An Organic Electrochemical Transistor (OECT) is an organic electronic device that comprises a conjugated polymer channel in direct contact with an electrolyte. The current flowing through the device is controlled by the injection of ions from the electrolyte into the conjugated polymer. The flow of ions is driven by a voltage applied to the gate electrode, which is in contact with the channel through the electrolyte. The migration of ions between the channel and the electrolyte changes the conductivity of the channel in a process called electrochemical (or bulk) doping, switching the transistor between ON and OFF states. The unique features of OECTs include low voltage operation, biocompatibility, operational stability in aqueous electrolytes, and the ability to convert small ionic signals into very large electronic signals (iontronic amplifiers), thus providing a transducer choice for next-generation wearable, in vitro, and implantable bioelectronic devices. Recent research has shown that OECT-based biosensors are capable of sensing neural activity, monitoring cells, detecting proteins, nucleic acids, and metabolites. They can also be used as multi-bit memory devices that mimic the synaptic functionalities of the brain. For this reason, OECTs are also being investigated as elements in neuromorphic computing applications and artificial neurons.
