A research team led by Professor Sung Hoon Kim from the School of Electrical and Computer Engineering at Korea University has developed the world’s first alginate-based microrobot that can be tracked using Magnetic Particle Imaging (MPI). The newly developed system marks a major milestone in microrobotics by enabling real-time localization, selective thermal therapy, and cell delivery—all powered and controlled through a single magnetic actuation system, completely independent of conventional medical imaging devices such as cameras, CT, or X-ray machines.
New placebo-controlled study led by University of Utah engineering professor shows gait retraining eases pain and slows cartilage damage in arthritic knees, raising hopes that relief can be found without drugs or surgery.
