Researchers at the University of Tokyo have made significant strides in the realm of robotic technology with their latest breakthrough in artificial skin development. Drawing inspiration from human ligament structures, the team has pioneered the use of perforation anchors to attach living skin efficiently onto robotic surfaces, enhancing facial expressions and interactions with humans.
The experimental living skin, cultivated in a lab setting, mimics the biological characteristics of human skin with its self-repairing abilities and soft, flexible nature. The application of this innovative skin onto robots results in more realistic facial expressions, ultimately boosting the naturalness and effectiveness of human-robot interactions.
Innovating the process of skin attachment, researchers have devised perforation anchors primarily composed of collagen and elastin, reminiscent of human ligaments crucial for anchoring skin to underlying tissues. Although the prototype may resemble more of a gummy candy than a human face, it paves the way for the creation of humanoid robots with self-healing skin.
Described in the journal Cell Reports Physical Science, the new method excels in adhering artificial skin to complex, curved, and even moving surfaces. By perforating small holes on the robot’s surface and applying a collagen gel followed by a layer of artificial skin, the gel fills the holes and secures the skin onto the robot, mimicking the structure of human ligaments.
Lead researcher Prof. Shoji Takeuchi explained, “By mimicking the structures of human skin ligaments and utilizing specially designed V-shaped perforations, we have found a way to connect skin to complex structures.” Various experiments, such as plasma treatment to enhance collagen penetration and tension tests to assess anchor effectiveness, have demonstrated the efficiency and strength of the perforation anchors in robotic skin development.
