Neural electrode design is not dead: Opportunities in the future of electrode array design

John Seymour


The future story of minimally invasive implantable neuroelectronics has yet to be written. The application demands advanced manufacturing, miniaturized electronics, and a revolutionary approach to packaging. Yet the most interesting and challenging problem is to define the best electrode and substrate geometry and where to optimally place arrays of electrodes when seeking to span a network. This talk will focus on the process of choosing the electrode/substrate geometry, trajectory, and target. The implications of lead field theory and biophysical models have driven us toward depth arrays in the applications of BCI and seizure localization. Finally, we will share our progress in manufacturing to achieve our goal of large-scale depth arrays.


Dr. Seymour runs the Translational Biomimetic Bioelectronics Lab at UTHealth and Rice University. He was recently awarded the University of Texas STARS award and a $7M translation grant to study the human brain. Prior to joining UTHealth, Dr. Seymour served as research faculty in the Department of Electrical Engineering at the University of Michigan where he developed novel neural interface systems including stretchable bioelectronics and optogenetic mapping tools. His industry experience includes working at NeuroNexus as a Principal Scientist and was part of the leadership team when NeuroNexus was acquired by Greatbatch Medical. He earned his B.S. with Honors in Engineering Physics from the Ohio State University and his M.S. and Ph.D. in Biomedical Engineering from the University of Michigan.
