The invention relates to a three-terminal artificial
synaptic device based on a digital controllable printing ITO (
Indium Tin Oxide)
nanowire and a preparation method of the three-terminal artificial
synaptic device. According to the device, a
nanowire array is distributed on a substrate, a source
electrode and a drain
electrode are distributed at the two ends of the array respectively, and ionic glue is arranged between the source
electrode and the drain electrode to serve as a grid electrode; the preparation method comprises the following steps: firstly, preparing an ITO
nanowire by using an electrofluid printer, and taking the ITO nanowire as a channel material of the
synaptic device; then
metal electrodes are evaporated on the ITO nanowire subjected to high-temperature annealing to serve as a source electrode and a drain electrode, and finally the three-terminal artificial
synapse device is manufactured by using ionic gel as a grid electrode. The method is simple in process, easy and convenient to operate, low in cost, energy-saving, environment-friendly and suitable for large-scale production, and provides beneficial guidance for
material selection and device design in the field of neuromorphic calculation.
