Electronic skin (e-skin) endows robotic hands with tactile, temperature, and force sensing capabilities, and is essential for achieving fine manipulation and natural human–robot interaction. This research involves flexible sensing devices, multimodal perception units, and large-area stretchable interconnect technologies. Our work focuses on multilayer structural design and high-density sensing arrays, enabling dexterous robotic hands not only to detect contact forces, but also to perceive surface texture and material properties.

E-skin systems significantly enhance the flexibility, safety, and intelligence of robotic manipulation, supporting applications such as medical surgery and operations in hazardous environments. However, several challenges remain, including achieving low-latency sensing while maintaining high sensitivity, ensuring mechanical robustness and electrical stability under complex hand motions, and efficiently processing and interpreting large-scale sensory data. This research direction integrates materials science, sensing technology, and artificial intelligence, making it ideal for students interested in advancing intelligent robotics.
