ADR supply SWIR technologies (wavelengths range from 1,050-2,500 nm), gradually mature, and prices begin to reach feasible levels. A new applications, based on PPG technology adopt it. With improving algorithm, wearable devices are increasingly likely to feature PPG-based bio-sensing functions, which can measure not only heart rate and blood oxygen levels, but also other variables including body hydration as well as blood glucose, blood lipid, and blood alcohol levels in the future. It also entered the field earphone.

The advantages of SWIR LEDs is that they can detect chemicals and gasses. They can operate during the day as well as at night. The sensors do not require cooling. Furthermore, they can

detect any kind of invisible laser.

ADR supply SWIR LED’s in the range of 1050-1650nm.
