Abstract
I will summarize work in my team to develop photonic bioimplants for controlling and monitoring brain activity. These devices make use of our recent development of ultrathin (<20um), flexible and efficient OLEDs with advanced thin film encapsulation which can be stored and operated for several weeks while fully immersed in water. We demonstrate use of our OLEDs for photo-stimulation of neurons through optogenetics in a number of different model systems, and also show the integration of dielectric filters to realize fluorescence imaging of genetically encoded calcium indicators under excitation by our OLEDs.
