Intracochlear electrode. (a) The electroassembly. (b) Detailed view of the inserted part and electrode injection. The conduction part is made of platinum and the backbone is made of liquid polymer crystal covered with silicone elastomer. The five-micro-pin connector was assembled to deliver electrical stimulation. After exposure of the round window (RW, arrowheads) membrane, the stimulus electrode was inserted, and a reference electrode was placed in the skin near the neck for monopolar stimulation.
