Computer Simulation of Volume Conduction Based Data Communication Channel for Neuroprosthetic Devices

Neuroprosthetic devices often require an information channel to communicate with external computers through biological tissue. Traditionally, this channel is provided either by a bundle of wires penetrating the skin or by a radio-frequency coupler. In a different approach, the ionic fluid within the human body is utilized to establish a data communication channel. We investigate a number of important issues related to the antenna of this channel, including the surface shape, curvature, and orientation. The finite element method is utilized to optimally select system parameters according to the dimensions of the neuroprosthetic device and the site of implantation
