Stanford develops radio the size of ant

We all know that Wi-Fi radio won’t cut it for the billions of things in the IoT.  This radio might.

Engineers from Stanford and Berkeley Universities have figured out how to make radios the size of an ant, which have been created specifically to serve as controllers and sensors in the Internet of Things.

The radios are fitted onto tiny silicon chips, and cost only pennies to make thanks to their diminutive size. They are designed to compute, execute, and relay demands, and they are very energy efficient to the point of being self-sufficient. This is due to the fact that they can harvest power from the incoming electromagnetic signal so they do not require batteries, meaning there is no particular lifetime associated with the devices.

“We’ve rethought designing radio technology from the ground up,” said Amin Arbabian from Stanford, who worked on the project. “The advantage of moving to this architecture is that we can have the scalability we want.” This means that they can scale the technology to potentially thousands of devices within a very dense area.
