Continuous Real-Time Inductive Tracking of Magnetic Microagents for Closed-Loop Control

Abstract

Magnetic microagents hold great promise for improved medical treatments, including targeted drug delivery. Yet, tracking position and performance in vivo during actuation remains challenging. We introduce a sensing approach leveraging inductive signals derived from microagents actuated by a rotating magnetic field (RMF). This offers the unique possibility of controlling microagents while simultaneously tracking position and phase lag in real-time.
