Herein, novel lead-free Cs3Bi2I9 nanocrystals (NCs) were preferred through first-principles calculations and crystal orbital Hamilton population (COHP). An artificial nociceptor was designed using the halide perovskite (HP) NCs doped into poly(methyl methacrylate) (PMMA). The resulting composite material memristor demonstrated remarkable resistive switching performance conductive atomic force microscopy (C-AFM). PMMA&Cs3Bi2I9-based memristors show an ultrafast speed of 30 ns low threshold voltage ≈0.6 V with little variation, which attributed to synergistic effect active metal electrodes vacancy filaments. Impressively, high mechanical bending stability (bending times = 1000) still exhibit excellent resistance state (RS) properties multilevel storage after days exposed ambient conditions. More importantly, fundamental nociceptive functions fully demonstrated. Furthermore, a mechano-nociceptor system simulate mechanism biological pain perception, could selectively react mild harmful stimuli. Our study provides new strategies for developing efficient neuromorphic materials devices.
