A laboratory instrument for characterizing multiple microelectrodes.

The task of chronic monitoring and characterizing a large number of microelectrodes can be tedious and error prone, especially if needed to be done in vivo. This paper presents a lab instrument that automates the measurement and data processing, allowing for large numbers of electrodes to be characterized within a short time period. A version 1.0 of the Electrode Analyser System (EAS 1.0) has already been used in various neural engineering laboratories, as well by one electrode array manufacturer. The goal of the current work is to implement the EAS 2.0 system that provides improved performance beyond that of the 1.0 system, as well as reducing size and cost.
