Step 1

Listen for details

This is Scientific American — 60-Second Science. I'm Christopher Intagliata.


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 (1)____ to compensate(vt.补偿). 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(vt.编造) a battery-sparing(adj.节约的) (2)_____: an antireflective(减反射) screen coating. Based on the eyes of moths(n.飞蛾).

"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 (3)____, studded(v.布满颗粒) with tiny projections. That uneven surface reduces the reflection of light off their eyes—thought to help the bugs (4)____ predators(n.食肉动物), and see better in low light.


So Wu and his team built a similar surface with tiny dimples(n.酒窝), to cut down on glare(n.强光). He says the dimpled coating could boost the readability(n.可读性) of a screen by five to 10 times, compared to a normal smartphone screen. The details are in the journal Optica.


The tech hasn't been commercialized(adj.商业化) yet, and that could take a few years. Which gives researchers time to take advantage of another property of these surfaces: they're flexible. Meaning the possibility of (5)____ or bendable displays. 


Combine that with the bendy batteries we reported on in a recent podcast, and it looks like the smartphones of the future could be set for a real metamorphosis(n.形变).
