Abstract

Conducting polymers are promising materials for various applications, but their fabrication has been limited by conventional methods. This paper introduces a high-performance 3D printable conducting polymer ink based on PEDOT:PSS, enabling high-resolution and high-aspect ratio microstructures. The 3D-printed polymers can be integrated with other materials and converted into conductive hydrogels. The authors demonstrate the fabrication of devices such as a soft neural probe for in vivo single-unit recording.
