Organic Electrochemical Transistor (OECT) Structure Diagram #1905671 (License: Personal Use)

This schematic illustrates a typical organic electrochemical transistor (OECT) architecture, where a conductive polymer channel (PEDOT:PSS) connects two drain electrodes and is gated via an electrolyte-mediated ionic current. The gate electrode modulates channel conductivity by injecting or depleting ions from the electrolyte into the polymer, enabling low-voltage, high-transconductance operation ideal for biosensing. The overlapping cylindrical geometry emphasizes the volumetric gating mechanism unique to OECTs.
