The composition structure of high-voltage piezoelectric actuator has thicker piezo layer inside than that of low-voltage, so can withstand higher voltages. The driving voltage of low-voltage piezoelectric actuator is generally about 150V, and the driving voltage of high-voltage piezoelectric actuator can generally reach 500V or 1000V High-voltage piezoelectric actuator have a lower electrostatic capacity, and its blocking force is generally much higher than that of low-voltage. Piezoelectric actuator with multilayer stacked structure have small size, extremely high displacement resolution, fast response speed, and low driving voltage, large blocking force and other characteristics.įrom the difference in driving voltage, stacked piezoelectric ceramics can be divided into high-voltage piezoelectric actuator and low-voltage piezoelectric actuator. Piezoelectric actuators as electromechanical transducers can convert electrical signals into mechanical displacements and apply them to adjustment control systems. ![]() Piezoelectric actuator (piezo stack) are also called stacked micro-displacement piezoelectric ceramics or multilayer stacked piezoelectric ceramic micro-motion actuators, which can be used for micro-positioning, valve control, shock absorption and sound wave generation. ![]()
