Research boosts efficiency and stability of optical rectennas


January 26, 2018

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.
