![]() ![]() The piezoelectric effect is one of energy transduction. A simple example is a gas lighter used to light your barbeque.įor industrial use and especially in motion control, it is a bit more complicated: Piezoelectricity means electricity as a result of pressure. In this TOP Tech Talk we explain how to use them.ĭriving piezo actuators with linear amplifiers The piezo basics The solution to this problem is the use of power-operational amplifiers. However, the capacitive character, the required high voltages and currents make the control of piezo actuators difficult. Large forces can be produced at precise and small movements. They are available in all kinds of shapes and relatively cheap. Piezo actuators are widely used in today's applications. It is designed for high-resolution static and low-dynamic positioning applications.Driving piezo actuators with linear amplifiers ![]() This flexure actuator provides 1000µm Z-travel. Flextensional Z-Actuator with integrated Double Motion Amplifier.The integrated flexure guide saves the cost for additional guiding systems when integrating these actuators. These flexure-guided piezo actuators integrate a frictionless high-efficiency motion amplifier to combine large positioning ranges up to 1 millimeter with high stiffness and very fast response.
