This paper reports on the design and analysis of an integrated micromanipulator for both cell gripping and injection operations. The novel device is actuated by three piezoelectric stack actuators, whose outputs are amplified by mechanical amplifiers. It not only provides a sufficient output displacement for gripping and injecting the cell, but also delivers a higher resolution. Analytical static...
This paper reports the design and development processes of a totally decoupled flexure-based XYZ parallel-kinematics micropositioning stage with piezoelectric actuation. The uniqueness of the proposed XYZ stage lies in that it possesses both input and output decoupling properties with integrated displacement amplifiers. The input decoupling is realized by actuation isolation using double compound...
This paper describes the use of implanted microthermal stimulators for locomotion control of ambulatory and airborne insects. In the long term, this research is intended to support micro autonomous vehicles. Experiments were performed using both resistive (nickel), and piezoelectrically driven ultrasonic (PZT-5A) thermal stimulators on green june beetles (GJB) (Cotinis nitida) and Madagascar hissing...
In this study, the performances of the micropump with active type diaphragm actuated by thermoelectric and piezoelectric have been compared. Finite element analysis (FEA) by ANSYS®8.1 had used to simulate and analyze the deflection of the diaphragm. The FEA model actuated by thermoelectric and piezoelectric is validated by the available data. The success of the model in predicting the displacement...
