چکیده انگلیسی
The influence of domain switching on the electric generation properties of lead zirconate tinatate (PZT) ceramic has been investigated after static and cyclic loadings under various conditions. A PZT ceramic of size Ï8.0 mmÃ0.17 mm, consisting of a tetragonal lattice structure, i.e., c/aâ 1.014, was used. Domain switching occurred as a result of the applied stress, where three different switching modes were employed: (I) simple 90° switching; (II) 90° switching with 90° rotation; and (III) 90° switching with 180° rotation. The rates of the switching mode were different: the simple switching mode (Mode I) was 20%; and both complicated switching modes (Mode II and III) were 40%. The extent of 90° domain switching was different depending on the grain and where the direction of the tetragonal structure (c-axis direction) was affected, e.g., the closer the parallel between the c-axis and the stress direction, the stronger the domain switching. The electric generation voltage increased with increasing applied cyclic stress; however, that voltage dropped suddenly as the stress value was close to its elastic limit. This is due to the 90° domain switching. Such domain switching (reduction of the electric voltage) occurred in the early cyclic stage.
