Optogenetic OLED-on-CMOS stimulators for neurosensory therapies
Summary
Funded by the Fraunhofer-Max-Planck Cooperation Program, the team will present their innovative OLED-on-silicon-based probes for the first time at W3+ 2024, held in Jena on 25th and 26th September 2024, at booth C12. To achieve precise cell stimulation, compact, locally selective light sources are crucial, a challenge the researchers have addressed with their new technology. MPI-NAT and University Medical Center Göttingen (UMG) are collaborating with partners such as Fraunhofer IPMS to develop the required technological solutions. Fraunhofer IPMS has applied its expertise from the microdisplay sector to develop CMOS-integrated light sources with high pixel density and brightness, coupled with low power consumption. This has enabled the creation of pixelated OLED microsensors that can individually control light emissions along the cochlea, corresponding to specific audio frequencies.
