Abstract:

We report on the deposition of Pb(Zrx,Ti1 - x)O3 (PZT) thin films by chemical solution deposition (CSD) on stainless steel foils. The electrical characterization proves good ferroelectric properties with a remnant polarization of 38  C/cm2. Since PZT is also piezoelectric the 35  m and 50  m thick metal foils are used to make piezoelectric actuated cantilever beams of several millimeter lengths. Actuated with 10-30 V a displacement up to 32  m was measured in quasi-static mode. In resonance mode the displacement increases several times at the same driving voltage.
