![]() The following are the square piezoelectric actuators, please click for details. In terms of shape, piezoelectric actuators can be divided into square piezoelectric actuator and ring piezoelectric actuator. 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. If none of these products match your requirements, click here contact our engineers to custom your multilayer piezo actuators.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. Multilayer piezo actuators are often used as liner electromechanical. In most cases displacement can reach up to 0.15 of the total product length within a millisecond, while exerting a high force. Multilayer Piezo Actuators feature a longitudinal deformation when a voltage is applied. Shape, finish, material, dimensions, and performance levels can all be customized! The maximum height of these devices can be up to 100mm. ![]() We offer a variety of multilayer piezo actuators. Deformation, the maximum displacement can reach 0.15% of the total length of the product, and a huge output is generated at the same time. ![]() The laminated piezoelectric ceramic actuator is made by co-firing up to hundreds of layers of piezoelectric ceramic film and internal electrodes.The unit height is 36mm, and the maximum stack height of the device can reach 100mm when a voltage is applied, the device can generate a length square within milliseconds. Thus, putting many pieces together creates a multiplicative effect on their transformations’ magnitude for the same voltage, amplifying their power. The charge generated is independent of the size of the ceramic a user is working with (this is mathematically modeled by the longitudinal effect). The underlying principle of stack piezo actuators is the intrinsic quality of constancy. This can be accomplished in two ways: either the components are fired separately and connected later via adhesive (discrete stacks the components are normally discs), or they are co-fired and bound by subjecting them to intense heat and pressure, or sintering (monolithic stacks). Multilayer piezo actuators are created by arranging multiple layers of piezoelectric materials on top of each other. In addition, the piezo stack actuator device can give an extremely fast response as well as high acceleration rates. ![]() This makes piezo stack actuators suitable for high precision applications. Piezo actuators utilize this principle to achieve their precise linear movement, high force generation, and high load capabilities. The electrical charge creates a linear movement and force. A piezoelectric element is a polarized ceramic or crystalline material that experiences mechanical deformation when an electrical charge is applied.
