In this research, we developed organic bioelectronic i nterfaces based on highly crystalline poly(3,4-ethylenedioxythiophene):poly styrene sulfonate (PEDOT:PSS) films or microfibers to overcome the trade-of f between electrical/electrochemical performance and aqueous stability. Cry stalline PEDOT:PSS films exhibits excellent electrical/electrochemical/opti cal characteristics, long-term aqueous stability without film dissolution/d elamination, and good viability for primarily cultured cardiomyocytes and n eurons over several weeks. Furthermore, they are successfully employed for PEDOT:PSS-based multi-electrode arrays (MEAs) to record and stimulate the a ctivities of primarily cultured cardiomyocytes and chicken retinae tissues. In parallel, we developed crystalline PEDOT:PSS microfibers for single-str and wearable electrochemical transistors, PEDOT:PSS-incorporated hydrogel m icrofibers for 3-D neuronal network reconstruct, and metal oxide transistor arrays for transparent direct cellular interfaces.
