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)

Leong Wei Lin, PhD, Nanyang Technological University, Singapore
Dr. Leong received her Bachelor degree in Electrical and Electronic Engineering and Doctor of Philosophy in Materials Science and Engineering from Nanyang Technological University (NTU) in 2004 and 2009 respectively. She performed her postdoctoral fellowship under Nobel Laureate Professor Alan Heeger in University of California, Santa Barbara (UCSB), working on polymer and small molecule solar cells, where she was part of the team to achieve world record efficiency. In 2012, she joined Institute of Materials Research and Engineering (IMRE), working in the area of printed electronics and photovoltaics. In July 2016, she joined the School of Electrical and Electronic Engineering as an Assistant Professor and was promoted to Associate Professor in Sep 2022. Her research focuses primarily on developing organic/hybrid semiconducting devices with features of high flexibility, conformability, printability to enable energy-autonomous systems for digitizing the human body and richer human-robot interaction.
