A walking type piezoelectric actuator based on the parasitic motion of obliquely assembled PZT stacks

Smart materials and structures (Print), 2021
In order to decrease the backward motion and improve the motion efficiency, a walking type piezoelectric actuator has been proposed with two ‘legs’ based on the parasitic motion of obliquely assembled PZT stacks. The structure and motion principle of the

Vibration control of cantilever beam using poling tuned piezoelectric actuator

Mechanics based design of structures and machines, 2021
This paper presents active vibration control of smart cantilever beam using poling tuned piezoelectric actuator. The vibrating response of piezo-laminated cantilever beam is modeled using a lumped parameter approach. The fuzzy logic controller is used to

Nonlinear vibration of conical shell with a piezoelectric sensor patch and a piezoelectric actuator patch

Journal of Vibration and Control, 2021
In this study, nonlinear vibration of a conical shell with a piezoelectric sensor patch and a piezoelectric actuator patch is evaluated. The strain displacement relation is considered to be nonlinear and based on that the equations of motion and ...

Piezoelectric Actuators Characterization

2012 International Conference on Industrial Control and Electronics Engineering, 2012
This paper describes a system to drive piezoelectric actuators over more than one decade of voltages and one octave of frequencies, in order to perform high-speed complex impedance characterization at a user chosen voltage excitation level. This characterization provides information about electrical and mechanical characteristics of the device under ...

Piezoelectric microflextensional actuator

SPIE Proceedings, 2004
This paper presents a novel micro flextensional actuator design consisting of bulk PZT bonded to a silicon microbeam. The fabrication process includes boron doping, EDP etching, dicing, and bonding to produce actuators with large displacements (8.7 μm) and gain factors (32) at 100V.

A comparative analysis of electromechanical model of piezoelectric actuator through Caputo–Fabrizio and Atangana–Baleanu fractional derivatives

Mathematical methods in the applied sciences, 2020
The dynamical characteristics of the electrical and mechanical domains are usually detected by means of electromechanical model of piezoelectric actuator; this is because it manages extremely small displacements in the range from 10 pm (1 pm = 10−12 m ...

Cryogenic piezoelectric actuators

SPIE Proceedings, 2009
In this paper, PMN-PT single crystal piezoelectric stack actuators and flextensional actuators were designed, prototyped and characterized for space optics applications. Single crystal stack actuators with footprint of 10 mm x10 mm and the height of 50 mm were assembled using 10 mm x10mm x0.15mm PMN-PT plates.
