    Experimental assessment of the performances of an anisotropic magnetoresistive sensor after exposure to strong magnetic fields
    (IEEE, 2023) Vergne, Céline; Nicolas, Hugo; Madec, Morgan; Hemm-Ode, Simone; Guzman, Raphael; Pascal, Joris [in: 2023 IEEE International Magnetic Conference - Short Papers (INTERMAG Short Papers)]
    On-chip magnetometers are already integrated within long-term implants such as cardiac implantable electronic devices. They are also good candidates to be integrated within the next generations of brain stimulation electrodes to provide their position and orientation. In all cases, long-term implants are expected to be at least certified as MRI conditional. We investigated the resilience to the exposure to 3 T and 7 T of an anisotropic magnetoresistive sensor integrating a set/reset function. The sensitivity, non-linearity, and offset of a batch of 63 identical sensors were not affected by the exposure. These preliminary results provide new insights on the usability of magnetoresistive sensors for biomedical applications requiring MRI conditionality.

    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.
