压电振动陀螺是一种角速率传感器 ,主要用于一体化摄录机的防手振 ,汽车导航的 GPS信号补偿和汽车底盘的控制系统。随着需求的增加和数字化的发展 ,正向低价格 ,高精度 ,耐环境、低耗电和小型轻量化发展。近年来日本又推出两种新型结构的小型压电振动陀螺 :一种采用双晶片式结 Piezoelectric vibrating gyroscope is a kind of angular velocity sensor, mainly used in anti-vibration of integrated camcorder, GPS signal compensation of car navigation system and control system of automobile chassis. With the increase of demand and the development of digitization, it is developing toward low price, high precision, environment resistance, low power consumption and small and light weight. In recent years, Japan has introduced two new types of small piezoelectric vibrating gyroscopes: one uses a bimorph-type junction
