Developed by MIT engineers, Micorbatteris which are about half the size of a human cell and built with viruses could power a range of miniature devices. While the batteries have not yet been built yet, 2 of the 3 main components have already been tested according to an article published in the Academy of Sciences which describes the assembling and testing of the new technology. The researchers used a common technique called soft lithography to create a pattern of tiny posts on a on a clear, rubbery material. On top of these posts, they then deposited several layers of two polymers that together act as the solid electrolyte and battery separator. Next the anode was formed by the a viruses that self-assemble atop the polymer layers on the posts. Creating the batteries does not require any special expensive equipment and can be done at room temperature. No word yet on when these batteries will be available.
