Abstract:

This paper introduces the micro electro mechanical systems gyroscope important technology,category,performance comparison and the requirements of the performance parameters in different applications.The latest research results at home and abroad in recent years on the structure of the micro electro mechanical systems gyroscope are summarized.The structure,processing and performance of the micro electro mechanical systems gyroscopes,which are frame type,tuning fork,vibration wheel,vibration ring,rotors suspension,quality block,double vibrating and so on,are analyzed and compared.Emphasis is laid on the micro mechanical gyroscopes' three research difficulties of drift error,precision and packaging technology and the research development trend of high precision,micro machining dimension,structure and circuit optimization,monolithic multi degree of freedom and monolithic integration.

Key words: MEMS;gyroscope;structure characteristic;key technique
