Scientists Create “Living” Materials That Crawl, Walk, and Dig on Their Own

Researchers from Amsterdam, New South Wales, and Cambridge built rod-and-motor active materials that respond asymmetrically to force.

Unlike ordinary structures that snap once, these lattices can keep buckling and convert that instability into continuous self-propelled motion.

Published in PNAS, the work highlights non-reciprocal interactions and a critical exceptional point in active matter.

The results point to programmable motion in energy-consuming materials, with potential uses in soft robotics and autonomous adaptive systems.
