Piezoelectric Micro Tubes

Miniature piezoelectric tubes are available with inner diameters from 200µm and with segmented electrodes for scanning applications.

PZT micro tubes are available with inner diameters from 200µm and with segmented electrodes for scanning applications.

PI provides a family of miniature and micro piezoelectric components including piezoelectric tubes (PZT tubes) with extremely small dimensions and very tight tolerances, with outer diameters down to 450µm and inner diameters down to 200µm.

Applications of piezoelectric miniature and micro tubes include: Scanning Fiber Endoscopy, Medical Instruments (Minimally invasive), Ink-Jet dispensing, Nanoliter dosing, etc.

In addition to off-the-shelf PZT tubes, PI also provides custom designs for OEM customers. A variety of electrode designs is available including wraparound electrodes, segmented electrodes for multi-axis motion, and laser structuring for custom designs.  Custom frequency tuning is possible by wall thickness modifications.

Piezoceramic Materials

A variety of hard and soft PZT materials is available including PIC151, PIC255, PIC181.
