I know this isn't security related, but it is too cool for words: On viewing the latest winners summaries from this years IDTechEx awards, I came across this little blurb about Jennifer Lewis and her team at Harvard:
“{they have} printed rechargeable 3D Li-ion microbatteries composed of high–aspect ratio anode and cathode micro-arrays that are interdigitated on a sub-millimeter scale, and exhibit amongst the highest area energy and power densities reported to date. These microbatteries occupy volumes less than 1 mm3—equivalent in size to a single grain of sand—and are 1000 times smaller than the smallest commercially available rechargeable batteries. The university is working on developing these batteries for a broad range of autonomous applications, including biomedical devices, micro-UAVs, and distributed sensor arrays (e.g., smart dust).”

A good summary of the procedure can be found here:
