Research Abstract

In order to realize clinical application of Brain-Machine interface, it is necessary to develop a neural probe which is safe and enables long-term stable recording. In this research, we developed a flexible neural probe which is solid for insertion and can become flexible after insertion. And also we did a research about fabrication of micro structure on the surface of electrodes to achieve stable interface between electrode and tissue.
