Abstract Organic memristors have emerged as promising candidates for neuromorphic computing due to their potential low‐cost fabrication, large‐scale integration, and biomimetic functionality. However, practical applications are often hindered by limited thermal stability device‐to‐device variability. Here, an organic polymer‐based memristor using a thiadiazolobenzotriazole (TBZ) 2,5‐Dioctyl‐3,6‐di(thiophen‐2‐yl)pyrrolo[3,4‐c]pyrrole‐1,4(2H,5H)‐dione (DPP)‐based conjugated polymer is presented that exhibits exceptional reliable resistance switching behavior over wide temperature range (153–573 K). The device leverages charge‐transfer mechanism achieve gradual uniform switching, overcoming the challenges associated with filamentary‐based mechanisms. memristor's consistent performance enable its integration into various applications, including image processing. device's ability demonstrated effectively deblur images, even under varying conditions, showcasing robust computing. This study establishes pathway toward high‐performance, thermally stable advanced artificial intelligence applications.

Abstract Dynamic detection is crucial for intelligent vision systems, enabling applications like autonomous vehicles and advanced surveillance. Event‐based sensors, which convert illumination variations into sparse event spikes, are highly effective dynamic with low data redundancy. However, current event‐based sensors simplified photosensitive capacitor structures face limitations, particularly in their spectral response, hinders information acquisition multispectral scenes. Here, we introduce a two‐terminal thin‐film sensor that innovatively integrates an inorganic oxide p–n junction the pyro‐phototronic effect, synergistically combining photovoltaic pyroelectric mechanisms. This innovation enables spiking signals tenfold increase responsivity, range of 110 dB, extended response from ultraviolet (UV) to near‐infrared (NIR). With array, these accurately extract fingerprint edge features even under low‐light conditions, benefiting high sensitivity minor luminance variations. Additionally, sensors' broadband captures richer information, achieving 99.25% accuracy gesture recognition while reducing processing by over 65%. approach effectively eliminates redundant minimizing loss, offering promising alternative perception technologies. image

Abstract Flexible resistive random‐access memory (RRAM) holds significant promise for data storage applications in the realms of smart healthcare and wearable devices. However, most research has focused primarily on development stretchable electrodes, frequently neglecting mechanical compatibility between functional layer electrode.

Herein, glassy metal‐organic framework (MOF) film with wrinkle structure is integrated pre‐stretched electrode to fabricate memristors. These devices demonstrate an impressive switching ratio up 10 5 , bending radius limit mm, strain 20%, all while maintaining stable characteristics. Furthermore, conductive atomic force microscope (C‐AFM) ion beam (FIB) techniques reveal that effect governed by silver filament mechanism. This work successfully developed memristor, paving way application MOFs as layers flexible electronics. It expected inspire further design high‐performance, electronic technologies.
