Jaejin Park, Kyubeen Kim, Tae Soo Kim (first author) and Professor Ki Jun Yu (corresponding author), have successfully developed a wireless solar-powered optoelectronic system that enables long-term neuromodulation in freely behaving subjects without the need for external settings, demonstrating its potential for unrestricted neuromodulation applications. The research was published in Science Advances (IF 13.6), an international academic and the top authority in multidisciplinary engineering.
