Standford University Engineers Create Ant-Size Radio

The radio is so energy efficient, a university press release states, that it gathers all power necessary from the same electromagnetic waves that carry signals to its receiving antenna. This means the device does not require batteries to operate.

"The next exponential growth in connectivity will be connecting objects together and giving us remote control through the web," said Amin Arbabian, an assistant professor of electrical engineering at Stanford. He recently presented his findings at the VSI Technology and Circuits Symposium.

The project began in 2011, and Arbabian was able to take all the electronics typically found in a Bluetooth device onto a single, ant-sized silicon chip. Based on his designs, the French company STMicroelectronics fabricated working prototypes.

Looking forward, Arbabian hopes to create networks of these chips deployed every meter or so throughout the house. He believes this technology can provide the web of connectivity and control between the Internet and smart household devices. Watch a short video about this high-frequency radio chip below:
