The enormous usefulness of piezo lies in the direct coupling of electrical and mechanical energy in a simple piece of material. A piezoelectric actuator is mounted in a unique lever transmission design of flexure hinges. It was firstly detected thatĬertain materials create voltages when the body is exposed to mechanical stress. Historically, this phenomena is named direct piezoelectric effect. These generators can convert vibrations directly to electrical power. Our bonding and packaging processes greatly improve the reliability and robustness of the piezo ceramics. Ideal devices to design sensors, energy harvester which provide electrical power for Piezoelectric actuators and motors can be used in a wide range of applications, including haptic feedback, pneumatic valves, active controls and many others. And piezo actuation is famous for the highest known resolution of positioning up to the nm-range.Ĭonversely, a piezo stack actuator generates electrical voltages when forces are applied. Range from grams to tons of mechanical cal load. They act mainly like an expanding element generating a compressive force. The piezoelectric actuator is used in diverse industrial, automotive, medical, aviation, aerospace, and consumer electronics applications due to its simple. Each PiezoHapt actuator is comprised of a multilayer piezoelectric element and a vibration plate, and its body is thinner than other existing vibrators such as eccentric motors. From a point of mechanical forces: Piezo actuators are in operation covering a Stack piezo actuators are used as linear electromechanical drivers or motors. TDK’s PiezoHapt actuators are ultrathin vibration units, capable of realizing such needs. From a dynamic point of view: Piezos are used from static positioning to ultrasonics. The piezo effect offers an excellent opportunity to innovate actuators where the performance of electromagnets has already been exhausted. Piezos areĪpplied for many applications. This is named indirect piezoelectric effect. Immediate reaction take place which can provide strong, fast, and precise actuation. Piezo Motors Linear Motor Positioners Manufacturer PI is a manufacturer of piezo motors and linear motor positioners for a range of different applications and industries. Noliac develops and produces high quality piezo actuators with market leading performance, reliability and dimensions. The length of the piezoelectric stack is directly controlled by applying an electrical voltage. ![]() ![]() To put it in a nutshell: The idea of piezo stack actuators is as simple as it is effective: Piezo are made ofĮlectric active material. Piezo actuators are comprised of specially formulated ceramics that exhibit piezoelectric properties similar tonatural quartz.
