Human-like tactile perception is critical for promoting robotic intelligence. However, reproducing tangential “sliding” of human skin still struggling. Inspired by the lateral gating mechanosensing mechanism mechanosensory cells, which perceives mechanical stimuli tension–induced opening-closing ion channels, we report a robot (R-skin) with mechanically gated electron achieving ultrasensitive and fast-response sliding via pyramidal artificial fingerprint-triggered gates (E-gates, namely, customized V-shaped cracks within embedded mesh channels). By imitating cytomembrane to modulate membrane mechanics, local strain enhanced at E-gates effectively regulate pathways high sensitivity while weakened other positions suppress random robust stability. The R-skin can directly recognize ultrafine surface microstructure (5 μm) response frequency (485 Hz) outshining humans achieve human-like functions, including dexterously distinguishing texture complex-shaped objects providing real-time feedback grasping.
