Technical Report: Piezoelectric Stack Actuators 1. Executive Summary piezo stack

Piezoelectric stacks are high-performance electromechanical components designed to deliver precise displacement and high force by layering multiple thin piezoelectric ceramic plates. By connecting these layers mechanically in series and electrically in parallel, a piezo stack amplifies the small displacement of a single layer into a significant mechanical output while maintaining relatively low operating voltages. They are critical in applications requiring sub-nanometer precision, such as optical positioning, and high-force industrial tasks like diesel fuel injection. 2.
