With their excellent electrical conductivity, extremely high aspect ratio, and flexibility, single-walled carbon nanotubes (SWCNTs) are becoming a core material for robotic electronic skin. They can build sensitive and stable sensor networks that accurately capture multi-dimensional signals like pressure, stretching, and touch. Additionally, they are highly compatible with flexible substrates, meeting the comfort and durability requirements of wearable devices. In the future, SWCNT-based electronic skin will be widely used in cutting-edge fields such as smart healthcare, intelligent robotics, and human-computer interaction, helping industries move toward a more intelligent and user-friendly future.
