Piezoceramic tube actuators of the piezo tube series are monolithic actuators, which contract radially and axially as soon as a voltage is applied between the inner and the outer electrode. Piezo tube actuators are often used in scanning probe microscopes to provide dynamic scanning motions in open-loop operation, and as fiber stretchers. Furthermore they are e.g. employed for microdosing tasks in nanoliter pumps or inkjet printers.
Piezo tube actuators are manufactured to the tightest tolerances (0.05 mm). We can provide tubes with diameters as small as 0.8 mm.
