Osram’s infrared LEDs enable face recognition in smartwatches
Various methods of biometric identification provide the user with security and form a reliable “lock” against unwanted access. For manufacturers of mobile devices, the size of the individual components plays a central role in the design of their products.
The particularly compact dimensions of the specially developed Oslon P1616 package (1.6 mm x 1.6 mm x 0.85 mm) make the SFH 4170S and SFH 4180S the smallest Osram components for biometric applications. Compared to similar products today, the two IREDs require about 50% less space.
Despite the small dimensions, the IREDs uphold an outstanding power of 1150 mW at 1 A and radiation intensity of 280 mW/sr. These characteristics are particularly important for 2D face recognition. This identification method focuses on two-dimensional features of the user’s face.
“Biometric identification will become an increasingly important part of our lives in the future,” said Arne Fleißner, product manager at Osram Opto Semiconductors. “With our two new IREDs, we are making space-saving integration into our customers’ end devices much easier and are thus also helping to protect users’ sensitive data.”
