TBI is associated with pathologies at the molecular, physiological and structural level, which dramatically impact neuronal circuitry, communication and synchronization within neuronal networks. The disabilities that succeed a nerve trauma could be partially abated by neuromodulation and physiotherapy, albeit not in all cases. Whilst electrical stimulation methods have been used in numerous studies on that quest, recent research invests enormous effort to not only create devices with ultrathin electrodes but also ways to have them function wireless. Photocapacitive devices bear excellent features combining truly capacitive stimulation and enormous room for versatile designs to create devices with unique properties, harvesting the advantages of optoelectronic stimulation, and offering wireless control. LOGOS-TBI is a voluminous research project that brings neuroscientists, applied physicists, biophysicists, ultrastructural biologists and health care engineers of four institutions from three countries. Scientists of Medical University of Graz and Graz University of Technology (Austria), Central European Institute of Technology (Czech Republic), University of Zagreb (Croatia) are dedicated to achieve regenerative responses in the nervous tissue through photostimulation using novel semiconductor photocapacitors. The project was launched in May 2019 and funded by Austrian Science Fund (FWF) “Zukunftskollegs” Program and is open for more cooperation.
