Development of a Micro-Gripper Using Piezoelectric Bimorphs
Piezoelectric bimorphs have been used as a micro-gripper in many applications, but the system might be complex and the response performance might not have been fully characterized. In this study the dynamic characteristics of bending piezoelectric bimorphs actuators were theoretically and experimentally investigated for micro-gripping applications in terms of deflection along the length, transi...
متن کاملMicro Manipulation by a Compliant Piezoelectric Micro Gripper towards Robotic Micro Assembly
This paper presents a new design of mobile micro manipulation system for robotic micro assembly where a compliant piezoelectric actuator based micro gripper is designed for handling the miniature parts. The compensation of misalignment during robotic peg-in-hole assembly is achieved by this compliant micro gripper because the piezoelectric actuator has capability of producing the displacement i...
متن کاملDevelopment of Micro Aerial Vehicle using Piezoelectric Fiber Composites
Recently, flapping robots are noticed by many researchers, and many challenges are being made toward the realization of flight motions like insects, birds and so on. The purpose of this work is to develop flapping robots using a new type of piezoelectric material, that is, piezoelectric fiber composites. By using the composites, actuating fibers and sensing fibers can be embedded into a wing as...
متن کاملDevelopment of Piezoelectric Micro-energy Harvesting System Using Voltage Doubler
Nowadays renewable micro-energy harvesting system is becoming attractive, because this energy is free which leads to reduce energy cost. Piezoelectric is one of the common energy harvesting systems. Generally, the output of a piezoelectric transducer is a small AC voltage and its power is also small. As a result, the convertion of this low AC voltage into DC voltage by using rectifier diode is ...
متن کاملMeasurement System for the Characterization of Piezoelectric Bimorphs
Hysteresis is a common phenomenon in various non linear systems including piezoceramic materials. Piezoelectric bimorph devices show hysteretic behaviour, when operating as actuators. In this paper an experimental set-up to investigate the hysteretic behaviour of a PZT is described. The strategy adopted uses a resistive readout scheme and a CCD tool for the system calibration. Moreover, softwar...
