The shape memory effect was observed in the composition of Pb0.99Nb0.02[(Zr0.6 Sn0.4)0.9365Ti0.0635]0.98 O3. This effect was due to the phase transition from an antiferroelectric to a ferroelectric phase. To obtain the original antiferroelectric state, a small reverse bias electric field should be applied to the ceramic. A mechanical clamper was trial fabricated as an application of shape memory ceramics. A multilayer shape memory actuator was fabricated by stacking 20 rectangular plates and installed in a hinge lever magnification mechanism. The magnification was about seven times.
