Microbatteries

A collaboration between engineers at the University of Illinois-Urbana-Champaign and Harvard’s Wyss Institute for Biologically Inspired Engineering have, first, invented an ink of nanoparticles and then used 3-D printing to deposit tight stacks of anodes and cathodes on a gold structure in making microbatteries that are the size of a grain of sand.  Once the microbatteries are formed they are placed in a small container and filled with an electrolyte solution.  Among many things, these microbatteries could be used in many kinds of wearable, ingestible and implantable medical devices.
