摘要：

A middle ear implant (MEI) system that use the differential electromagnetic transducer (DET) was implemented using micro electro mechanical system (MEMS) technology. The DET is designed to have good vibration efficiency and structure that isn't interfered by external environmental magnetic field. In order to preserve the uniform vibration performance, the MEMS technology was introduced to manufacturing the elastic membrane using polyimide that is tenderer than silicon. Using the finite element method (FEM), vibration characteristics are simulated and designed that the resonance frequency of the membrane is closed to that of human ear. The results of vibration experiments showed distinguished performance of the DET. We implemented the MEI system using a DET and implanted it to a dog. Which showed the MEI system had excellent performance and work in a living body.
