Piezo motor is driven by piezo ceramics, using special mechanical structure design to convert the linear micro-displacement produced by the piezo ceramics into macroscopic linear (or angular) motion of the mechanical plane, with stroke of up to tens of millimeters (or 360° ).

Strain sensors are mainly used to measure the deformation of a structure surface, with very high measurement sensitivity, can indirectly measure mN to kN force, and is suitable for force process monitoring, etc.
