Researchers have developed a new metasurface-based antenna, which represents an important step in making it convenient to collect energy from radio waves, such as those in cellular networks or Bluetooth connections. This technology could potentially offer wireless power to sensors, LEDs and other simple devices with low power requirements. “By eliminating cable connections and batteries,
The demand for flexible and inexpensive wireless communications and applications has sparked interest in innovation in wireless energy collection. For example, scientists were able to use organic material for a new semiconductor design for radio frequency circuits. Notably, organic semiconductors have applicability in 5G applications, according to international scientists led by King Abdullah University of
