Moths Inspire Better Smartphone Screens
One of the things that makes your smartphone so smart is that if you pull it out in the sun, it senses that—and dials up the screen brightness to compensate. But it’s not a perfect solution.
“First of all it’s still not bright enough—you have to remember how respectable sunlight is.” Shin-Tson Wu, a physicist at the University of Central Florida. The other problem, he says of the brightened screen, is it kills the battery.
So Wu and colleagues have fabricated a battery-sparing alternative: an antireflective screen coating. Based on the eyes of moths.
“Nature is so rich! We can learn a lot from nature.”
The thing Wu and others have learned about moth eyes, is that they’re bumpy, studded with tiny projections. That uneven surface reduces…
