Piezoelectric actuators are transducers that convert electrical energy into a mechanical displacement or stress based on a piezoelectric effect, or vice versa. They have been used widely as a high precision positioning mechanism since it can control a small mechanical displacement at high speed, with the advantages of large generated force, stable displacement, and ease of …

A piezoelectric actuator converts an electrical signal into a precisely controlled physical displacement (stroke). If displacement is prevented, a useable force (blocking force) will develop. The precise movement control afforded by piezoelectric actuators is used to finely adjust machining tools, lenses, mirrors, or other equipment. A piezo actuator can be used to control …
