Research boosts efficiency and stability of optical rectennas

Research boosts efficiency and stability of optical rectennas 01/30/2018 02:04 PM EST The research team that announced the first optical rectenna in 2015 is now reporting a two-fold efficiency improvement in the devices -- and a switch to air-stable diode materials. The improvements could allow the rectennas -- which convert electromagnetic fields at optical frequencies directly to electrical current -- to operate low-power devices such as temperature sensors.
