Present work delivers a systematical evaluation of actuation efficiency of a nano-particle electrode conducting polymer actuator fabricated based on Nitrile Butadiene Rubber (NBR). Attempts are made for maximizing mechanical functionality of the nano-particle electrode conducting polymer actuator that can be driven in the air. As the conducting polymer polypyrrole of the actuator is to be fabri...

the natural frequency and pull-in instability of clamped-clamped nano-actuators in the presence of a dielectric layer are analyzed. the influence of the presence of casimir force, electrostatic force, fringing field effect, axial force, stretching effects and the size effect are taken into account. the governing equation of the dynamic response of the actuator is transformed in a non-dimensiona...

Current rapid development in MEMS area has opened up many possibilities in nano-technology such as nano-fabrication. Among them is nanoscale wiring by both AFM (Atomic Force Microscope) tip and laser beam. Being able to make a relatively small deflection, a micro thermal actuator can be used to control the near field optics of the beam minutely and accurately. In this project, we will investiga...

An extremely precise positioning mechanism has been developed for use in space for optical positioning of large mirrors. The design incorporates traditional mechanical components such as gears, bearings and flexures in a unique configuration covered by two patents. This linear actuator is capable of 10 nanometer position resolution over a range of 20 mm and can operate under cryogenic condition...

In this paper, analytical closed-form expressions to accurately estimate the pull-in characteristics of an electrostatically-actuated doubly-clamped nanobeam are derived and examined. In this regard, a coupled electro-mechanical problem for the nano-actuator is first presented assuming a single mode approximation while taking into account all the possible structural, electrical and nanoscale ef...

This paper presents actually work from development of mechatronic handling devices able to accomplish certain microand/or nano operation tasks. Piezo ceramic structures with (3,1)-piezoelectric effect integrated into the mechatronic system will be used an actuation element. The subject of this paper is structures with more than 1 degrees of freedom appropriate for different microand nano-applic...

An endeavor was conducted to explore the design and development of a two-axis linear reluctance actuator for use as a part of a nano-positioner with the application of serving as a small scale kinematic coupling assembly station. This nano-positioner is designed to be able to accurately and repeatable provide precise motion control of small objects with a resolution on the nanometer scale. This...

Omar Farhan Aljanaideh Concordia University, 2013 Smart material actuators are increasingly being explored for various micropositioning applications. Magnetostrictive actuators, in particular, are considered attractive for micro/nano positioning and high speed precision machining due to their high energy density, resolution and force capacity. The magnetostrictive actuators, similar to other sm...
