edit: wifi router could power these sensors, just a limited range.
"we simulate an ASIC, which achieves 60 fps 720p and 1080p HD video streaming for 321 µW and 806 µW, respectively" simulate, how convenient!
"Our inter and intra-frame compression algorithms reduces total bandwidth requirements by up to two orders of magnitude compared to raw video" so they also invented mpeg4 level of compression 1mW codec.
You might wonder how such an amazing compression codec works? its middle-out. They transmit "fullhd" by transmitting ~100x50 resolution intra frames ":). Everything is Simulated, Estimated, Planned, Theorized, Calculated and Faked. That cool 1080 YT clip of them walking around the corridor just after showing you face mounted camera models? Never happened, prototype is BW 112×112, "simulated" again. Their setup can do 1080@60 of a static picture, there is only enough bandwidth to sustain ~2fps without dropping data. They even conveniently kept all the calculations ignoring color (3x the data).
Reminds me of energy harvesting wristwatch crowdfunding HN was raving about few months back, conveniently ignoring particular design including battery able to power it for couple of years.
try 10-20 days if you believe in their simulated 800uW ASIC with magic middle out compression. Assuming everything works according to their predictions and simulations (nothing was actually build to confirm that) you have to pump 1W from your cellphone to power 1mW wearable camera. Your cellphone will run out of battery after 4-6 hours.
Think about that for a second, they want you to recharge your phone every 6 hours to "save from inconvenience of recharging your wearable". This is they main proposed design, right there in YT presentation.
