Scientists Grow Self-Healing Skin for Robots
wear and tear: the damage that happens to something from normal use over time
Scientists in Japan are now growing skin for robots, bringing them one step closer to humans. This skin is made from cells that grow in a lab. The researchers found a way to attach this skin to robots without it falling off. The skin looks and moves just like human skin. In one test, they made a robot smile. If the robot gets a small tear, the skin can heal itself. Live Science reports that the skin will be able to prevent “undue wear and tear,” helping the robot last longer without needing repairs. Scientists plan to add temperature and touch sensitivity and improve the skin’s strength to match natural human skin.
