Antenna-Based Power Generation with Nanoscale Rectifying Elements

UW-Madison researchers have developed a new power generation structure based on the quantum mechanics of nanostructures. A coupled pair of nanopillars serves as the rectifier in a rectenna for power generation. The rectified electromagnetic signal is used to transfer electrons, which leads to the buildup of voltage. Embedding these nanoscale rectifiers in broadband antennas creates rectennas with the ability to scavenge energy from the radio frequency to optical frequency range. Rectennas with nanoscale power generation devices have the potential to be used as a universal power source.
