Could tiny magnetic objects, that rapidly clump together and instantly fall apart again, one day perform delicate procedures inside the human body? A new study from researchers at the Max Planck Institute for Intelligent Systems in Stuttgart and at ETH Zurich introduces a wireless method to stiffen and relax small structures using magnetic fields, without wires, pumps, or physical contact.Could tiny magnetic objects, that rapidly clump together and instantly fall apart again, one day perform delicate procedures inside the human body?
