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.
目前，人工耳蜗植入是重度和极重度感音神经性聋患者重获听力的重要手段。然而人工耳蜗体外机可能存在使用受限和给患者带来心理问题等劣势。据此，国内外专家提出"全植入"的理念，并认为其是一个可预见的发展趋势。可植入式声电换能器是全植入式人工耳蜗研究中亟待突破的核心问题，学者们提出了多种设计思路，本文将各种设计思路整理分析做一综述。.
