Japanese scientists have found a way to attach living skin to robot faces, for more realistic smiles and other facial expressions. <\/p>\n

The breakthrough came from copying tissue structures in people, according to the team at Tokyo University. <\/p>\n

The prototype may appear more Haribo than human-like.<\/p>\n

But the researchers say it paves the way to making convincingly realistic, moving humanoids with self-healing skin that will not easily rip or tear. <\/p>\n<\/div>\n

Scientists say their new method can work on complex, curved and even moving surfaces<\/figcaption><\/p>\n<\/figure>\n

The artificial skin is made in the lab, using living cells.<\/p>\n

Not only is it soft, like real skin but it can repair itself if cut, the scientists say. <\/p>\n

Past attempts to attach it proved difficult, though. <\/p>\n

The team tried using mini hooks as anchors – but those damaged the skin as the robot moved. <\/p>\n

In people, the skin is tethered to underlying structures by ligaments – tiny ropes of flexible collagen and elastane. <\/p>\n

To recreate that, the researchers drilled lots of little holes into the robot and applied a gel containing collagen, and then the layer of artificial skin on top. <\/p>\n

The gel plugs the holes and tethers the skin to the robot.<\/p>\n<\/div>\n

“By mimicking human skin-ligament structures and by using specially made V-shaped perforations in solid materials, we found a way to bind skin to complex structures,” lead researcher Prof Shoji Takeuchi said.<\/p>\n

“The natural flexibility of the skin and the strong method of adhesion mean the skin can move with the mechanical components of the robot, without tearing or peeling away.”<\/p>\n

The latest results are published in the journal Cell Reports Physical Science<\/a>. <\/p>\n

It will take many more years of testing for the technology to become an everyday reality, the researchers say.<\/p>\n

“Another important challenge is creating human-like expressions by integrating sophisticated actuators, or muscles, inside the robot,” Prof Takeuchi said. <\/p>\n

But the work may also be useful in research into skin ageing, cosmetics and surgical procedures, including plastic surgery.<\/p>\n<\/div>\n<\/div>\n
