Could our bodies themselves act as the sole fuel source for powering medical implants?

A research team, lead by Dr. Serge Cosner, from Joseph Fourier University of Grenoble has created a Biofuel cell technology that receives its power by converting the naturally occurring glucose and oxygen found in the human body into a viable and continuous energy source. The ‘bionic engine’ will make it possible to extend the functional lifetimes of a range of implants and biomedical devices from sensors and drug delivery devices to entire artificial organs. With existing battery technologies, advanced implants like artificial hearts and kidneys can require replacement power sources as often as every few weeks — a process which requires invasive surgery and carries some risk to patients — and demand large amounts of electricity (similar to the heart without a pulse). Dr Cosner’s Biofuel devices could extend the life of implants indefinitely.
