    摘要: A cochlear stimulation device comprising an electrode array designed to provide enhanced charge injection capacity necessary for neural stimulation. The electrode array comprises electrodes with high surface area or a fractal geometry and correspondingly high electrode capacitance and low electrical impedance. The resultant electrodes have a robust surface and sufficient mechanical strength to withstand physical stress vital for long term stability. The device further comprises wire traces having a multilayer structure which provides a reduced width for the conducting part of the electrode array. The cochlear prosthesis is attached by a grommet to the cochleostomy that is made from a single piece of biocompatible polymer. The device, designed to achieve optimum neural stimulation by appropriate electrode design, is a significant improvement over commercially available hand-built devices.
