A FLEXIBLE, LIGHT-WEIGHT MULTICHANNEL SIEVE ELECTRODE WITH INTEGRATED CABLES FOR INTERFACING REGENERATING PERIPHERAL NERVES

摘要

It has been shown previously that peripheral nerve axons regenerate through microvias in silicon devices, A major challenge in the design of a biocompatible interface is to establish a reliable electrical and mechanical interconnection to signal-processing and transmission electronics which allows simultaneous multichannel recordings or stimulation of nerves, This paper describes the on-going work of developing a new generation of flexible and extremely light-weight electrode arrays with integrated cables. A process technology has been established to fabricate a multilayer device with micromachining methods, which overcomes the 'classical' separation of substrate and insulation layers, The micromachined electrodes exhibit promising mechanical stability and high insulation resistance.
