a Schematic illustration of the printing process on porcine tissue. b 3D scan and reconstruction of the curved surface of porcine tissue. c Design of the 3D spiral printing path on the reconstructed surface. The color represents the height magnitude. d Photographs of the minimally invasive bioprinting process of a conducting hydrogel on porcine tissue at various times.
