Materials: Japanese scientists announcing to have discovered a walking gel

Eggshell Robotics reports that Japanese scientists announced to have discovered a new material, a color-changing motile gel. According to these scientists from Tokyo University, this material can "walk like a inchworm".


This is a very small material, announced to be revolutionary. Moreover this material can move without electrical power. This motile gel has been obtained by combining polymers capable of changing in size depending on their chemical environment.

This strategy is based on an oscillating chemical reaction called the Belousov-Zhabotinsky (BZ) reaction explaining why this material can move without electronic stimulation.
