Some day, all our homes and office buildings will turn off the lights when we’re not around, make sure the coffee pot’s off, adjust our thermostats for maximum comfort and energy savings, and generally be the responsible energy users we have failed to be. It’s the promise of the smart grid.

That’s where ultra-low-power devices and energy harvesting come in.
