Key Points

To develop an optically modulated artificial ionic synapse using a photoresponsive nanofluidic Janus membrane capable of neuromorphic processing and ionotronic logic operations.
Synthesized a Janus membrane with asymmetric ion-selective nanochannels by incorporating photo-responsive spiropyran groups onto a poly(aryl ether sulfone) backbone.
Integrated the membrane into multi-device circuit architectures to measure optical and electrical signal responses and evaluate diode-based synaptic behavior.
Established stable optical control over nanochannel charge density and achieved ionic diode behavior with tunable ionic rectification.
Successfully emulated biological short-term plasticity mechanisms, including paired-pulse facilitation and spike rate-dependent plasticity.
Achieved reconfigurable logic outputs through the coordinated processing of optical and electrical inputs in multi-synapse circuits.
