Using an optoelectronic transistor as the tetrachromatic sensor, the system can simultaneously process spectral, spatial, and ...

Researchers in Sweden have unveiled a way to create high-performance electronic electrodes using nothing more than visible light and specially designed water-soluble monomers. This gentle, ...

When most people see a leafhopper in their backyard garden, they notice little more than a tiny green or striped insect flicking from leaf to leaf. But these insects are actually master engineers, ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

There are a lot of options for local weather stations; most of them, however, are sensors tied to a base station, often requiring an internet connection to access all features. [Vinnie] over at ...

Nanosensors are chemical or mechanical sensors that can be used to detect the presence of chemical species and nanoparticles, or monitor physical parameters such as temperature, on the nanoscale. They ...
