Developing µLED-Based Implantable Optogenetic Stimulators (Z03)

• Subject Area: Biomedical Systems Technology ; Microsystems ; Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 528760423

Here we propose to develop, validate, and apply the next generation of pre-clinical optogenetic stimulators based on efficient thin-film light-emitting diodes (μLEDs) integrated in mechanically flexible substrates. The main application scenarios are slender, linear µLED-arrays used as optical cochlear and cortical implants, an optogenetic laryngeal pacemaker, as well as 2D arrays for in vitro applications. Key technological objectives are a distinct improvement of the µLED light-extraction efficiency and the long-term implant stability.
