The modern world is heavily reliant on electromagnetic devices to convert mechanical energy into electrical energy and vice versa. These devices are fundamental to powering our society, and the growing need for automated production lines and electrified tr ...
EPFL2023Control of a polar order via magnetic field in a vector-chiral magnet
Vector-chiral (VC) antiferromagnetism is a spiral-like ordering of spins which may allow ferroelectricity to occur due to loss of space inversion symmetry. In this Letter we report direct experimental observation of ferroelectricity in the VC phase of beta ...
AMER PHYSICAL SOC2021Force and Torque Model of Ironless Passive Magnetic Bearing Structures
Yves Perriard, Douglas Martins Araujo, Leopoldo Rossini, Guzmán Borque Gallego
This article presents the development and validation of a three-dimensional force and torque semi-analytical model for ironless permanent magnet structures. This method relies on the definition of the magnetic flux density generated by permanent magnets in ...
IEEE2019Permanent Magnet-Assisted Omnidirectional Ball Drive
Pierre Dillenbourg, Wafa Monia Benkaouar Johal, Ayberk Özgür
We present an omnidirectional ball wheel drive design that utilizes a permanent magnet as the drive roller to generate the contact force. Particularly interesting for novel human-mobile robot interaction scenarios where the users are expected to physically ...

Yves Leterrier, Ayat Karimi, Tommaso Nardi
In order to mimic the complex architecture of many bio-materials and synthesize composites characterized by continuously graded composition and mechanical properties, an innovative synthetic strategy making use of magnetic field gradients and based on the ...
2014Integrated Hall Magnetic Angle Sensors
A magnetic angle sensor is a matched combination of a permanent magnet, affixed to a rotating shaft, and a magnetic field sensor. The magnet part of the angle sensors is configured so as to create either a magnetic field with an angle-dependent component p ...
Soc Microelectronics, Electron Components Materials-Midem2014Magnetic Stationary Phases for Protein Adsorption
Magnetic beads (MB) have now proven to be a powerful tool in both research and biomedical applications. They are available in a wide range of sizes (from nm to several µm) and their surface can be modified with molecules having biological specificities and ...
EPFL2011Ring magnets for magnetic beads trapping in a capillary
Hubert Girault, Anne-Laure Gassner
This paper introduces the concept of ring magnets for magnetic beads (MBs) trapping in a capillary. Such magnets enable an easy insertion of a capillary simply like a pearl on a string. With this system, high magnetic forces are obtained thanks to the prox ...
