Bioinspired protein creates stretchable 2D layered materials

Nature creates layered materials like bone and mother-of-pearl that become less sensitive to defects as they grow. Now researchers have created, using biomimetic proteins patterned on squid ring teeth, composite layered 2D ...

Color-sorting metalenses boost imaging sensitivity

Researchers have shown that newly designed pixel-scale metasurface lenses—flat surfaces that use nanostructures to manipulate light—can be used to make imaging sensors that are roughly three times more sensitive than ...

A new 3D printing frontier: Self-powered wearable devices

When most people think of wearable devices, they think of smart watches, smart glasses, fitness trackers, even smart clothing. These devices, part of a fast-growing market, have two things in common: They all need an external ...
