MIT Developing a Battery Half the Size of a Human CellMIT Researchers are working on virus-based microbatteries that are about half the size of a human cell. Using a combination of virus cultivation (which assembles itself) an soft lithography, Paula Hammond and team were able manufacture the battery, which consists of a cathode, anode and electrolyte. They hope the breakthrough will allow for applications like implantable medical sensors and labs that fit on a computer chip. [MIT via Good Clean Tech via PC World]
