Thanks to top universities and some companies, soft robots and stretchy electronics are already a reality. Now a group of researchers from Purdue claim they've found the right manufacturing process to produce those types of devices en masse. Their method entails printing out circuits using an inkjet printer loaded with liquid metal alloy. "This process... allows us to print flexible and stretchable conductors onto anything, including elastic materials and fabrics," said Rebecca Kramer, one of the researchers. After all, if the circuits are made from liquid metal, they can be stretched, folded, squeezed, and so on and so forth, without breaking.
