4. Computational modelling of human forearm perception thresholds in magnetic stimulation

Low-frequency magnetic fields induce internal electric fields in the body. When these fields are sufficiently strong, they can stimulate nerves, causing muscle contractions or sensory perceptions. Electrostimulation models, which consider the spatial and temporal characteristics of the induced electric field, can be used to determine nerve and muscle excitation thresholds. However, these...

This study aims to investigate the impact of high-intensity power-frequency magnetic fields (MF) on cardiac implantable electronic devices (CIEDs), particularly in workplace environments with strong electromagnetic fields (EMFs). While theoretical models and numerical studies have assessed interference risks, limited experimental approach exists. In this work, we have developed an experimental...

This study investigates the effects of electric fields on red blood cell (RBC) movement in whole blood, focusing on simulating realistic exposure conditions. It is part of a broader effort to elucidate the biological effects of extremely low frequency (ELF) electric fields and understand their impact on living systems. In previous work, we demonstrated that electric fields significantly...

7. Robust Assessment of the Incident Field at the Surface of Wireless Power Transfer Devices

Inductive wireless power transfer (WPT) systems use magnetic fields to transfer power between a transmitter and a receiver; the receiver is typically integrated into a device with a battery to be charged, e.g., in smartphones or electric vehicles. The highest fields, which are typically generated at the surface or in locations closest to the coils of these devices, decay rapidly as a function...

8. EMF Safety Assessment of a Dynamic Wireless Power Transfer System for e-Mobility

In this study, the electromagnetic field (EMF) safety assessment of a dynamic wireless power transfer (DWPT) system during charging operations of a moving compact electric vehicle (EV) is evaluated. Specifically, different positions of the DWPT coils that account for the in-motion EV are considered for both aligned and misaligned configurations. Compliance with international safety standards...

9. Impact of Face-Down MR Examination on RF Heating of Medical Implants

The aim of this work is to assess the impact of face-down, or prone, posture during MR examination on the RF-induced heating of medical implants. As face-down postures during MR examination, used for breast as well as some wrist and elbow imaging scenarios, may lead to different induced electrical field distributions, the resulting RF-induced power deposition may also change dramatically. To...
