Robot Covered In Living Human Skin
Life imitates art (yes, the Terminator movie is art!) as University of Tokyo roboticists cover a robotic finger with living human skin.
Materials like rubber and silicone don’t move, bend, wrinkle, or even respond to light the same way human skin does, and it’s immediately obvious to our eyes and brains when artificial skin has been used...The most obvious way to cover an artificial being in human skin is to grow sheets of the material in a lab and wrap it around a robot’s various parts, in a similar way to how replacement skin is grown for burn victims. But even with a skilled application, that still leaves seams, something real humans don’t have, and limits how naturally the skin can flex and move if the fit isn’t flawless.
The researchers took an entirely different approach here. A relatively simple robotic finger with three moving joints was first submerged in a solution made up of collagen, a structural protein, and dermal fibroblasts, the primary type of human cells found in skin’s connective tissue and its sub-surface dermis layer. This solution shrank and tightly conformed itself to the robotic finger, creating a flexible foundation on which to apply multiple layers of epidermal keratinocytes, the primary type of human cells found in skin’s outer epidermis layer.

Eventually, I suppose the researchers would create a robot that could repair its own human skin - like the Terminator from the 1984 film.
