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.
由四個外電極和一個固體或象限內電極組成的徑向極化壓電材料組成的薄圓筒。
當電壓施加到外部電極之一時，致動器壁膨脹，導致管尖垂直收縮并產生較大的橫向偏轉。圓周電極可用于垂直或徑向拉伸和收縮
