Intelligent vision system based on photon-modulated electrochemical doping

An intelligent vision system, comprising:

• a training array of photonic-organic electrochemical transistor (POECT) devices, each device comprising:
• a substrate;
• three terminals including a gate, a drain, and a source disposed over the substrate, wherein space between the drain and the source forms a channel;
• an electrolyte in fluid and electrical communication with the gate and the channel;
• wherein the channel is formed of a photoactive layer composed of donor-acceptor bulk-heterojunction interfaces, each POECT device of the training array provides a memory feature when exposed to light;
• wherein an image to be recognized is imprinted on the training array by exposing the training array with light corresponding with the image to be recognized, and
• a discriminator configured to compare the training array with a test model associated with an image to be tested against the image to be recognized, wherein if the comparison between the test array and the test model provides a match greater than a predetermined threshold, the discriminator signals a match, else the discriminator signals a mismatch.
