Peripheral Nerve Interfaces
Abstract The electrode for the neural interface is located where the independent systems of engineering and biology interact electrically for communication. It is a bidirectional channel through which information flows into and out of the nervous system. This chapter is divided into three main sections. The first highlights fundamental neural science principles that guide the design, development, and selection of electrodes for the neural interface. The second section presents the basic design principles to consider in developing a neural interface. The third section presents an overview and discussion of examples of electrode technologies and their demonstrated uses. The design of any interface must consider application-specific idiosyncrasies. Furthermore, the presentation in this chapter focuses on the design of chronically implantable electrodes but does not discuss electrodes used for in vitro studies. The examples in this chapter illustrate the key design principles to be considered when developing an electrode for the neural interface.
