Fiber-based organic electrochemical transistors for re-shaping bioelectronics: integration on and in textiles

Fiber-based Organic Electrochemical Transistors (F-OECTs) overcome limitations of planar OECTs by enabling mechanical flexibility and textile integration. Their fibrillary conductive structures support stable performance under strain, making them ideal for wearable and biomedical applications. This review highlights recent advancements in F-OECT fabrication, integration strategies, and sensing capabilities, aiming to address the current lack of comprehensive reviews in this emerging field.
