There has been considerable recent interest in wearable biofuel cells based on printing technologies.1 Screen-printing technique has following merits; drawing precise pattern of um order, a wide variety of inks, high reproducibility, and low cost. Thus, screen-printing has been widely used for fabrication of electrochemical devices such as dye-sensitized solar cells, biosensors and corrosion sensor. 2-5

 Recently, we prepared a screen-printed paper-based biofuel cell using porous carbon inks and showed its high output power. 6 In the present study, we newly demonstrated a screen-printed paper-based biofuel cell which consisted of lactose oxidase-modified and billirubin oxidase-modified porous carbon electrode fabricated on the paper substrate. Firstly, the characteristics of the bioanode and biocathode were investigated independently by the three-electrode method; the bioanode or biocathode was connected to a potentiostat. A Ag|AgCl reference electrode and Pt wire counter electrode were placed in the electrolyte solution. Then, electrochemical response of the BFC was examined.
