Short summary
This paper presents the design and testing of a new large-range compliant microgripper. The gripper arms not only provide large gripping range but deliver approximately rectilinear movement as the displacement in nonworking direction is extremely small. The large gripping range is enabled by a dual-stage flexure amplifier to magnify the stroke of piezoelectric actuator. Finite-element analysis simulation study has been conducted. A prototype of the gripper is developed for experimental testing.
