Abstract EN
A piezo multilayered stack of height 10 mm is fabricated using 80 μm thick PZT tapes prepared by tape-casting technique.
About 120 layers of thin tapes are dried, screen-printed with Pt-electrode paste, stacked, laminated, and then isopressed to obtain a green multilayered stack.
Cofiring of the stack is carried out at 1250∘C for 1 h with very slow heating rate (15∘ per 1 h).
The sintered stack is poled at 2 kV per mm in hot (120∘C) silicone oil bath for 45 minutes, and free displacement and block force were characterized.
The actuator generates free displacement of 10 μm (0.1% strain) and block force of 1427 N at 175 V.
In a similar way, a ring-shaped multilayered PZT stack was fabricated; the displacement was measured to be 8 μm.
The ring-type actuator is mainly used for fluid flow control in space vehicles.
