Researchers at Columbia University are working on substantially improving the abilities of brain-computer interfaces by creating a high density electrode array that can stimulate and read the brain at high precision. The research is part of DARPA’s Neural Engineering System Design (NESD) project that is working on all the different pieces necessary to build a truly advanced brain-computer systems.
The Columbia team is developing an electrode array with more than one million points that will interact with brain tissue. The construction would be on top of complementary metal-oxide-semiconductor that will be in the form of a slab that can be relatively easily manufactured. To that effect, the Columbia researchers are working with Taiwan Semiconductor Manufacturing Company to prepare the process.
Here’s a quick video from Columbia University about the project:
