The technology could make it possible to use radio emissions from cellular networks to wirelessly power sensors and LEDs. Researchers have developed a new metasurface-based antenna, which represents an important step towards practical use of energy harvested from radio waves, such as those used in cellular networks or Bluetooth connections. This technology could potentially wirelessly power sensors, LEDs, and other simple, low-power devices. “By eliminating cable connections and batteries, these antennas could…
