In this paper, we develop wet-spun conductive microfibers based on crystallized Poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (c-PEDOT) which can be fabricated by conventional spinning process. Due to their crystallized molecular structure, microfibers showed high mechanical tensile strength and electrical/electrochemical conductivity, so that it can be appropriate for wearable electronics such as connection wires and fiber-based organic electrochemical transistors (OECTs) for biosensors. Lastly, we can develop OECT-embedded wearable cotton fabrics, and these devices can be stably operated not only in phosphate buffered saline solution, but also on the sweaty human skin over 12 hours. We can expect the c-PEDOT based microfibers can be used for wearable skin electrodes for sensing the biosignals such as EEG, EKG and EMG. |
