Microelectrode Array

Abstract

Microelectrode arrays (MEAs) have been applied as chronical interface with the neural system and play important roles in neural prosthesis for various diseases, including sensory and motion injuries such as blind, deaf, and paralyzed, and also mental diseases like depression, Parkinson’s disease, and epilepsy. Thanks the inherent merits of microfabrication, MEAs show the advantages of low cost, mass production, high density, flexibility (optional), small footprint, integratability with ICs (integrated circuits), etc. In this chapter, we discuss about the general requirements and consideration of materials, design, and fabrication of MEAs in details. Then the various devices and their applications in the central nervous system and the peripheral nervous system are overviewed, respectively.
