R. Colin Johnson @ eetimes.com: PORTLAND, Ore.–Now before you get all excited by the headline, which is not click-bait according to the researchers, a new kind of nanoscale rectenna (half antenna and half rectifier) can convert solar and infrared into electricity, plus be tuned to nearly any other frequency as a detector. The invention was made […]
