A 3D-printed piezoelectric metamaterial uses topology-driven charge transport to locate underwater sound sources from a single compact transducer, replacing bulky hydrophone arrays. (Nanowerk ...

A nanowire diode with a built-in electron trap senses, denoises, and classifies images without separate processing hardware, mimicking the retina and opening a path to smarter edge computing.

The fluorescence is picked up by the same objective lens and focused onto a detector, such as a photomultiplier tube or photodiode array. Using a 1.0-NA objective lens integrated into an automated ...

The detection of light at the single-photon level is important for tasks ranging from fluorescence imaging to quantum information processing, reports Neil Savage. High-sensitivity detectors that are ...
