Implantable magnetic sensing offers a route to wireless physiological monitoring, but conventional metallic magnets persist beyond their functional lifetime. Now, a bioresorbable metal-free molecular magnet is developed that can serve as an implanted magnetic signal source, enabling untethered and continuous monitoring of organ motion.
