Flextension

The dominant concept in high strain actuators is the flextension mechanism.

When the cover plate height decreases, the motion of cover plate is from rotation-dominated to flextension-dominated.

. Using homogeneous flextension piezoceramic plates with uneven thickness polarization, as well as monolithic plates with internal electrodes, llows to increase their dynamic strength.

Hinge-lever and flextension-type displacement amplification mechanisms are adopted for the multilayer actuators.
