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.
