnetic a set of hover-thrusters instead of wheels. A total of nine working prototype ... En savoir plus
Modeling PCB Based Inductive Position Sensors with the COMSOL® AC/DC Module
The growing adoption of electric vehicles has led to increased exposure of cars to stray magnetic fields. To address this issue, inductive position sensors have emerged as a viable solution due to their inherent immunity to stray magnetic fields. Widespread adoption of the inductive ... En savoir plus
Fluxgate Virtual Current Sensor
The paper describes how the fluxgate current sensor works and how it is built in the COMSOL Multiphysics® software. Four COMSOL® modules were used: -AC/DC Module: the magnetic field physic is used in order to apply the Ampere-Maxwell’s law to the different sensor components and to the ... En savoir plus
Modeling of Droplet Charge Dynamics During an Ink Jet Breakup Using COMSOL Multiphysics®
Continuous Ink Jet (CIJ) printing technologies are widely used in the field of industrial coding and marking. These technologies are based on the emission of a high-speed jet of ink droplets (20 m/s) onto the surface of a moving medium. To maintain sufficient print quality, it is ... En savoir plus
Computational Modeling of Plasma Using Single-Fluid and Two-Fluid Modeling Approaches
Plasma, a complex fluid consisting of electrons, ions, neutrals, and excited species, exhibits both fluid-like behavior and electrical conductivity due to the presence of charge carriers. Consequently, computational modeling of plasma requires the integration of fluid and electrical ... En savoir plus
