Biofuel cell backpacked insect and its application to wireless sensing

This study investigated an enzymatic biofuel cell (BFC) which can be backpacked by cockroaches. The BFC generates electric power from trehalose in insect hemolymph by the trehalase and glucose dehydrogenase (GDH) reaction systems which dehydrogenate β-glucose obtained by hydrolyzing trehalose. First, an insect-mountable BFC (imBFC) was designed and fabricated with a 3D printer. The electrochemical reaction of anode-modified poly-L-lysine,...
