Design and optimization of a XY compliant mechanical displacement amplifier

Design and optimization of a XY compliant mechanical displacement amplifier

Piezoelectric actuators are increasingly becoming popular for the use in various industrial, pharmaceutical, and engineering applications. However, their short motion range limits their wide applications. This shortcoming can be overcome by coupling the piezoelectric actuators with a mechanical disp...
