The Shape Shifting Robotic Micro Swarm

The shape shifting robotic micro swarm is an army of teny tiny robots that have the powr to brush teeth and teeth at all, hands free and automatically. The researchers use something called iron oxide nano particles which can be shaped into anything from a bristle to a floss. A magnetic field is the area of a magnet that has magnetic force. And in this case, those larger materials are a shape shifting bunch of bristles, brushes and even long strands of plarks.
