| 논문초록 | Organic electrochemical transistors (OECTs) have been recently developed in biosensor applications including physiological signal monitoring, ion concentration sensing, due to their unique operation mechanism based on electrolyte ions-assisted redox reaction in active materials. Furthermore, the pressing needs for versatile applications such as portable, implantable biosensors demand the scale-down of biosensors; however, the miniaturized device size districts the device performance, that is low sensitivity, increased noise level, and inefficient ion exchange. In this study, we demonstrate the microfiber-built OECT for reading the concentration of diverse ions, in which channel is vertically aligned for enhancing transmittance as well as endurance to horizontal mechanical stresses. We expect that this novel device architecture on microfiber will pave the way for low-dimension multi-functional biosensors via employing various functional fibers. |
