We report an ion-gel-gated amorphous indium gallium zinc oxide (a-IGZO) optoelectronic neuromorphic transistors capable of synaptic emulation in both photoelectric dual modes. The ion-gel dielectric the coplanar-structured transistor, fabricated via ink-jet printing, exhibits excellent double-layer capacitance (>1 μF/cm2) and supports low-voltage operation through lateral gate coupling. integration printing technology enables scalable large-area fabrication, highlighting its industrial feasibility. Electrical stimulation-induced artificial behaviors were successfully demonstrated ion migration gel matrix. Through a simple controllable oxygen vacancy engineering process involving low-temperature oxygen-free growth post-annealing process, sufficient density stable subgap states was generated IGZO, extending responsivity spectrum to visible-red region enabling wavelength-discriminative photoresponses 450/532/638 nm visible light. Notably, exhibited unique interaction dynamics with low-energy photons optically triggered pulse responses. Critical functionalities—including short-term plasticity (STP), long-term (LTP), paired-pulse facilitation (PPF)—were simulated under optical electrical stimulations. device achieves low energy consumption while maintaining compatibility flexible substrates processing (≤150 °C). This study establishes platform for multimodal systems utilizing printed iontronic architectures.

Gel electrolyte-gated organic electrochemical transistors (OECTs) are promising bioelectronic devices known for their high transconductance, low operating voltage, and integration with biological systems. Despite extensive research on the performance of OECTs, a precise model defining dependence OECT gel electrolytes is still lacking. In this work, we refine device to comprehensively account electrical double layer (EDL)’s capacitance electrolyte. Both experimental data theoretical calculations indicate that maximum transconductance contingent upon ion concentration, drain scan rate, highlighting strong correlation between hydrogel Overall, serves as tool improving enabling further development devices.
