Need Microbatteries? Try 'Smart Ink'

One of the keys to manufacturing miniaturized medical devices, including wearables and implantables, is the miniaturization of batteries. Inching closer to the goal of creating microbatteries, Harvard scientist Jennifer Lewis and her lab have developed 'smart inks' for use in 3-D printers. Based on lithium titanium oxide nanoparticles, the ink can be used to produce a battery's anode and cathode, the components through which current flows. The following video graphically illustrates this new battery-making process.
