    Magnetic field interactions of smartwatches and portable electronic devices with CIEDs. Did we open a Pandora’s box?
    (Elsevier, 12/2022) Badertscher, Patrick; Vergne, Céline; Féry, Corentin; Mannhart, Diego; Quirin, Thomas; Osswald, Stefan; Kühne, Michael; Sticherling, Christian; Knecht, Stefan; Pascal, Joris [in: International Journal of Cardiology Heart & Vasculature]
    Magnetic interaction of portable electronic devices (PEDs), such as state-of-the art mobile phones, with cardiovascular implantable electronic devices (CIEDs) has been reported. The aim of the study was to quantify the magnetic fields of latest generation smartwatches and other PEDs and to evaluate and predict their risk of CIED interactions.

    Millirobot magnetic manipulation for ocular drug delivery with sub millimeter precision
    (IEEE, 2022) Vergne, Céline; Ignacio, Jose; Quirin, Thomas; Sargent, David; Pascal, Joris [in: 2022 IEEE Sensors]
    Significant progress has been made in the development of magnetic micromanipulation for minimally invasive surgery. The development of systems to localize millimetric size robots during magnetic navigation and without line of sight remains however a challenging task. In this study, we focused on the development of a tracking system aiming to fill this gap. A robot which consists of a cylindrical magnet of 1 mm diameter is localized using a 2D array of 3D magneto resistive sensors. The system provides a tracking of the robot with a refreshing rate of 2 Hz. The developed tracking algorithm reaches a mean absolute error for the position and the orientation of, respectively 0.56 mm and 5.13° in 2D. This system can be added to existing magnetic navigation systems allowing closed loop control of the navigation. The presented tracking system makes it possible to target applications such as minimally invasive ocular drug delivery.

    Towards tracking of deep brain stimulation electrodes using an integrated magnetometer
    (MDPI, 10.04.2021) Quirin, Thomas; Féry, Corentin; Vogel, Dorian; Vergne, Céline; Sarracanie, Mathieu; Salameh, Najat; Madec, Morgan; Hemm-Ode, Simone; Hebrard, Luc; Pascal, Joris [in: Sensors]
    This paper presents a tracking system using magnetometers, possibly integrable in a deep brain stimulation (DBS) electrode. DBS is a treatment for movement disorders where the position of the implant is of prime importance. Positioning challenges during the surgery could be addressed thanks to a magnetic tracking. The system proposed in this paper, complementary to existing procedures, has been designed to bridge preoperative clinical imaging with DBS surgery, allowing the surgeon to increase his/her control on the implantation trajectory. Here the magnetic source required for tracking consists of three coils, and is experimentally mapped. This mapping has been performed with an in-house three-dimensional magnetic camera. The system demonstrates how magnetometers integrated directly at the tip of a DBS electrode, might improve treatment by monitoring the position during and after the surgery. The three-dimensional operation without line of sight has been demonstrated using a reference obtained with magnetic resonance imaging (MRI) of a simplified brain model. We observed experimentally a mean absolute error of 1.35 mm and an Euclidean error of 3.07 mm. Several areas of improvement to target errors below 1 mm are also discussed.
