These monolithic components contract laterally (radially) and longitudinally when a voltage is applied between their inner and outer electrodes. Multi-electrode tubes are available to provide XYZ motion for use in manipulation and scanning microscopy applications (PI also provides ultra-high linearity closed-loop scanning stages for SPM and nanomanipulation). Precision and Flexibility: PI Ceramic's Strength PT piezo tubes are manufactured to the tightest tolerances. We can provide tubes with diameters as small as 0.8 mm and tolerances as tight as 0.025 mm. All manufacturing processes at PI Ceramic are set-up for maximum flexibility. Should our standard actuators not fit your application, let us provide you with a custom design. Our engineers will work with you to find the optimum solution for your application, at a very attractive price, even for small quantities. Some of our custom capabilities are listed below: Custom Materials Custom Voltage Ranges Custom Geometries Custom Displacement Extra-Tight Tolerances Applied Sensors Special High / Low Temperature Versions Ultra-High Vacuum Versions Short Leadtime for Standard & Custom Designs Because all piezoelectric materials used in PT tube actuators are manufactured at PI Ceramic, leadtimes are short and quality is outstanding. All standard and custom actuators are delivered with performance test sheets. Amplifiers, Drivers & Controllers PI offers a wide range of control electronics for piezo actuators from low power drivers to multi-channel, closed-loop, digital controllers. Design Dimensions: max. L: 50 mm max. OD: 80 mm min. wall thickness: 0.30 mm Electrodes: fired silver-plated inside and outside as standard; thin film electrodes (e.g. copper-nickel or gold) as outer electrodes optional Options: single or double wrapped, circumferential bands axial segmenting (quartered outer electrodes) Polarization: inner electrode, positive potential Useful Equations Axial contraction and radial displacement of piezo tube actuators can be estimated by the following equations: (Equation 1) where: d31 = strain coefficient (displacement normal to polarization direction) [m/V] L = length of the ceramic tube [m] U = operating voltage [V] d = wall thickness [m] (Equation 2) where: Dd = change in wall thickness [m] d33 = strain coefficient (field and displacement in polarization direction) [m/V] U = operating voltage [V] The radial contraction is the superposition of the increase in wall thickness and the tangential contraction; it can be estimated by the following equation: where: r = tube radius d31 = strain coefficient (displacement normal to polarization direction) [m/V] U = operating voltage [V] d = wall thickness [m] The quartered electrodes option makes XY scanning possible - employing the superposition of the axial and radial contraction, similar to bending devices. These scanner tubes, which flex in X and Y, are widely used in scanning-probe microscopes. The scan range of these components is estimated by: (Equation 3) where: Dx = scan range in X and Y (for symmetrical electrodes) [m] d31 = strain coefficient (displacement normal to polarization direction) [m/V] U = symmetric operating voltage [V] L = length [m] ID = inner diameter [m] d = wall thickness [m] Tube actuators are not designed to withstand large forces (see PICA-Thru actuators), but their high resonant frequencies make them especially suitable for dynamic operation. PT Tubes are also used as transducers in ultrasonic and sonar applications.
