Piezoelectric tube scanners are thin cylinders of radially poled piezoelectric material with four external electrodes and a solid or quadrant internal electrode. When a voltage is applied to one of the external electrodes, the actuator wall expands which causes a vertical contraction and a large lateral deflection of the tube tip. A circumferential electrode can be used for vertical or radial extension and contraction.
由四个外电极和一个固体或象限内电极组成的径向极化压电材料组成的薄圆筒。
当电压施加到外部电极之一时，致动器壁膨胀，导致管尖垂直收缩并产生较大的横向偏转。圆周电极可用于垂直或径向拉伸和收缩
