Abstract

A study of motor nerve stimulation by flat interface nerve electrodes (FINE) using a new cuff electrode design based on finite element method, genetic algorithm and computational neuroscience method is presented. The purpose of this study is to obtain optimized parameters of electrode model for higher motor nerve stimulation efficiency. In this paper, the application for the focus stimulation on target fascicle is presented

2. A novel approach to compute the impedance matrix of a cochlear implant system incorporating an electrode-tissue interface based on finite element method

Abstract

This paper proposes to use a new and realistic finite element model of a single turn human cochlea and cochlear implant electrode array with electrode-tissue interface to model the electric field imaging technique, which creates an impedance matrix. Due to discrepancy in the Warburg capacitor in the active and nonactive electrode contacts and electric power lost along the cochlea, the diagonal terms of the impedance matrix is larger than the off diagonal terms, which represent the impedance values of the nonactive electrode contacts. The impedance matrix from electric field imaging measurements is compared with the simulation results
