Scientists from the University of Tokyo have successfully attached engineered living skin tissue to humanoid robots, paving the way for a future where robots could have self-repairing, synthetic skin for a more lifelike appearance. The study led by professor Shoji Takeuchi involved making tiny v-shaped perforations in the robot's faceplate material, allowing the skin to be attached using collagen gel and plasma treatment. The researchers tested their method on a 3D humanoid robot face and a moving version, both of which were slightly nightmarish in appearance. The goal is to eventually create synthetic skin with structural elements like pores, glands, fat, and nerves to achieve a more realistic human appearance. This breakthrough could have implications for various fields, from surgical procedures to cosmetics. The researchers aim to improve the robots' movements and expressions by integrating more sophisticated actuators in the future.
