![]() Piezo tube actuators can generate axial displacement (changes in length) or radial displacement (changes in diameters). The direction of displacement depends on the placement of electrodes and application of voltage. Tube piezo actuators are monolithic cylinders lined with electrodes that are able to generate radial or axial displacement. Contact us!

Piezo Direct offers a variety of custom piezoelectric tubes and pzt ceramic tubes. ![]() The adaptability of PZT ceramic tubes to different operating frequencies and environmental conditions makes them a versatile choice for industries requiring precise and reliable acoustic performance. PZT ceramic tubes find applications in medical imaging, non-destructive testing, and industrial process control, where their ability to generate and receive ultrasonic signals plays a crucial role. Their tubular shape allows for efficient propagation of mechanical waves, enabling precise control over the frequency and intensity of vibrations. This property makes PZT ceramic tubes essential components in various fields such as ultrasonic transducers, sensors, and acoustic devices. These tubes possess the remarkable ability to convert electrical energy into mechanical vibrations and vice versa due to the inherent piezoelectric effect of PZT. PZT ceramic tubes, constructed from Lead Zirconate Titanate material, represent a specialized form of piezoelectric technology with unique applications. Microdosing, nanodosing, and ultrasound equipment.Piezoelectric tubes are suitable in actuator, sensor, transducer, and ultrasonic applications. Piezo tubes are not typically utilized for force generation, but their diversity and reliability in microscopic applications makes piezo tube elements a great source for accuracy and precision. Piezoelectric tubes have quick response times, high acceleration, and high operating frequencies. Piezo ceramic tubes are compatible with vacuum and cryogenic environments. Piezoelectric tubes are extremely versatile, with fast response times, high operating frequencies and acceleration, and the ability to operate in rigid environments. Piezo tubes with a small inner diameter and/or a large length to diameter ratio has to be extruded. Piezoelectric tubes with relatively large inner and outer diameters can be casted and achieve necessary tolerances through machining. In general, there are two different manufacturing processes to make the piezo tubes. Piezo tubes can be configured with vertically segmented, horizontally segmented, or wrap around electrodes, depending on the desired result of the piezoelectric tube. Axial elongation and radial expansions are achievable with piezoelectric tube actuators, sensors, and transducers. One end of the piezoelectric tube is fixed, while the piezo tube body is responsible for deflection. The direction of displacement depends on the placement of electrodes along the piezo tube actuator, in conjunction with the direction of polarization and the application of the voltage. In piezo tube scanners, lateral deflection of the tube tip is also possible by using striped or segmented outer electrodes to generate axial and XY displacement. The piezo tube will contract or expand radially and axially as soon as a voltage is applied. There are three main configurations of piezoelectric tubes with either plain electrodes, split electrodes, or striped electrodes, which all achieve displacement in vertical, radial, and circumferential directions. Most piezoelectric tubes are radially polarized, containing one or several separate electrodes on the internal wall and several separate electrodes lining the external wall, depending on the intended application. Piezoelectric tubes are thin-walled cylinders lined with electrodes that can achieve axial displacement (changes in length) or radial displacement (changes in diameters).
