WN01 series piezoelectric fiber stretcher is a piezoelectric motion mechanism specially designed for fiber stretching application. Its principle is to cause the hinge structure to expand outward through the actuation of three piezoelectric ceramics stacked at 120 degrees, so that the outer diameter expands, thus stretching the optical fiber wound in the outer diameter groove.
