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. 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.

A daptations are possibleįor operation in cryogenic temperature, in vacuum, and in exotic environment such as high-g field or vibration.Piezoelectric tubes are thin-walled cylinders lined with electrodes that can achieve axial displacement (changes in length) or radial displacement (changes in diameters). P iezo actuators can be operated in extreme environments.

Encased actuators with pre-stress mechanism are ideal solution for robust system integration. The piezo stacks are cuboid and have two electrical wires to control the element. The stacks have generally a small size when they are compared with other actuator types This method of operation result in significantly larger displacement.īare stacks are perfect for integration into custom mechanism.

The actuators also allow semi-bipolar operation with anĮxtended driver voltage range of up to-30 V to 150 V. These actuators are "low voltage piezo actuators". They consist of stacked piezoelectric plates which are connected electrically parallel. Sizes from 1 x 1 up to 25 x 25 mm 2 are available. P iezo stack actuators are available in a broad range of shapes and
