Cleaning Water With Tiny Motors

Motors are an essential component of some of our largest machines, but motors don’t have to be huge to have a big impact. Scientists are developing new motors that are tiny and soft. They run on things like light, magnetic effects or chemical solutions. And they can serve specific functions — including cleaning up pollution.

Watch a demonstration of a new motor designed by a team of Chinese researchers and built from a low-cost hydrogel. The motor is used to clean organic contaminants, such as pesticides, from water. The motor is propelled by oxygen generated from the reaction it uses to clean the water.
