Piezoelectric tubes—also referred to as PZT tubes or piezo tubes—are critical components in a variety of advanced engineering systems. Their cylindrical geometry and electromechanical responsiveness make them ideal for applications such as fluid dispensing, ultrasonic transmission, pressure sensing, scanning probe microscopy, and fiber alignment. At Piezo Direct, we specialize in the precision manufacturing of high-quality piezoelectric tubes tailored to your exact design requirements.
What Are Piezoelectric Tubes?
Piezoelectric tubes are cylindrical actuators or sensors made from piezoelectric ceramics such as lead zirconate titanate (PZT). When voltage is applied across the tube’s electrodes, the ceramic material either expands or contracts depending on the configuration, resulting in radial, axial, or bending displacement. This electromechanical behavior makes piezo tubes well-suited for dynamic applications that require high-frequency actuation, compact form factor, and precise motion or sensing capabilities.
Custom Manufacturing of PZT Tubes
As a specialized piezoelectric manufacturer, Piezo Direct produces both standard and fully customized piezoelectric tubes. We manufacture tubes with single or multiple electrode patterns, longitudinal or radial poling, and a variety of dimensions to meet the specific electrical, mechanical, and thermal performance needs of your system. Each PZT tube is built using carefully controlled raw materials, tape casting or extrusion methods, and sintering processes to ensure uniform density and structural integrity.
We provide full customization for:
- Outer and inner diameters
- Wall thickness and length
- Electrode materials and patterns (e.g., full-coverage, segmented)
- Poling direction (axial or radial)
- Connection options (leads, solder pads, etc.)
- Environmental protection or housing, if required
Applications of Piezo Tubes
Piezoelectric tubes are used across a wide range of industries where precise displacement or sensing is required in a cylindrical format. Common applications include:
- Scanning probe and atomic force microscopy (AFM)
- Fiber optic alignment and positioning systems
- Ultrasonic atomizers and transmitters
- Microfluidic control and medical dispensing systems
- Acoustic emission testing and high-frequency signal generation
- Inertial navigation or rotational sensing systems

Each of these applications benefits from the tube’s symmetry, high bandwidth, and the ability to produce controlled movement in multiple axes depending on electrode configuration.
