Researchers at National University of Singapore (NUS) developed highly efficient, large-area and flexible near-infrared LEDs for new wearable device technologies. A research team led by Prof TAN Zhi Kuang from the Department of Chemistry and the Solar Energy Research Institute of Singapore (SERIS), NUS has developed high-efficiency near-infrared LEDs which can cover an area of 900 mm2 using low-cost solution-processing methods. The result was published on Nature Photonics on December 2, 2019. According to the research, the flexible near-infrared ...

Researchers from Holst Centre (set up by TNO and imec), imec and CMST, imec’s associated lab at Ghent University, have demonstrated the world’s first stretchable and conformable thin-film transistor (TFT) driven LED display laminated into textiles. This paves the way to wearable displays in clothing providing users with feedback.

The new SFH 7060 sensor from Osram Opto Semiconductors is designed to measure pulse rates and the oxygen saturation level of blood. It offers excellent signal quality and low energy consumption. The main applications for this component include mobile devices such as smartwatches and fitness armbands – also known as wearables – for continuously monitoring fitness levels. The integrated optical sensor contains five light emitting diodes with three different wavelengths and one high-sensitivity photodiode.
