A Zinc Ion Capacitor‐Based Fluidic Memristor
Abstract
Abstract The intersection of electrochemistry and neuroscience offers profound insights into ionotronic systems. Here, a zinc‐ion capacitor‐based fluidic memristor (ZIC‐FM) is presented that emulates brain‐like memory functions through nonlinear ion dynamics in electrochemical capacitors. This device functions through voltage‐controlled nonlinear zinc ion plating (under negative bias) and stripping (under positive bias) within its nanoporous carbon electrode architecture, generating hysteretic and history‐dependent resistive switching behavior. It is shown that the ZIC‐FM successfully replicates two key forms of short‐term synaptic plasticity, paired‐pulse facilitation (PPF) and paired‐pulse depression (PPD), closely mimicking biological neural behavior. This work advances the development of fluidic neuromorphic devices that unify energy storage and ionotronic memory, opening new avenues for bio‐inspired computing systems.
