Prof. Zhang Yingying at Tsinghua University in Adv. Fiber Mater. (IF 17.2): Nanofiber-Enabled Super Skin for Enhanced Tactile Perception

Challenge: Tactile-enhanced wearables have attracted significant attention for their potential to expand human tactile capabilities and medical rehabilitation applications. However, these devices face challenges including high sensitivity to operational environments (pressure, humidity, touch speed variations) and wearability/comfort concerns.

Approach: Prof. Zhang Yingying at Tsinghua University developed a tactile-enhanced super skin called AtSkin, integrating skin-compatible nanofiber sensor arrays with deep learning algorithms for material recognition unaffected by environmental conditions.

Innovation 1: A lightweight, breathable multilayer nanofiber triboelectric sensor array was fabricated via electrospinning and hot-pressing. Combined with deep learning, AtSkin achieved 97.9% accuracy in distinguishing visually similar resins and fabrics across varying pressures and humidity.

Innovation 2: An intelligent tactile enhancement system was built to identify fabrics with similar textures, demonstrating AtSkin's potential in: 1) Expanding human tactile perception 2) Enhancing augmented reality 3) Revolutionizing smart medical solutions.
