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(nèi)電極組成的徑向極化壓電材料組成的薄圓筒。
當(dāng)電壓施加到外部電極之一時，致動器壁膨脹，導(dǎo)致管尖垂直收縮并產(chǎn)生較大的橫向偏轉(zhuǎn)。圓周電極可用于垂直或徑向拉伸和收縮
