  "abstract": "The integration of sensing, memory, and learning within a single device remains a major challenge for bioinspired electronics. Here, we present an ion‐selective transistor coupled droplet bilayer (TCDB) that combines potassium sensing, ionic memory, synaptic plasticity, and associative learning within a unified iontronic architecture. The platform utilizes a valinomycin‐functionalized droplet interface bilayer that provides selective K+ transport while simultaneously serving as an ionic reservoir that electrochemically gates an organic electrochemical transistor, directly coupling ion transport to adaptive electronic responses, linking ion recognition with information storage and processing. The DIB incorporated OECT exhibits selective potassium sensing together with pronounced hysteretic memory behavior and activity‐dependent conductance modulation characteristic of artificial synapses. Unlike conventional ion‐selective OECT sensors that function solely as transducers, the proposed architecture exploits the intrinsic dynamics of ion transport across a biomimetic membrane to encode and retain information associated with previous ionic events. The resulting device demonstrates the coexistence of sensing, memory retention, and synaptic plasticity within a single platform without requiring separate memory elements or external processing circuitry. This work establishes a new class of adaptive iontronic devices in which sensing and computation emerge from the same ionic processes. The findings open new opportunities for intelligent bioelectronic interfaces, neuromorphic chemical sensors, and membrane‐inspired computing systems.",
