> With the M3, engineers at Michigan are the first to accomplish energy neutrality via indoor energy harvesting in a wireless system of its size. With a 1mm2 solar cell producing 20nW, the device can harvest enough energy under ambient light to run perpetually.
One key application for this line of smart sensors lies in personal security and information. Numerous specks of technology could be discretely placed to invisibly monitor a home, business, or personal device.
Do most people really want more pervasive surveillance?

I wonder how sensitive these are to EMP...
Potentially "not very". Their small size means you would need higher electric field to get decent voltage difference across the device.
[UPDATE] Now it is back!
