DSM, piezo actuators

Piezoactuators are special, ultra-precise short-stroke linear actuators. They convert an electric voltage into a small, precisely controlled linear movement with a high developing force.
The principle of operation of piezoactuators is based on the inverse piezoelectric effect - the mechanical deformation of a crystal when an electric field is applied to it.

FPA: Flextensional Piezo Actuators are efficient amplified piezo actuators with travel from 50 to 2000 microns.

LPA and LFPA: Lever-Amplified Piezo Actuators are simple kinematic lever piezo actuators with travel up to 10,000 microns and many custom variations.

PSA: High-Frequency Piezo Actuators are a kinematic variation that brings higher frequency capabilities to actuated travel ranges up to 1500 microns.

NA: Non-Amplified Piezo Actuators are relatively high stiffness piezo actuators with travel up to 80 microns standard or 300 microns in custom configurations.
