For example, these existing manufacturing techniques for conducting polymers are limited to low-resolution (e.g., over 100 µm), two-dimensional (e.g., low aspect ratio) patterns, and/or complex and high cost procedures (e.g., multi-step processes in clean room involving alignments, masks, etchings, post-assemblies) 4, 5, 7, 14, 15, 16 (Supplementary Table 1), which have hampered rapid innovations and broad applications of conducting polymers. Despite recent advances in conducting polymers and their applications, the fabrication of conducting polymer structures and devices have mostly relied on conventional manufacturing techniques such as ink-jet printing 4, 5, 6, screen printing 7, aerosol printing 8, 9, 10, electrochemical patterning 11, 12, 13, and lithography 14, 15, 16 with limitations and challenges. We further demonstrate fast and streamlined fabrications of various conducting polymer devices, such as a soft neural probe capable of in vivo single-unit recording.Ĭonducting polymers, a class of polymers with intrinsic electrical conductivity, have been one of the most promising materials in applications as diverse as energy storage 1, flexible electronics 2, and bioelectronics 3, owing to their unique polymeric nature as well as favorable electrical and mechanical properties, stability, and biocompatibility. ![]() ![]() The 3D-printed conducting polymers can also be converted into highly conductive and soft hydrogel microstructures. The resultant superior printability enables facile fabrication of conducting polymers into high resolution and high aspect ratio microstructures, which can be integrated with other materials such as insulating elastomers via multi-material 3D printing. Here we introduce a high-performance 3D printable conducting polymer ink based on poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) for 3D printing of conducting polymers. However, the fabrication of conducting polymers has mostly relied on conventional approaches such as ink-jet printing, screen printing, and electron-beam lithography, whose limitations have hampered rapid innovations and broad applications of conducting polymers. Conducting polymers are promising material candidates in diverse applications including energy storage, flexible electronics, and bioelectronics. ![]()
