  Why isn't this widely available yet? There's a few chips that can do battery free Bluetooth, but I haven't seen any commerical products.

    This one is baterry-powered, and the article says power is the difficult part.

      It also says: > 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...

    > 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.

      I wonder how easily they can be "sniffed" out and found.

  An interesting take on similar technology is Vernor Vinge's _A Deepness in the Sky_. https://en.m.wikipedia.org/wiki/A_Deepness_in_the_Sky#Localizers https://en.m.wikipedia.org/wiki/A_Deepness_in_the_Sky#Locali...
