Thin-Film Microelectrode Arrays for Biomedical Applications

Part of the Biological and Medical Physics, Biomedical Engineering book series (BIOMEDICAL)


Microfabrication offers many advantages for the batch manufacture of reliable, microscale electrode arrays. Such arrays have been used for highly localized recording and stimulation of neural tissue. This chapter gives a survey of the most commonly used materials and methods in the fabrication of microelectrodes, including planar silicon-based electrodes, three-dimensional silicon-based electrodes, sieve electrodes, and polymer-based structures. Several techniques for electrode modification with nanostructures are described, including carbon nanotube and conductive polymer nanotube coatings. Biocompatibility is described in the context of central nervous system response to chronically implanted devices, which leads to the eventual development of a glial scar.
