I needed a multichannel line tracker sensor module for an upcoming project. A quick search found several versions of infrared line tracker sensor modules that met or exceeded my demands, but I picked ...

Infrared-to-visible upconversion devices made by integrating an infrared quantum dot photodetector with an organic light-emitting diode potentially offer a route to low-cost, pixel-free infrared ...

The devices, which operate on a heterojunction-gated (HG) structure, demonstrate high responsivity and detectivity while maintaining a simplified fabrication process. This approach avoids the ...

Many robotic applications require a sensor to detect close or very close obstacles. Typically, reflective-type infrared sensors are used for this task. But the circuit in the figure shows an infrared ...

The applications of eye-tracking devices are endless, which is why we always get excited to see new techniques in measuring the absolute position of the human eye. Cornell students [Michael and John] ...

At the heart of this ultra simple smoke alarm is H21A1, which is a photo-interrupter module consists of a gallium-arsenide infrared LED coupled to a silicon phototransistor in a plastic housing. The ...

A recent study published in Advanced Electronic Materials introduces a self-aligned gate architecture for carbon nanotube (CNT)-based phototransistors designed for ...
