“Costing just pennies to make, tiny radios-on-a-chip are designed to serve as controllers or sensors for the ‘Internet of Things.’
[youtube https://www.youtube.com/watch?v=i5bnmRpJmXA]A Stanford engineering team, in collaboration with researchers from the University of California, Berkeley, 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.””
