    • The piezo-electric sensor senses three dimensionally the rotary angle with repect to a 1st axis and a 2nd axis while getting strong to noises except the rotary angle. The sensor comprises: a drive piezo-electric element(11), attached to a bottom of a metallic cube(14), vibrating in the Z direction by an external AC signal; two pairs of rectagular shear type piezo-electric elements(2,12,3,13), attached to four surfaces protruded from a cross shaped support(16) installed on the top of the metallic cube(14), having the same polling direction(X direction, Y direction).
    • 压电传感器三维地感应旋转角度,相对于第一轴和第二轴,除了旋转角度之外,还会感到强烈的噪音。 传感器包括:驱动压电元件(11),其附接到金属立方体(14)的底部,通过外部AC信号沿Z方向振动; 两对直角剪切型压电元件(2,12,3,13),其附接到从安装在金属立方体(14)的顶部上的十字形支撑件(16)突出的四个表面,具有相同的轮询方向 (X方向,Y方向)。
