It is a kind of laminated piezoelectric microdisplacer structure.Because the layers of piezo expansion sensor
are electrically parallel, superimposed in both displacement and driving force in series, the operating voltage of piezo discs pressure sensor
is proportional to the thickness of the laminated component film, the thinner composition of the film is operating voltage In recent years, with the casting method such as the formation of internal electrodes and printing thick film, the development of advanced technology is monolithic, so that the piezoelectric ceramic micro can change thickness o f the shifter is less than 0.1 mm and the working voltage of piezo ceramic discs vibration sensor
is reduced to less than 200 V, which is beneficial for miniaturization and mass production of the device. The laminated piezoelectric ceramic can be used for precision optical interferometer, deformable mirror, A biological microscope stage, a scanning tunneling microscope thimble device, an impact dot matrix printer head, and a precision position control device. A laminated piezoelectric ceramic micro-displacement device uses a piezoelectric ceramic micro-designed by the inverse piezoelectric effect of a 1Mhz piezo disc
piezoelectric ceramic that displacement device is a set of electronic components and structural components in one solid state device, with fast response, high accuracy, the output torque and power consumption, without the advantages of gear,mechanical transducer piezo disc
has been used in precision machinery, nano-processing, automatic control, robotics and other high-tech fields.For the piezoelectric microdisplacement, the material is fixed, the higher is the operating voltage, the greater is the nonlinearity of the displacement with voltage changes.In order to reduce the work voltage, increase the displacement, the laminated structure can be used for piezo ceramic pzt actuator .it is a laminated piezoelectric microdisplacer structure.As the layers in the electrical parallel in the displacement and driving force in series on both,The composition of the film is proportional to the thickness, the thinner is the composition, the greater is the reduction of the operating voltage; displacement of the piezoelectric micro-displacement increases with the number of layers.In recent years, with the casting method of forming thick film and internal electrode printing, The development of monolithic advanced technology has made the thickness of the laminated piezo ceramic cylinder micro-displacement device less than 0.1 mm and the working voltage dropped below 200 V, which is beneficial to miniaturization and mass production of the devices. micro-displacement device can be used for precision optical interferometer, deformable mirror, biological microscope stage, scanning tunneling microscope thimble device, impact dot matrix printer head, as a precision position control device.
