And on the menu at the Italian Institute of Technology (IIT), an entirely edible battery. Researchers in Milan have developed the rechargeable prototype out of common-place food stuffs with the hopes of revolutionising ingestible medical devices.
"The core of the device is represented by a couple of electrodes... To have it working we are using two materials, two molecules. For the anode, we are using riboflavin which is a vitamin we can find in almonds... and for the Cathode we are using quercetin. It’s sold as a food supplement and can be found in capers,” explained Mario Caironi, the coordinator of the project.
