University of Tokyo grows living human skin on a robotic finger that self-heals in a week
bennash · x · 2026-10-05
Researchers at the University of Tokyo grew skin from human cells directly on a working robotic finger. The cells formed layered structures resembling real skin — dermis and epidermis — stretched and bent with the robot's movement, and even developed natural wrinkles at the joints. Notably, when cut, the living skin repaired itself in about a week with a collagen bandage. Durability remains the key challenge; the work targets lifelike humanoid robots and skin research.
