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 ...

Scientists create UV-enabled flexible wearable technology

To enable the development of wearable devices that possess advanced ultraviolet (UV) detection functions, scientists from NTU Singapore have created a new type of light sensor that is both flexible and highly sensitive.While ...
