Commercial Organic Thin Film Transistors (OTFT) have been characterized to evaluate their variability and reliability. The feasibility of implementing Physical Unclonable Functions (PUFs) based on these devices has been evaluated, taking advantage of the high variation in the electrical characteristics among different OTFTs. The eventual impact of device aging on PUFs reliability has been preliminary explored.
