Innovators led by W. Zeng have engineered a magnetic soft millirobot that integrates simultaneous locomotion and environmental sensing capabilities. Constructed from a flexible polymer matrix embedded with magnetic nanoparticles, the robot achieves complex wave-like motions controlled wirelessly by magnetic fields. Flexible sensors woven into its body continuously detect parameters such as pressure, temperature, and chemicals, transmitting real-time data during movement. Published in npj Flexible Electronics, this development promises applications ranging from precise medical diagnostics and drug delivery to responsive environmental monitoring.
