Butterfly-inspired ceramic microscrolls unroll with magnets to power tiny robots

Researchers at the University of Stuttgart and the Max Planck Institute for Solid State Research have developed tiny rolls that can be unrolled and rolled up in a controlled manner using a magnet. The model for this was the proboscis of butterflies. These smart materials enable the development of more efficient drive technologies for micro- and soft robotics, a field of research of great economic importance. The results have been published in the journal Advanced Materials.
