ORGANIC LIGHT-EMITTING DIODES

We use organic light-emitting diodes (OLEDs) for new applications in neuroscience. OLEDs can be structured to cell-sized pixels and fabricated on soft, flexible plastic films, which makes them ideal for implants and on-skin wearable light sources. In our lab, we tailor the properties of OLEDs towards specific bio-applications. This particularly means making devices flexible, structuring to very small pixels (10 - 100 µm), increasing light intensity at low voltages, improving OLED speed, adjusting the emission spectrum towards bi-color emission, and shaping emission into forward direction. We have used OLEDs for optogenetics and for functional imaging of neuronal signals.
