Micro-wire based microelectrodes are commonly used in extracellular electrophysiologic recordings. In ear-lier work, we pushed the limits in number of wires up to nine and introduced Niotrode called bundles. In this work, we present improvement steps in fabrication and post-processing by wet mechanical polishing, leading to very homogeneous front end recording sites with an impedance in the 1,5 MΩ range. We demonstrate the feasi-bility to use wire bundles in an array-arrangement and record from them in acute animal recordings.
