Tri-axial H-Field Sensor with Frequency-shaped Response in the band 400 MHz - 6 GHz

This contribution presents an isotropic field probe to assess human exposition to broadband magnetic fields in the 400 MHz to 6 GHz band according to the ICNIRP 2020 guidelines. This device complements the current practice in this band, based on the measur ...

Capacitive sensor to monitor the level of drug inside an injector pen

Sylvain Paul Fernand Joly

Diabete is a disease which is spreading faster than ever, impacting now a larger population. Patients suffering from this disease need the injection of insulin to control extracellular sugar levels. Pharmaceutical companies developed injector pens to allow ...

Optimization of the fabrication of buried electrodes for NEMS resonators

The aim of this project is to optimize the fabrication of buried lateral electrodes, with a piezolectric material sandwiched between two metal electrodes. Lateral electrodes have the advantage of allowing the applied electric field to be and to remain comp ...

A stability theory beyond the co-rotational setting for critical wave maps blow up

Joachim Krieger, Shuang Miao

We exhibit non-equivariant perturbations of the blowup solutions constructed in [18] for energy critical wave maps into

\mathbb{S}^2

. Our admissible class of perturbations is an open set in some sufficiently smooth topology and vanishes near the light co ...

Improved measurement of electric fields by nanobeam precession electron diffraction

Jean-Luc Rouvière

The electric field in a silicon p-n junction has been measured using pixelated scanning transmission electron microscopy. By using a convergence angle of 3.2mrad, a spatial resolution better than 1nm can be achieved leading to a rigid shift of the transmit ...

Electric-field control of single-molecule tautomerization

Klaus Kern, Christian Alexander Stephan Dette, Shai Mangel, Katharina Polyudov, Tobias Wollandt

The electric field is an important parameter to vary in a single-molecule experiment, because it can directly affect the charge distribution around the molecule. Yet, performing such an experiment with a well-defined electric field for a model chemical rea ...

Effect of input voltage frequency on the distribution of electrical stresses on the cell surface based on single-cell dielectrophoresis analysis

Philippe Renaud, Hanie Kavand

Electroporation is defined as cell membrane permeabilization under the application of electric fields. The mechanism of hydrophilic pore formation is not yet well understood. When cells are exposed to electric fields, electrical stresses act on their surfa ...

Towards the material limit and field concentration smoothing in multilayer dielectric elastomer actuators

Yves Perriard, Yoan René Cyrille Civet, Jonathan André Jean-Marie Chavanne, Morgan Almanza

Performance of dielectric elastomer actuators is closely related to its breakdown field. On the other hand, to enhance the available energy, multilayer configuration is needed to increase the amount of active material. However, multilayer configuration suf ...

Novel Slanted Field Plate Technology for GaN HEMTs by Grayscale Lithography on Flowable Oxide

Elison de Nazareth Matioli, Jun Ma, Luca Nela, Taifang Wang

We report a novel process to achieve slanted field plate (S-FP), which is a field plate with a gradual increase thickness from gate edge towards drain - utilizing grayscale lithography on flowable oxide (FOX) in single process step, in which developed FOX ...

Eigenmode Analysis in Plasmonics: Application to Second Harmonic Generation and Electron Energy Loss Spectroscopy

Gabriel David Bernasconi

Eigenmodes are central to the study of resonant phenomena in all areas of physics. However, their use in nano-optics seems to have been hindered and delayed for various reasons. First, due to their small size, the response of nanostructures to a far-field ...
