Abstract Humans can gently slide a finger on the surface of an object and identify it by capturing both static pressure high-frequency vibrations. Although modern robots integrated with flexible sensors precisely detect pressure, shear force, strain, they still perform insufficiently or require multi-sensors to respond physical stimuli during interaction. Here, we report real-time artificial sensory system for high-accuracy texture recognition based single iontronic slip-sensor, propose criterion—spatiotemporal resolution, corelate sensing performance capability. The sensor dynamic (0-400 Hz) high spatial resolution 15 μm in spacing 6 height, together 0.02 Hz at 400 Hz, enabling high-precision discrimination fine features. prosthetic fingertip 20 different commercial textiles 100.0% accuracy fixed sliding rate 98.9% random rates. is expected help achieve subtle tactile sensation robotics prosthetics, further be applied haptic-based virtual reality beyond.
