Stacked piezo ceramics are also named PZT stacks, are kind of piezo components which are composed ceramic thin pieces with many ceramic layers and internal electrodes. By comparison with london crystals with single-layer, they possess various features including small scale, low voltage, high power, low heating consumption, large deformation and force, and very high displacement resolution, which is able to realize Nano-level control accuracy. It has good piezoelectric property, and the mechanical property is pretty great too, can work in condition of high temperature and voltage. All these features make piezo stacked actuators have wide application market and development prospect in electronic manufacturing industries.
