Organic Electrochemical Transistors

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.
This collection welcomes the following topics, including but not limited to:
- New materials and structures for OECT
- New fabrication methods or techniques for flexible OECTs
- New operation modes and applications of OECT
- The demonstrations of OECT applications combined with other technologies (for example, transient electronics, self-powered systems, self-healing electronics)

The Collection will publish original research papers, and articles in various formats (full details on content types can be found here). Papers will be published in npj Flexible Electronics as soon as they are accepted and then collected together and promoted on the Collection homepage. All Collections are associated with a call for papers and are managed by one or more journal editors and/or Guest Editors.
This Collection welcomes submissions from all authors – and not by invitation only – on the condition that the manuscripts fall within the scope of the Collection and of npj Flexible Electronics more generally. All submissions are subject to the same peer review process and editorial standards as regular npj Flexible Electronics articles, including the journal’s policy on competing interests. The Editors declare no competing interests with the submissions which they have handled through the peer review process. The peer review of any submissions for which the Editors have competing interests is handled by another Editor who has no competing interests. For more information, refer to our Collections guidelines.
This Collection is not supported by sponsorship.
