Researchers have developed a breakthrough method using cultured skin cells and silicone to create lifelike, self-repairing skin for robots. This innovation aims to enhance robots’ appearance and functionality by mimicking human skin elasticity and ability to heal.
Artificial skin has long been pursued to humanize robots, but previous attempts often resulted in unnatural appearances or issues with durability. In this new approach, researchers employ a unique adhesive method involving tiny holes in the robot’s skeleton, allowing the cultured skin to attach seamlessly using “perforation-type anchors.” This keeps the skin smooth and flexible, preventing sagging or detachment.
The artificial skin is treated to be hydrophilic, ensuring better adhesion and allowing it to heal cuts or scrapes autonomously. Additionally, it mimics human facial expressions by integrating a sliding silicone layer beneath the skin, which moves like muscles to simulate actions such as smiling.
Future advancements aim to improve skin durability and strength, potentially integrating sensory capabilities like temperature and touch. This research not only enhances robotic aesthetics but also holds promise for medical applications, such as facial paralysis treatment and advancements in cosmetic and orthopedic surgeries.
