Researchers Develop Bio-Hybrid Robot with Living Skin, Capable of Smiling
In a groundbreaking development reminiscent of science fiction, researchers at the University of Tokyo have successfully created a bio-hybrid robot with living, lab-grown skin. This remarkable feat brings us one step closer to the realization of lifelike androids.
The key to this achievement lies in the team's innovative technique for binding living tissue to an inorganic frame, mimicking the structure of human skin ligaments. These ligaments, located beneath the dermis layer, connect the skin to underlying fascia and bone. By replicating this intricate structure, the researchers were able to achieve smooth, realistic facial expressions on the robot.
The process involves drilling V-shaped holes into the robot's surface and applying a solution containing dermal cells to these holes. The skin tissue then gels and hardens, creating a secure bond between the robot body and the cultured skin, similar to the function of human skin ligaments. By manipulating these adhesive ligaments, the researchers were able to induce a smile on the robot's face.
This breakthrough paves the way for further advancements in bio-hybrid robots. The team envisions incorporating sweat glands, pores, blood vessels, and even muscles into the robot's skin to enhance its realism and functionality. They also aim to increase the variety of facial expressions by incorporating a greater number of adhesive holes.
This research, published in the academic journal Cell Reports Physical Science, marks a significant milestone in the field of robotics and brings us closer to a future where human-like androids may become a reality.
