Glucose biofuel cells are promising candidates to supply implanted electronic devices by converting the chemical energy of glucose, present in body fluids, into electric power. Before such biofuel cells can become realistic alternatives compared to presently used lithium batteries, several obstacles still have to be overcome such as life time and effective power output. These issues are discussed and some breakthroughs of the research team in Grenoble are presented. For instance, a special design of a glucose biofuel cell combined with an adapted surgical intervention technique enabled to light a digital thermometer and a LED out of the body liquid of a freely moving rat with one single biofuel cell. Further designs and alternative approaches will be discussed.
