A novel piezoelectric actuator using a two-stage flexure hinge structure is proposed in this paper. which is used in a compact and high-precision electromechanical field. The two-stage flexure hinge structure is used to provide horizontal thrust and vertical clamping force to the driving feet. which solves the problems of unstable clamping force and insufficient load capacity in tradi... https://www.jmannino.com/save-now-3D-Key-Ring-Rainbow-Lorikeet-Pete-Cromer-Wilmot-Harvey-super-grab/
