MIT engineers have designed an ultrathin fuel cell that converts glucose directly into electricity. They envision the new design could be made into films or coatings and wrapped around medical implants to passively power their electronics using the body’s abundant glucose supply.
Glucose is the sugar we absorb from the foods we eat. It is the fuel that powers every cell in our bodies. Could glucose also power tomorrow’s medical implants?Engineers at MIT and the Technical University of Munich think so. They have designed a new
