Review on Embedded Sensors and Actuators for
Gentle Insertion of Cochlear Implants (Review)
L.A. Kahrs, Leibniz Universität Hannover, Hannover, Germany
Cochlear implants are the actual treatment of choice for severe hearing loss and profound deafness. One part ofthe surgical procedure is the insertion of the electrode array into the cochlea; more precise into one of its compartments:the scala tympani. The sheath of the electrodes is made from silicone rubber, has a diameter of approx. one millimeter and an inserted length of approx. 25 mm. Insertion of this array is done by pushing gently until roughly one or one and a half turn (360°-540°) of the cochlea is reached. To monitor the insertion procedure and to avoid potential failures during this process (e.g. buckling, tip fold over, rupture of the basilar membrane) research is undertaken. This contribution gives an overview of actual developments towards embedded sensors and actuators into the electrode array.
