Abstract

Magnetic microrobots are investigated for minimally invasive applications, but their use remains limited by the lack of robust localization methods. An impedance-based sensing platform using a multiplexed electrode array is presented for spatial localization and tracking of a conductive magnetic milli-gripper in physiological saline solution. Experimental results demonstrate localized impedance variations that shift consistently with milli-gripper position across electrode pairs. Continuous measurements further enable real-time tracking during controlled displacement inside the sensing chamber.
