Researchers at the University of Michigan have unveiled their latest breakthrough: A tiny solar power system that contains a processor, battery, and solar cells all in 9 cubic millimeters!


The miniature system measures 2.5 by 3.5 by 1 millimeters - 1,000 times smaller than any comparable commercial system. It's extremely energy efficient and the scientists say that it could almost operate perpetually if the battery didn't have to be replaced after many years.

The first thing that comes to mind for me is the monitoring of aging monuments without distracting from their artistic beauty, like the Golden Gate Bridge or others that require maintenance.
