Multiphysics Analysis and Optimization of Mechatronic Device Applications for Switching Devices

O. Cracium[1]
[1]ABB, Ladenburg, Germany

Medium- and high-voltage circuit breakers and reclosers are important grid protection devices that connect different grid sources and increase the network/grid reliability. Currently, there is a clear need of increasing the numbers of switching operation. Therefore, the optimal design of ... Mehr lesen

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 ... Mehr lesen

Determination of NFC-Antenna Operating Distance by COMSOL Multiphysics® Simulation of Planar Transformer Modeling

A. K. Palit [1],
[1] ZF-Lemförder Electronic GmbH, Espelkamp, Germany

Although the Near Field Communication (NFC) concept has been developed for the short distance communication between the NFC-reader antenna and transponder/Tag, yet the requirements of different Automotive OEMs vary drastically. For instance, for the keyless entry into the car based on ... Mehr lesen

Electric Field Density Distribution for Cochlear Implant Electrodes

N.S. Lawand[1], J. van Driel[2], P.J. French[2]
[1]Electronic Instrumentation Laboratory (EILab), Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS), Delft University of Technology, Delft, The Netherlands
[2]Delft University of Technology, Delft, The Netherlands

Cochlear Implants are implantable devices which bypasses the non-functional inner ear and directly stimulates the hearing nerve with electric currents thus enabling deaf people to experience sound again. Implant electrode array design is limited in electrode count, due to their large ... Mehr lesen

A Field Simulator for Permanent Magnet Applications

E. Ledwosinska [1], J. Gammel [1]
[1] Silicon Labs, Austin, TX, USA

Permanent magnets are ubiquitous in our world today, from refrigerator magnets to industrial sensor applications. Often, the magnitude of the field at a specific distance from an arbitrarily shaped magnet of variable strength is a necessary parameter for end-use systems. We used the the ... Mehr lesen

Electron Trajectories in Scanning Field-Emission Microscopy

H. Cabrera [1],
[1] Swiss Federal Institute of Technology, Zurich, Switzerland

The Scanning Field Emission Microscopy (SFEM) is a novel technology similar to the better known Scanning Tunneling Microscopy (STM). In STM, electrons are exchanged between the outermost atom of a sharp tip and the outermost atom of a target over sub-nanometer distances by means of the ... Mehr lesen
