ABSTRACT
During cochlear implant surgery, atraumatic electrode array insertion is considered to be a crucial step. However, during cochlear implantation, the mechanical behavior of an electrode array inside the cochlea is not known. The behavior of an electrode array inside of the cochlea is hardly diagnosed by normal methods. In this study, the mechanical behavior of the cochlear implant (CI) electrode array is studied. A CI electrode array capacitance sensor system is proposed. It is able to automatically determine the array position as a result of the capacitance variations. Instead of applying sensors to the electrode array, capacitance information from the electrodes will be gathered and analyzed. Results reveal that this sensing method is capable of recognizing electrodes' positions when fed into a pre-shaped model.
