A new form of locomotion has been discovered, and it is powered by nothing but electricity. Scientists have developed a hydrogel that can move in response to electric fields. This groundbreaking discovery could open up a world of possibilities when it comes to robotics and soft-bodied micro-machines. The hydrogel is able to move without the need for motors or other complex machinery. This could lead to more efficient and cost-effective ways of moving objects in the future. The hydrogel is an exciting new development that may revolutionize the way we think about locomotion.
