Tiny wireless using power harvesting


#1

[quote]A Stanford Univ. engineering team has built a radio the size of an ant, a device so energy efficient that it gathers all the power it needs from the same electromagnetic waves that carry signals to its receiving antenna—no batteries required.

Designed to compute, execute and relay commands, this tiny wireless chip costs pennies to fabricate, making it cheap enough to become the missing link between the Internet as we know it and the linked-together smart gadgets envisioned in the “Internet of Things.”

That is very neat!

Similar to this thing that uses an Arm m3 MCU

Pretty cool - and tiny. Interesting how they stacked the components.

@ mhectorgato - that M3 MCU is only running at about 32khz or something though so it’s no powerhouse. Netmf will never run on it. If you look at some of their publications you will see just how deep they have gone down deep into the silicon to save microwatts.
