Soft optoelectronics and ion-based circuits for diagnostics and neuromodulation of the auditory pathway

Understanding and modulating neural networks requires high-resolution recording, real-time analysis, and minimally invasive stimulation.These approaches are crucial for treating sensory dysfunctions such as hearing loss and neurological diseases like epilepsy. Current devices lack soft, biocompatible, and intelligent interfaces, limiting progress in responsive neuromodulation therapies. Our goal is to combine ion-gated transistors (IGTs) and organic LEDs (OLEDs) into the first fully implantable electro-optical system. IGTs will enable efficient signal acquisition and local processing, while OLEDs will deliver precise optical stimulation. This system will surpass today’s devices by offering higher signal-to-noise ratios, resolution, and spatial specificity. We will develop novel fabrication routes, tune material properties, and engineer stable, high-performance devices. The outcome will be a new generation of neural interfaces and deeper understanding of auditory neural networks, and the electro-optical stimulation effects upon them.
