The Fraunhofer FEP demonstrates OLED-based thin-film personal sensors

Researchers at the Fraunhofer FEP Institute demonstrated new UV-emitting OLED devices that can be used as low-cost personal diagnostic devices. The German research institute demonstrated two OLED devices, one emitting in the near-UV and another in the green spectral range. Both can be integrated to sensor applications.

The Fraunhofer showed sample sensors that integrate both the OLED deices and photo-detectors with tunable spectral characteristics. The green OLED is a top-emitting OLED that has a thin-film optical filter and thin-film encapsulation - so that a sample substrate can be brought to be very close to the excitation source.
