Development of 3D printable conductive hydrogel with crystallized PEDOT:PSS for neural tissue engineering

Bioelectronic devices enable efficient and effective communication between medical devices and human tissue in order to directly treat patients with various neurological disorders. Due to the mechanical similarity to human tissue, hydrogel-based electronic devices are considered to be promising for biological signal recording and stimulation of living tissues. Here, we report the first three-dimensionally (3D) printable conductive hydrogel that...
