Battery-Free Power in Ant-Sized Chip

As technology continues to shrink and automate the world around us, two major challenges are inescapable: finding a sufficient power source, and procuring the aforementioned power source at a reasonable cost.

Recently, Arbabian, an assistant professor of electrical engineering at Stanford University, developed a battery-free chip the size of ant that he maintains will cost only a few cents to make. The device is so energy efficient that it gathers power from the electromagnetic waves that carry signals to its receiving antenna, allowing it to power itself as it operates.
