3D Printed Smart Gel That Walks Underwater

Rutgers University engineers have created a 3D printed smart gel that can grab and move objects and walks underwater. In order to move, the hydrogel is placed in an electrolyte solution with two wires. When electricity is applied, the gel is stimulated to move and change shape. The speed of movement is controlled by the object's thickness and it's shape is determined by the strength of the electrolyte solution and amount of electricity applied.
