First, photocrosslinkable small molecule DTFDA was blended with p-type P(g2T-T) and n-type PEG-N2200. Subsequently, vertical architecture OECTs (vOECTs) were fabricated, and their transfer characteristics, transconductance, transient response, and cyclic stability were characterized. Furthermore, OECT-based complementary inverters were constructed, and a dynamic gain regulation system was developed. This system scans the voltage transfer characteristics in real time and adaptively adjusts the input bias to maintain the inverters operating at their maximum gain point, significantly improving the long-term monitoring stability. Finally, ultra-high-density 8×8 vOECT arrays based on cross-point architecture were fabricated using scalable micro/nanofabrication processes, with a device density exceeding 2800 devices/mm². A supporting low-noise multiplexing readout circuit was developed to achieve synchronized data acquisition for 64 channels at a sampling rate of 1 kHz. The dataset covers the entire process of material preparation, device characterization, and system validation, with the data collection period spanning from January 2023 to December 2025. The data were collected using equipment such as semiconductor parameter analyzers, probe stations, optical microscopes, atomic force microscopy (AFM), ultraviolet-visible (UV-vis) spectroscopy, and grazing incidence wide-angle X-ray scattering (GIWAXS). Reliability was ensured through multiple repeated experiments and statistical analyses. Quality control measures include outlier removal, multi-batch sample validation, and long-term cyclic tests (exceeding 200,000 switching cycles). This dataset provides systematic experimental support for high-stability, high-density, and stretchable organic electrochemical transistors and their bioelectronic applications. It is applicable to fields such as wearable health monitoring, neuromorphic computing, and cellular electrophysiological imaging, holding significant scientific research and engineering application value. The total data volume is 2.28 GB.
