Multiple bioengineering challenges exist today in creating practical, chronic, multichannel neural recording systems for research and for human clinical neural interface application. Specifically, persistent wired connections between user and recording system limit the mobility of both. The transfer of high bandwidth signals to external (even distant) electronics normally requires premature data reduction. Percutaneous, and thus suboptimal, connector components are required. Our group is developing approaches to overcome these limitations via entirely implantable, wirelessly powered and communicating, integrated neural recording microsystems.
