A team of researchers from the Iowa State University in Ames, IA has demonstrated a proof-of-concept three-dimensional paper-based microbial fuel cell (MFC) that could take advantage of capillary action to guide the liquids through the MFC system and to eliminate the need for external power. Their report appears in the forthcoming issue of the journal TECHNOLOGY.

The paper-based MFC runs for five days and shows the production of current as a result of biofilm formation on anode.
