Magnetic origami robots could transform drug delivery

Researchers have developed a new 3D-printing method to create ultra-thin magnetic films that bring origami-based soft robots to life using external magnetic fields. One robot uses a folding pattern called Miura-Ori, which allows a flat surface to compress into a compact shape and then expand again. This makes it ideal for medical use inside the body, where it can be swallowed in a small form and later unfold to deliver drugs directly to internal ulcers.
