抄録

Shape memory unimorph actuators have been trial manufactured using lead zirconate-based antiferroelectric ceramics (Pb0.99Nb0.02[(Zr0.6Sn0.4)1-yTiy]0.98O3). In a unimorph structure a slightly higher Ti concentration y(0.0630) is required than that (0.0625) in a simple disk, in order to stabilize the field-induced ferroelectric state; this is probably due to the compressive stress generated in the unimorph configuration. Dynamic response has also been investigated in the shape memory unimorph. Only a short period electric field pulse (<5ms) can drive the unimorph; this gives much advantage in controlling than in the conventional piezoelectric actuators.
