Self-healing 'living skin' can make robots more humanlike — and it looks just as creepy as you'd expect

A combination of cultured cells and silicone could help robots appear more human in future thanks to realistic skin elasticity. And they can smile like us too.

Robots of the future could be wrapped in lifelike skin that can repair itself, in a similar way to the way human skin heals, thanks to a novel approach involving cultured skin cells.

The skin will also appear more lifelike thanks to a new way of attaching it to the robot's skeleton as well the fact that it can repair any cuts or scrapes by itself — researchers said. They published their findings June 25 in the journal Cell Reports Physical Science.

Artificial skin has long been touted as a way to make robots appear more human-like — and cultured skin appears more lifelike than synthetic materials such as latex. But without the right kind of adhesive approach, artificial skin can sag off a robot's frame in a visually disturbing manner.

Robotics researchers have previously tried to solve the problem of artificial skin sagging off the metallic frame by pinning it down with "anchors", hooked or mushroom-shaped structures. This prevents the skin from shifting around atop the robot’s frame, but the adhesive structures can stick out as lumps under the skin — compromising its human-like appearance.
