Micro Electrode Arrays (MEAs) have become a technical standard tool to record nerve signals from neural tissue and to stimulate the tissue.

Whereas MEA technology had begun with passive devices - i.e. with chips hav-ing no active electronic devices on board - and with such devices still having a broad application area today, aiming for far increased spatiotemporal resolution within the last two decades active CMOS-based MEAs have been developed.

In this seminar talk, we will highlight related design philosophies of high-density CMOS MEAs, consider CMOS integration issues with respect to interfacing materials, and discuss circuit design aspects with respect to signal-to-noise issues.
