Microfabrication And Characterisation Of Microelectrode Arrays For In Vivo Nerve Signal Recording

Abstract

The present work was performed in the framework of the ESPRIT-project "INTER" aimed at the development of an "intelligent" artificial interface between the living nerve system and electronic devices. The design, the fabrication, and the characterisation of regeneration-type microelectrode arrays for in vivo recording of nerve signals is described here. The impedance of the microelectrodes could be decreased by electrochemical platinisation. An equivalent circuit is proposed to describe the response behaviour of these electrodes after different preparation steps.
