Electronic Devices Could Be Powered by Sugar

Sugar has powered children’s hyperactive lives for centuries—but did you know it may now be able to power your MP3 player, too?

Sugar has powered children’s hyperactive lives for centuries—but did you know it may now be able to power your MP3 player, too?

Japanese scientists from Sony have just produced a new biofuel cell that uses enzymes to convert sugar into energy, which can power small devices like radios, remote-controlled cars, and even your iPod.

Though biofuel cells have been available in the past, they typically aren’t able to produce enough energy to power a device. But the researchers managed to overcome the limitations of previous biofuel cells by increasing the cell’s density with the help of an “electron transfer mediator” and attaching the mediator and enzymes to a carbon-fiber anode, which helps oxygen to flow more efficiently into the fuel cell. By connecting four biofuel cells together, the scientists were able to convert glucose into 100 milliwatts of power.

While it’s not likely that new iPods will come equipped with a slot for a sugar cube battery anytime soon, the research shows promise that renewable resources like glucose can be used for future eco-friendly applications. Plus, this way, it won’t give you cavities.
