Study boosts effectiveness and security of optical rectennas


The investigate team that announced the 1st optical rectenna in 2015 is now reporting a two-fold efficiency advancement in the devices — and a change to air-secure diode elements. The enhancements could permit the rectennas — which convert electromagnetic fields at optical frequencies immediately to electrical current — to work very low-power units this sort of as temperature sensors.
