Acute performance of the thin-film longitudinal intra-fascicular electrode

A thin-film microfabricated multisite Longitudinal Intra-Fascicular Electrode (LIFE) array was realized as a patterned thin film on poly-imide structure. These electrodes were tested in the acute rabbit animal preparation to determine their recording characteristics for comparison to standard metal wire LIFEs and the cuff electrode. It was found that the tfLIFE provided nearly as high signal amplitudes as the metal electrodes, with greater recording selectivity, making them a promising peripheral nerve interface for advanced FNS and neuroprosthetic applications.
