Development of a Low-Cost Electrospinner for Fabrication of Polyacrylonitrile Fibers as a Precursor to Flexible Carbon Neural Electrodes.

Carbon has recently gained attention as a possible alternative to metal-based neural electrodes. In addition to being ideal for neuronal recording, carbon's chemical inertness, electrochemical stability, and ability to coexist with medical imaging techniques without introducing significant imaging artefacts presents opportunities to use carbon-based electrodes for stimulation also. For flexible interconnections, carbon fibers with a glassy carbon crystalline state are of interest.
