Abstract
A prestress-adjustable piezoelectric gripping device is provided, in which a prestressing device adjusts a prestressing force applied to a piezoelectric element of a piezoelectric unit on the basis of a feedback signal from a force-sensing unit, so as to adjust the friction between the piezoelectric unit and a gripping unit. By utilizing the deformation of the piezoelectric element to drive the gripping unit many times, the gripping velocity and gripping force of the gripping unit can be controlled, and the prestress-adjustable piezoelectric gripping device of the invention can achieve a long driving displacement while maintaining high precision.
