Organic electrochemical transistors (OECTs) are an emerging class of transistors based on organic superconducting materials known for their ability to modulate electrical current in response to small changes in the voltage applied to their gate electrode. Like other electronics based on organic semiconductors, these transistors could be promising for the development of various brain-inspired and wearable technologies.
OECTs have various notable advantages, including promising amplification and sensing capabilities. low driving voltages, and a versatile structure. Despite these advantages, most conventional OECTs developed so far have been found to exhibit various limitations, including limited stability and slow redox processes, which can significantly impair their performance.
Researchers at Northwestern University recently outlined a new strategy to fabricate high-density and mechanically flexible OECTs. Their proposed approach, outlined in a paper in Nature Electronics, was used to create various electronic components based on OECT arrays and circuits.
"Organic electrochemical transistors (OECTs) can be used to create biosensors, wearable devices, and neuromorphic systems," Jaehyun Kim, Robert M. Pankow, and their colleagues wrote in their paper.
