Abstract With the development of modern medicine, importance continuous and reliable pulse wave monitoring has increased significantly in physiological evaluation disease diagnosis. Among them, 3D reconstruction is indispensable, needs rely on ultra‐high resolution sensor arrays, that is, high spatial resolution, temporal force resolution. Herein, a flexible high‐density 32 × tactile array based pressure‐sensitive tunneling mechanism develpoed. Conformal graphene nanowalls ( GNWs ) pattern arrays are deposited micro‐pyramidal structural Si substrate via mask‐assisted plasma enhanced chemical vapor deposition PECVD) method adopted as electrode, exhibiting 64 dots/cm 2 , sensitivity (222.36 kPa −1 short response time (2 ms). More importantly, HfO layer can effectively suppress noise current, which made it sense weak pressure signals with 1/1000 SNR 36.32 dB. By leveraging its high‐resolution array, more holistic acquired shape successfully replicated. This work shows sensors have significant promise for applications remote intelligent diagnostics.

Converting external physical information into tactile sensations for efficient dynamic processing like human beings is crucial edge applications such as intelligent prosthetics and robotics. Reservoir computing, a bio-inspired computing paradigm, excels at temporal signals offers advantages low training costs easy deployment on devices. Many have been developed reservoir using However, there has paucity of research to simulate the system. Furthermore, implementation reusable system significant importance. Herein, we implement near-sensor haptic simulation, utilizing simple peripheral circuit design. The reservoir's high-dimensional, nonlinear, short-term memory requirements are physically realized by memristor with an integrated lithium polymer electrolyte polycrystalline tungsten oxide layer, which exhibits good cycle-to-cycle consistency. As proof concept, completes learning classification tasks Braille numerals characters, achieving high recognition accuracy up 96% within 400 cycles. This approach innovative insights developing human–machine interaction enhanced perception capability.

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.
