Multilayer Piezoelectric Actuators

Piezoelectric actuators that exploit the inverse piezoelectric effect to produce a displacement in response to an applied voltage can offer an alternative to familiar electromagnetic devices such as motors and solenoids. They offer advantages such as greater reliability, lower power consumption, smaller size, and increased positional resolution. This session will allow one to better understand these features and benefits. This training will start by covering a quick introduction to piezoelectric principles and basic structure of the actuator. Then, after comparing KEMET piezoelectric actuators with electromagnetic actuators, the focus will be on explaining the difference of technology and structure of KEMET’s actuators against other makers of multilayer piezoelectric actuators. Finally, mapping which series and products are suitable for what kind of applications will further help in selecting the right product. The training will then conclude with some examples of applications, where precision and speed are key.
