A group of scientists have created a robot made of shape-shifting liquid that they can control to jump, escape cages, and more.
Scientists continue to make intriguing breakthroughs that could help reshape our lives. This time, a group of scientists managed to create a shape-shifting liquid metal that can transition between the solid and liquid state. The new liquid is reminiscent of the liquid shapeshifting seen in 1991’sThe scientists published a paper on the new shape-shifting liquid in the. In it, they discuss how they created the metal and the rigorous tests they put it through.
The scientists utilized magnetic fields to control the shape and movements of the shape-shifting liquid metal robots. The hope is that by using magnets to help move and control the shapeshifting of the robots, the scientists will be able to utilize the liquid metal in both biomedical and engineering technologies, things like targeted drug delivery and circuit assembly.
The key, they explained in the paper, is the use of magnetoactive phase transitional matter . To create that, the researchers used gallium metal embedded with tiny magnetic particles, and then placed the shape-shifting liquid metal robots into magnetic fields that they could control.
As such, being able to shift between solid and liquid allows the metal robot to move fast, but also to take advantage of the strength of a solid object when needed. The ability to move between both states using magnetic fields allowed the robots made of shape-shifting liquid metal to solder circuits, remove objects from a dummy stomach, and even mold themselves into universal screws.
