Stanford engineer aims to connect the world with ant-size radios

Amin Arbabian, an assistant professor of electrical engineering, and his team collaborated with researchers from the University of California-Berkeley, to build a tiny radio 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. Costing just pennies to make, these radios on a chip are designed to serve as controllers or sensors for the 'Internet of Things.'
