Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

I've completely swapped my home over to LED lights, and for the most part, I love it. The energy savings are real, and I'm a sucker for all the smart color changing tes. But my biggest grievance is ...

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 ...

While fluorophore-biomacromolecule systems are relatively well known, afterglow luminophore-biomacromolecule conjugates/complexes are rarely studied. Here, the authors report the development of a ...

Abstract: The biomimetic CMOS dynamic vision and image sensor described in this paper is based on a QVGA (304×240) array of fully autonomous pixels containing event-based change detection and ...

Abstract: This paper presents a proof-of-concept image sensor with triple functionality: sensing, energy harvesting and image projection. This triple functionality is achieved by employing light ...
