Physicists studying active matter — materials that can use their own internal energy to respond to forces — have uncovered surprising behaviors that challenge conventional ideas in mechanics. Materials that bend, snap, crawl, or even dig on their own may sound like science fiction, but physicists are now building systems that can do exactly that. [...]
Most materials we use every day—like metal, glass, or rubber—are passive. They only move or change shape when we push or pull them. But scientists are now exploring a very different kind of material, called “active matter,” that can move and respond using its own energy. These materials don’t just bend under pressure—they can snap, […] The post Scientists create materials that can walk, crawl, an…
