Preloaded piezo actuator is a device which uses piezo effect to generate displacement. It is composed of piezo ceramic material, metal electrode and packaging material. Piezo ceramic materials will deform under the action of electric field, resulting in displacement. Metal electrodes are used to apply electric fields to control the deformation of piezo ceramics. The packaging material is used to protect piezo ceramics and metal electrodes, while also improving the mechanical strength and protective performance of the device. The preloaded piezo actuator has the advantages of fast response speed, high precision, low power consumption and long life, and is widely used in precision instruments, automatic control, medical equipment, aerospace and other fields. CoreMorrow has hundreds of preloaded piezo actuators that use the inverse piezo effect for micro and nano motion control, and their outer diameter sizes range from 9mm to 45mm, and their blocking force can also be up to 50kN or more. These piezo actuators are available in threaded, flat or ball connections. A preloaded piezo actuator introduced in this paper is different from conventional piezo actuators, it has no mechanical interface, and very small dimension, we name it VS6. The outside diameter of VS6 is only 6mm, the height can be freely selected from 10 to 40mm, its output can be up to more than 200N, and the stroke is optional from 0.8 to 50μm.
VS6 small piezo actuators have many advantages, such as:·Fast response: Piezo actuators have very fast respond and can complete motion in microseconds, making them suitable for applications requiring high-speed response.·High precision: The motion accuracy of piezo actuators is very high, up to sub-micron level, suitable for applications requiring high precision control.·High reliability: Piezo actuators have no mechanical contact, so they have high reliability and longevity.·Low power consumption: Piezo actuators have very low power consumption and are suitable for applications that require low power consumption.·Miniaturization: Piezo actuators are very small in size and can achieve high-density integration, suitable for applications requiring miniaturization design.·No electromagnetic interference: Piezo actuators have no electromagnetic interference and are suitable for applications requiring no electromagnetic interference.
Applications
VS6 series small piezo actuator is applied to an electric field to cause a small deformation of the internal piezo ceramic, resulting in mechanical micro-vibration. This micromotion has many applications, such as TDLAS gas detection. The VS6 series small piezo actuators can be used to adjust the length of the optical path in the laser optical path, thus achieving the adjustment of the laser frequency. In TDLAS (Tunable Diode Laser Absorption Spectroscopy) detection, the frequency of the laser needs to be precisely adjusted to the absorption peak of the detected substance to obtain accurate detection results. Therefore, a small piezo actuator can be used to adjust the frequency of the laser to achieve accurate detection of the substance being detected. In addition, small piezo actuators can also be used to adjust the power of the laser to adapt to different detection needs. The VS6 ultra-small preloaded piezo actuators produce motion at the micron level and have a wide range of applications in the micro and nano fields, such as:·Micromechanical systems (MEMS):Preloaded piezo ceramic actuators can be used to manufacture actuators and sensors in micromechanical systems, such as micro-vibrators, micro-pumps, and micro-valves.·Optics:Preloaded piezo ceramic actuators can be used to manufacture optical modulators and optical switches, which can be used in areas such as optical communication, optical storage and optical imaging.·Medical:Preloaded piezo ceramic actuators can be used to make micro-drug delivery systems and micro-surgical instruments, which can be used in areas such as minimally invasive surgery and precision medicine.·Aerospace:Preloaded piezo ceramic actuators can be used to manufacture micro-thrusters and micro-gyroscopes, which can be used in navigation and control systems in the aerospace sector.·Smart materials:Packaged piezo ceramic actuators can be used to create smart materials, such as smart glass and smart coatings, which can automatically adjust their optical, electrical and thermal properties in response to changes in the external environment.For more information about small package piezo actuators, please contact us by calling 0451-86268790, 17051647888 (wechat ID)!
