Intelligent, Robust and Biomimetic Textile Sliding Tactile Sensor With Ultrabroad Frequency Perception for Cross‐Domain Object Recognition

ABSTRACT Wireless intelligent tactile perception systems that can replicate human touch are urgently needed for sensory restoration in the dexterous neuroprosthetics and humanoid robots. However, a key challenge, is achieving simultaneous microstructural sensing and large‐area pattern recognition, primarily due to the difficulty in detecting both high‐frequency vibrations and static pressure. Herein, we report a bionic, textile‐based sliding tactile sensor (BTSTS) featuring a Janus 3D honeycomb‐structured sensing electrode paired with an interdigitated electrode. The BTSTS exhibits excellent hydrophobicity, abrasion resistance (withstanding record‐high abrasion 2000 cycles), and exceptional capabilities in perceiving both static pressure and vibrations (5–600 Hz). It represents the first piezoresistive tactile sensor with an ultra‐broad frequency‐detection range surpassing the human vibrotactile limit (<500 Hz). Integrated with a commercial glove, machine learning, and a graphical interface, the BTSTS enables an intelligent, real‐time cross‐domain object recognition system. This system achieves high accuracy (>98.8%) in identifying diverse objects, bridging material innovation with edge‐computing to advance haptic intelligence for human‐robot interaction and sensory augmentation.
