Digital Sun Protection with Ultra-small Ambient Light Sensor With UVA Detection
ams OSRAM presents an ambient light sensor with proprietary UV-A light detection. Monitoring vital signs such as pulse or oxygen saturation in the blood via smartphones and smartwatches has been available for several years. The corresponding UV channel of the TSL2585 from ams OSRAM detects the amount of UV-A radiation in natural sunlight. This enables the user to be warned of excessive UV-A radiation. Thanks to its extremely compact dimensions the sensor is ideally suited for space-constrained wearable and other mobile applications.

Ultrathin Quantum Dot LED that Can be Folded Freely as Paper
Quantum dot light-emitting diode (QLED), which employs quantum dots as a light-emitting material, has attracted significant attention as a promising alternative for next-generation display technologies, owing to its outstanding electroluminescence properties. Since it does not require any bulky components such as backlight units, QLED displays can potentially be manufactured into an ultrathin form factor. A joint research team led by KIM Dae-Hyeong (Professor at Seoul National University) and HYEON Taeghwan (Distinguished professor at Seoul National University) from the Center for Nanoparticle Research within the Institute for Basic Science has previously unveiled a prototype QLED back in 2015. The device had a thickness of only 3 micrometers, which is only one-thirtieth of that of human hair. Due to such an extremely reduced thickness, the ultrathin QLED exhibited outstanding mechanical flexibility, which allowed it to be readily applicable in various wearable devices, such as electronic tattoos.
