논문초록 Herein, we report conducting polymer microfiber-based organic electrochemical transistors (OECTs) and their application to single strand fiber-type wearable ion concentration sensors. We developed the simple wet-spinning process to form very conductive poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) microfibers, while their electrical/electrochemical properties were carefully examined. In conjunction with fabricating substrate-free PEDOT:PSS microfiber-based OECT devices, the proposed novel characterization method proved that the current variation ratio can be a reliable method to evaluate their performance of sensing ion concentrations, regardless of actual channel dimensions. Finally, we developed single strand fiber-type skin-mountable OECTs by introducing the source-gate hybrid electrode, and demonstrated that the resultant microfiber sensors can perform real-time repetitive measurements of ion concentrations in human sweat.
