This cute pink blob could lead to realistic robot skin

Someday, we may have humanoid robots so real, they have skin that looks and feels, heals and moves just like ours. A team of scientists from the University of Tokyo and Harvard University are looking into how to make that happen, and the process includes creating some pretty curious, partly terrifying and partly adorable experimental machines with skin. In their paper published in Cell Reports Physical Science (via TechCrunch), the researchers explained that current molding techniques used to create skin equivalents that can fit 3D structures like robotic fingers perfectly do not have a mechanism that can "fix the skin to the underlying subcutaneous layer." For their study, they used a technique they're calling "perforation-type anchors," which is inspired by skin ligaments, as a solution to that problem. Simply put, skin ligaments keep our skin attached to the tissue and muscle underneath, so it doesn't get loose and go all over the place like fabric on a mannequin whenever we move.
