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.

Implantable memristors are considered an emerging electronic technology that can simulate brain memory function and demonstrate some promising applications in the biomedical field. However, it remains a critical challenge to enhance their long-term stability biocompatibility implantation environments. In this work, implantable memristor has been successfully fabricated based on TiOx using magnetron sputtering. The device demonstrated excellent thermal recoverability at elevated temperatures, providing important experimental evidence for its under high-temperature More importantly, after testing biological mimicking environments, such as fresh pork bullfrog tissues, maintained bipolar resistive switching (RS) characteristics stable performance, indicating potential use medical fields. Further analysis revealed RS behaviors of mainly controlled by space charge limited currents (SCLC), Ohmic conduction, Schottky emission conduction mechanisms. Therefore, is validated real promoting transition from theory practical laying foundation further applications.

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.
