Biofuel cells as a possible power source for implantable electronic devices

A biofuel cell was designed to investigate electricity production from Escherichia coli (E. Coli) and as a preliminary investigation into the possible future use of biofuel cells as power sources for implantable electronic devices. A plexiglass container was fabricated to house the biofuel cell components. Current densities of 24.9 /spl mu/Acm/sup -2/ were obtained, which decreased to 3.58 /spl mu/Acm/sup -2/ over a two hour period.
