Large displacement vertical translational actuator based on piezoelectric thin films.
A novel vertical translational microactuator based on thin-film piezoelectric actuation is presented, using a set of four compound bend-up/bend-down unimorphs to produce translational motion of a moving platform or stage. The actuation material is a chemical-solution deposited lead-zirconate-titanate (PZT) thin film. Prototype designs have shown as much as 120 μm of static displacement, with 80...
متن کاملFault Tolerant Control of a Teleoperated Piezoelectric Microgripper
This paper presents a new architecture of control for micro-teleoperation system using a fault tolerant control (FTC) strategy to compensate for the degradation effects of piezoelectric-based microgipping system. The proposed strategy uses passivity approach for the bilateral controller and robust fault tolerant control (FTC) for the two-fingered microgripper system. First, the bilateral contro...
متن کاملTwo Important Issues Relevant to Torsional Response of Asymmetric 8-Story RC BuildingDesigned with Direct Displacement based Design Approach
Direct displacement based design (DDBD) is a conceptual framework that directly design a structure to achieve an expected performance level under specified seismic intensity. In this study, two important issues relevant to torsional response of mass eccentric 8-story RC building designed with DDBD approach are investigated. These issues are including the effects of unbalanced mass distribution ...
متن کاملFlexible building blocks method for the optimal design of compliant mechanisms using piezoelectric material
This paper presents a new method to optimally design active compliant mechanisms. It is partly based on a flexible building blocks method called FlexIn, which had been developed at the French Atomic Energy Commission (CEA). This method uses an evolutionary algorithm approach to optimize a truss-like structure, made of an assembly of passive and active piezoelectric building blocks from two spec...
متن کاملPiezoelectric Microgripper Equipped with a Smart CMOS Camera
This paper deals with the design of a micro-eyein-hand architecture. It consists of a smart camera embedded on a gripper. The camera is a high speed (10 000 fps) CMOS sensor of 64 × 64 pixels. Each pixel measures 35 μm × 35 μm and includes a photodiode, an amplifier, two storage capacitors, and an analog arithmetic unit. The gripper consists of a 4 dof (degrees-of-freedom) (y+, y-, z+, z-) micr...
