Recently, the first domestically produced fully implantable artificial cochlear prototype, co-developed by the Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine (hereinafter referred to as "Shanghai Ninth Hospital") and Shanghai microport medical instruments (Group) Co., Ltd. (hereinafter referred to as "Shanghai Microport"), made its first public appearance. The project's chief scientist, Professor Wu Hao, introduced that Shanghai Ninth Hospital and Shanghai Microport have spent 5 years overcoming technical challenges, relying on the microport medical-engineering cross-incubation platform, to conquer the sound acquisition technology of highly sensitive subcutaneous acoustic sensors, successfully developing this first fully implantable artificial cochlear prototype in china. The fully implantable artificial cochlear based on highly sensitive subcutaneous acoustic sensors has a wide sound frequency response range, large dynamic range, and high sensitivity. Combined with the independently developed ai algorithm - SmartSonics, it can significantly enhance noise reduction effects and also enhance music perception ability through the neural stimulation encoding strategy - NeuroHarmony, while being compatible with the functionality of 3.0T magnetic resonance (MRI) scanning.
