[A review about the research progress of the acoustical-electrical transducer for totally implantable cochlear implant].

ABSTRACT

Cochlear implantation has become a crucial approach for the treatment for patients with severe and profound sensorineural hearing loss. However, some patients would be embarrassed by the exterior components, which limited the patient's social activities. The idea of totally implantable cochlear implant (TICI) was put forward to alleviate these inconveniences. The implantable acoustical-electrical transducer would be a breakthrough in the study of TICI. In this paper, a summary of all kinds of designs ideas was made.
