Comparison of piezoelectric actuators in strain and force.

What is it about?

This paper presents measurements and analyses of the strain and blocking forces generated by three different piezoelectric actuators (PXE5, PC5H and Pz28) at low electric field in order to design micro-actuators for nanomotion. The degree of non-linearity and the strain activity are assessed by the introduction of a new parameter with an attempt to relate the capabilities of the actuators to their piezoelectric properties. The blocking forces and the strains were calculated using a finite element method and compared to measurements. The PC5H, a soft type, showed the highest strain and blocking force due to its electromechanical properties
