Tokyo Scientists discovered "walking gel"

Scientists from Tokyo University discoveres a new material, that can "walk like a inchworm". As you can see in this video, it's very small - and very revolutionary, because the material can move, without electrical power. It's coming all from a chemical reaction inside the material.

Shingo Maeda and colleagues made the colour-changing, motile gel by combining polymers that change in size depending on their chemical environment. This is based on an oscillating chemical reaction called the Belousov–Zhabotinsky (BZ) reaction. The result is an autonomous material that moves without electronic stimulation.

In short, the concentration of one or more compounds in the gel periodically increases and decreases, resulting in this "walking pattern". Discovered by the Shuji Hashimoto applied physics laboratory the Waseda University in Tokyo.
