The groundbreaking innovation of a smiling robot created by Japanese scientists has garnered significant attention on social media. Researchers at Tokyo University have developed a soft and realistic skin made from living human tissue that can be attached to a humanoid robot. This technology is poised to revolutionize the field of robotics by equipping robots with realistic smiles and other facial expressions.
The living tissue used in this experiment was a cultured mix of human skin cells grown in a lab, paving the way for the creation of self-healing skin that is less prone to ripping or tearing. The researchers worked meticulously to recreate ligaments that hold human skin in place using tiny ropes of flexible collagen and elastin. They then drilled small holes into the robot and applied a gel containing collagen before attaching the layer of artificial skin on top, resulting in an elastic product that can move with the mechanical components of the robot without breaking or peeling away.
Prof Shoji Takeuchi, lead researcher on the project, explained that by imitating human skin-ligament structures and using specially made V-shaped perforations in solid materials, they were able to bind skin to complex structures effectively. The natural flexibility of the skin and strong adhesion method ensure that it can move with mechanical components without tearing or peeling away, making it ideal for use in robotic applications.
Although commercial applications are still years away, Prof Takeuchi believes this technology has significant potential applications in various fields such as cosmetics, surgical procedures like plastic surgery, and even skincare research for aging populations. This innovative work opens up new possibilities for future advancements in robotics and skincare science.
In conclusion, this breakthrough has opened up new avenues for robotics research and skincare science by providing robots with realistic smiles and other facial expressions through soft, flexible, and self-healing skin made from living human tissue.
