  • Liang GuoEmail author


Our brain, as an unparallel information processing center, remains one of the largest mysteries of our era. To explore and interface it, implantable electrodes have been designed with a variety of materials and fabrication technologies. These intracortical electrodes have achieved great successes in an ever-expanding research area for more than 70 years and are still under intense developments with the continuously evolving technologies and concepts. This chapter reviews the classic intracortical electrodes, including microwire and micromachined electrodes, with a focus on their designs, fabrications, applications, and challenges.
