Inventing self-healing and living human skin for robots

Japanese scientists succeeded in inventing a kind of self-healing living human skin grown in the laboratory to cover the faces of robots; An achievement that will revolutionize not only the robotics industry but also the field of medicine and treatment.

Even after significant advances in the industry, humanoid robots still do not have an attractive face, and although the newly engineered, laboratory skin of Japanese researchers may not make a robot's appearance any less attractive , but it may one day become a useful medical tool for cosmetic surgeries and other medical procedures.

Engineers at the University of Tokyo have developed a method to glue bioengineered skin grown from human cells onto any surface. In the existing methods, holders and miniature hooks are often used to connect similar tissues to surfaces, which not only limits their application and is easily damaged during movement.

In the Japanese researchers' method for tissue flexibility, miniature V-shaped holes are created in lab-grown skin and then a collagen gel is applied. While the viscosity of the gel usually prevents it from penetrating these small incisions, the engineers used a phenomenon known as steam-based plasma processing, which is commonly used in plastic adhesion processes. This makes the skin more hydrophilic and allows collagen to penetrate the pores and bind the skin to its underlying surface like ligaments.

“By mimicking the ligament structures of human skin and using V-shaped holes created in solid materials, we found a way to connect the skin to complex structures,” said Shoji Takeuichi, who conducted the research and is a professor of mechanics-informatics. . The skin's natural flexibility and strong adhesion method mean the skin can move with the robot's mechanical components without tearing or tearing.”

But even with improved adhesion, this slimy sheen is too ugly and potentially disastrous for lab-engineered skin.

Take Oichi added, “Manipulating soft and wet biological tissues during the development process is much more difficult than lay people think.” For example, if sterility is not maintained, the entry of bacteria can cause tissue death. “But now that it's been successfully done, living skin could bring a whole range of new capabilities to robots.”

To demonstrate this new method, the researchers attached their living skin layers to a 3D model of a human face, as well as to a small 2D “face” with robotic actuators. The skin not only effectively adhered to the rounded features of the human head, but also resisted manipulation using stimuli (plain and smiling faces).

“This soft skin can only partially replicate the human appearance, but this is not the main point of our team's design,” said Take Oichi. Likening this method to the creation of a “body on a chip,” the face-on-a-chip can be expected to provide new avenues for research into skin aging, plastic and reconstructive surgery, as well as cosmetics. “When paired with embedded sensors, a new generation of robots can have better environmental awareness.”

He and his colleagues plan to add the ability to create superficial wrinkles and a thicker epidermis to create a human-like specimen, and they believe that creating thicker and more realistic skin can be achieved by combining sweat glands, sebaceous glands, pores, blood vessels, fat and nerves. brought

The results of this research have been published in Cell Reports Physical Science.
