Abstract

The need to better understand the nervous system drives the technological advancements in the development of neural stimulation and recording interface. In spite of rapid technological evolution, there are still challenges to realize a large-scale, high-density neural interface. In this chapter, we first discuss the design challenges from the system to the components level for a high-density wireless stimulation and recording system. State-of-the-art technologies for the critical functional blocks in the system, including ultrahigh-data-rate wireless link, suppression of the stimulation artifact, focalized stimulation scheme, and high-density electrode array are also reviewed. At the end of this chapter, a large-scale, high-density wireless stimulation and recording system that integrates those critical components are presented.
