Non-Metallic Squishy Magnets May Soon Power Robots

What do soft robots, medical devices and implants, and next-generation drug delivery methods have in common? Hint: They could all soon be guided with magnetism, thanks to a metal-free magnetic gel developed by researchers at the University of Michigan and the Max Planck Institute for Intelligent.

“If these materials can safely degrade in your body, you don’t have to retrieve them with another surgery later,” said Abdon Pena-Francesch , assistant professor of materials science and engineering affiliated with the Robotics Institute at the University of Michigan and a corresponding author of the study. “This is still pretty exploratory, but these materials could enable newer, cheaper medical operations some day.”
