Sensing & Measurement: Wearable technology is booming, powered by photonics

Wearable devices are rapidly advancing in terms of technology, functionality and size, with more real-time applications. The disruption has already begun in health monitoring.
There is also increased interest in using quantum dots in displays. Quantum dots have narrower band widths than organic light-emitting materials and afford thinner encapsulations. In particular, colloidal quantum dot LEDs (QLEDs) have attracted special attention for next-generation displays because of favorable properties such as printability on various substrates, ultra-thin active layers and high luminescence at low operating voltages. The big drawback for use in wearables is that QLEDs are not deformable in multiple directions. Kim's research group, however, has been able to align red-green-blue pixels with high resolutions up to 2,460 pixels per inch in flexible ultra-thin QLED arrays. "These deformable device arrays highlight new possibilities for integrating high-definition full-color displays in wearable electronics," says Kim.
