In a Japanese robotics lab at Waseda University, Tokyo, Shuji Hashimoto has created a chemical gel that can walk like an inchworm.
“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.”
