#ENERGY: "Self Powered Sensors Eliminate Battery"

All our mobile devices require regular recharging of their batteries, but what if they didn't have batteries because they were self-powered. Columbia University researchers asked that question, then answered it with a new microchip architecture that uses 100-times less power--small enough to be self-powered from light--indoors or out: R.

Columbia University demonstration chip shows that by cutting power 100-times plus communicating only when necessary, ambient light can power battery-free standalone self-powered sensors.
