Skin Sustain mode: A 4-minute session of red, blue and infrared LEDs to help enhance skin radiance and maintain skin condition, used after an 8-week course of either Skin Brightening or Better Ageing.

Figure 1: The Sun's power spectrum reaching the Earth and its consequences for solar cell design. The benefits of matching a solar cell's response to the Sun's spectrum are widely used in ...

That means there would be major benefits from improving the efficiency of infrared sensors, such as photodiodes. Researchers at Aalto University, Finland, have developed a new type of infrared ...

The developed device works on the colorimetric principle and consists of an optoelectronic circuit comprising an LED-photodiode detection unit, a transimpedance amplifier unit, a microcontroller (MC), ...

However, [lonesoulsurfer] went a different route with this fun DIY build, creating an oscilloscope with a low-resolution LED display ... to investigate actual circuits. It may not be of great ...

Within these devices, red LED can even be combined with other light therapies, such as blue and infrared, to supercharge the results. Alongside in-depth insight into our top pick, the Dr. Dennis Gross ...

The beacon is just a simple ATtiny13 that flashes a message with an invisible IR LED. To receive the messages, [Kurt] made a scavenger decoder shield for an Arduino. The decoder includes a ...
