Abstract

This paper describes the design, microfabrication, characterization and experimental validation of a 6-contact cuff electrode embedded in a parylene-based flexible support. This type of electrode is well suited for both peripheral nerve recording and stimulation and offers improved spatial selectivity as compared to conventional ring electrodes. Both measured and modeled impedance spectra are detailed. An experimental validation is performed on an earthworm with both multi-contact cuff (MCC) electrode recording and ring stimulation electrodes. Single fiber action potentials, elicited by the electrical stimulation, are well discriminated on the 6 contacts. Spontaneous activity is also recorded with burst of spikes.
