...es into the body, Pushparaj said. The materials required to create the paper batteries are inexpensive, Murugesan said, but the team has not yet developed a way to inexpensively mass produce the devices. The end goal is to print the paper using a roll-to-roll system similar to how newspapers are printed. ...Doernbecher Children's Hospital scientist earns coveted Javits award
