Flexible protonic/electronic hybrid rectifying devices gating by chitosan electrolyte were fabricated on polyethylene terephthalate (PET) substrate. indium zinc oxide (IZO) source/drain electrodes with a self-assembled IZO channel were prepared by RF sputtering with a nickel shadow mask. The IZO channel was modified by protonic/electronic coupling and drain current (I D) exhibited rectifying characteristics by short connecting source electrode with bottom indium tin oxide (ITO) film. Such devices were used to mimic inhibitory synapses. Synaptic behaviours, like paired-pulse depression and long-term depression were successfully mimicked in flexible artificial inhibitory synapses. Such inhibitory synaptic devices have potential application for serving as a building brick for future brain-inspired computation systems.
